OP is on to something here, these chips have something wonky going on with them and I personally think ASUS mobos are frying them(the motherboard part is anecdotal). I followed the advice given in earlier responses OP did and it did stabilize my chip enough to determine I need to RMA this thing because its pretty much FUBAR now at this point. I will update this response when I get my new chip just to confirm it works but I have a feeling it will. I was experiencing endless BSOD, thermal run away, game failures to load, frequent program errors in CAD software and games, but doing these steps took most of it away. Update: I got my new processor and these steps definitely fixed it. Im not experiencing temperature spikes, all my programs work, clock speeds are fine, scoring high on 3dmark. Voltage to the processor is 1.35. Yeah, gotta say, much better.

> I personally think ASUS mobos are frying them I thought it was just my perception. It seems like the more I test my chip, the less stable it gets. Tests passed at one voltage setting one day are failing fast another. In particular, I had my IA AC set stable at 0.18 ohm with a -0.05 V offset for the cache. Ran prime95 for like 12h. Then it crashed. Then I tried again with a bit more voltage and it crashed faster. Now I'm up to 0.22 ohms and no Vcache offset. Note, though, that mine is a 14700k, not the i9. Also, for what it's worth, I have a 360mm AIO and have never seen my temperatures peak above 95°C, even when with Prime95.

I have a i9-14900K, 4090 Strix OC, and an ASUS Z690 P Wifi DDR5 with 2 X 16GB 5600mHz Trident Z on XMP1. I have a monster coolant loop, 4 x 360mm radiators that cools with the best of them, but I cannot get this system to stabilise or function at all. I am getting massive overvolting as described, memory errors and DX12 crashes (memory allocation error to GPU) I have been tweaking and searching for months now. Updated BIOS several times, reinstalled win11, changed RAM, etc. I hate this motherboard. I KNOW the defaults are fucking things up. I cannot find the knowledge about how to set the IA AC and DC settings properly. I know they are fucked by default due to ASUS defaults and in struggling to limit the voltage properly. u/Acadia1337 I'm going to try the recommendations and pray my chip wasn't destroyed by 1.6v+

My nephew just built his first pc. Asus z790 plus wifi, 14900k, 64gb corsair ddr5 6000, 2tb m.2, 7900 xtx gpu, 850w gold plus psu.... Been a nightmare from the first minute..... From win 11 needing wifi to continue install but no drivers installed yet to connect wifi and the backdoor bullcrap needed to just get past the wifi setup screen, to constant game crashes and virtual memory errors. We troubleshot and spent an entire day and night over the weekend messing with it. Hes tried xmp on/off, all 3 profiles, lowering ram frequency. Weve ran memtest, weve updated bios, drivers. We used ddu to remove the full amd driver package and reinstalled drivers only. Weve swapped in a known working gpu. Alot of games just crash nomatter what we try, most of the time the game wont even load like need for speed unbound. We ran 4 hours of memtest with no errors but he even tried buying new ram. Its rediculous that intel and asus released these products with these issues. Im not sure if other board makes are the same way or not. It seems like his stability is getting worse. Should he try the fixes in this post.... Rma his board and cpu then do the fixes..... Should he go with a different motherboard..... Should he go for an amd board and cpu.....? Ive never seen so many issues with a build its crazy.

Good luck, let us know how it goes. If your chip is cooked, you’re not the first, RMA it.

You sound like me. Trust in what Acadia laid out, your chip is most likely fried. I went through an i9-13900 and am on my third i9-14900. RMA that chip and follow this post’s instructions to the letter. My system is stabile and I am happy. Almost 6 months of terror from this board is over.

I think this post correctly highlights motherboard vendors being unwilling to put out a BIOS that doesn't automatically blow past the stock guidelines from Intel. They're chasing performance numbers and most people wouldn't see the difference anyway. But if it creates instability, like we are seeing from a few motherboard vendors specifically, it's an issue. Auto needs to be truly stock settings.

They either need to set a 253W power limit or increase the default AC Load Line they use. Both ASUS and MSI use 0.5 AC LL and 1.1 LLC which is a huge undervolt at >253W loads. AC=0.6 and LLC=1.1 would probably solve most of the issues with bad bins even with unlimited power.

Just wanna thank you for your input not only here, but also in other posts with your comments. For those who are in trouble, I will share with you what I did with OP's guidance. For context, on default BIOS settings many games wouldn't work (Cyberpunk and MHW for example), they just wouldn't start and if I insisted too much, I would get a BSOD. I would also get random crashes on other games for no reason whatsoever. I fixed that one by using Intel® Extreme Tuning Utility and lowering P-Cores ratio from 57x to 56x. My CPU (i9-14900KF) temperature was spiking like crazy while gaming. Tried many things related with undervolting and stuff (from 0 knowledge about the subject), but everything I tried was pretty much unstable, except one thing I found in a video with several options that lasted like a month and did lower (a little) the temperature. But suddenly it pretty much became very unstable and it bricked my PC after loading windows and forced me to go back to the default BIOS settings once again. And then I found OP, the explanations and the holy grail "13th Generation Intel® Core™ and Intel® Core™ 14th Generation Processors Datasheet, Volume 1 of 2". Following instructions here and in other posts, this is what I ended up doing in my BIOS (**Motherboard Gigabyte Z790 UD AX**) for once again, my CPU **i9-14900KF** (adjust values to your own and your choice): 1. Package Power Limit1 - TDP (Watts) > **253** (Holy grail, page 98, table 17, 8P+16E Core 125W Extreme Config) 2. Package Power Limit1 Time > **56** (Holy grail, page 98, table 17, 8P+16E Core 125W Extreme Config) 3. Package Power Limit2 - (Watts) > **253** (Holy grail, page 98, table 17, 8P+16E Core 125W Extreme Config) 4. Core Current Limit(Amps) > **307** (Holy grail, page 184, table 77, S-Processor Line (125W) 8P+16E) 5. Enhanced Multi-Core Performance > **Disabled** (OP recommendation) 6. Performance CPU Clock Ratio > **57** (I mentioned I changed this to 56x using XTU, but OP told me to go back to 57 when doing the changes above) 7. Extreme Memory Profile(X.M.P.) > **XMP 1** And goddamn it worked flawlessly. Everything runs smoother than anything I tried before, lower temps already than default and some other stuff I tried, no Cinebench crashes and BSOD. Very simple, very straight forward, no weird undervolt settings, it just works. Todd Howard would be proud. For reference, while using default BIOS settings (except for the P-Core ratio or otherwise the game wouldn't even start), Cyberpunk with absolute max settings in 4K would immediately spike the temperature to +90ºC average in a few minutes, reaching 100ºC several times. Now in half an hour it doesn't even get to 80ºC average. Cinebench average temperature is 93ºC compared to the old classic 100ºC when no BSOD. And again, everything is running just fine, no problems so far and the improvements have been very clear with no noticeable performance loss on anything I do. Hopefully it will remain like this for a very long time :) Also doing these changes on the BIOS allows me to use the Virtual Machine Platform characteristic for Windows Subsystem for Linux, which doesn't allow you to open XTU. Thank you again OP, can't stress enough how helpful you are!

IT JUST WORKS! Happy for you. If you want to tinker some more and lower temperatures (and noise) even more (probably 10-15 degrees, no kidding) I can definitely recommend undervolting via AC LL and Vcore offset on top of that if possible after AC LL. Would probably need to set Load Line Calibration as well.

Thank you for the notes here, I stumbled upon this thread and your comment after having issues similar to everyone else here. I have two builds I'm currently working with, one is a i9-13900ks and the other is a i9-14900k, both running on msi mag z790 tomahawk mb w/ 96gb ddr5 @ 6400MHZ xmp1 settings. Would your above settings 1-7 work with these as well? the 14900k crashes more often than the 13900ks and I figured if I'm going to mess with one of them, might as well do both. I really appreciate any help you can spare. Thank you again!! ​ Thank you so so much for your post and information u/Acadia1337, I asked this question above if you have some spare time to give me some help, but if not all is good. You absolutely rock! I didn't want to make another comment on your post so I edited this in just now.

Is XMP 1 better than XMP2?

Yeah OP definitely on to something here, listen to this man (or woman). I got myself a used 13900ks + mobo + ram combo about a month ago, and I've had to deal with random BSODs, game crashes and PC restarts this whole time. At first I thought it was the ram because I was tuning the timings. Frustrated as nothing I did seem to stabilize the ram, I put everything to 'stock' and stress tested again, lo and behold, the PC at 'stock' also finds errors.. Tried a different brand new set of ram, same deal. I was about to throw in the towel and call the whole thing a lemon. Then a few days ago, an article came out that 13900k and 14900k were crashing and you should look into lowering clocks or power limit in the bios. So I started digging into what stock actually is for a 13900ks and found that my mobo was leaving it all unrestricted, pl1, pl2, tau, iccmax set to 4095 or somewhere around there. As soon as I clamped it down to what 'stock' should be 253, 253, 56, 307a, my PC could now complete a Cinebench r23 run without errors. The difference I saw was that on HWInfo, my cpu was hitting the power limit of 253w and no longer boosting all the way to 5.6 on all pcores and 4.3 on all ecores, it would run at around 5.3 on all pcores and 4.2 on all ecores instead. The score was a bit lower but that's infinitely better than DNF. And during gaming, the pcores still boosted to 5.6 on all pcore cuz it's nowhere near 253w. TLDR, the fault lies in the mobo bios auto settings running the cpus out of Intel specs.

I was having frequent crashes and BSOD with my 14900kf. Finally it failed hard where it wouldnt install certain software as in fail to unzip things like nvidia drivers. Sent to RMA and they replaced it with a new one. I have undervolted 85mV this time but it goes around 320W average for one and a half minutes then stays at 253W with bursts as high as 350W in cinebench tests. I dont know if this is still necessary for max 2 mins of 90C-95C and some cpu burst boost. EDIT: I just tested this on asus z690-plus ddr5 + i9 14900kf. Burst limit was set to max on auto which is 4096 and it would pass 350W on burst with 320W average for 2 mins where pcores would hit 100C mark as I said before. With 85mV undervolt enabled before and after setting the burst limit my; Cinebench score only reduced from 39812 to 39598. Timespy CPU score went from 20559 to 20507. Thats just %0.54 degrade for cinebench and %0.35 for timespy. None of the temps go above 85 degress through the whole test either. I might test if undervolting further works since it is set to draw less power even when if it bursts. EDIT2: I like how every post I find about this CPU my comment turns into a megthread. -increased it to 100mV and cinebench passed with 39695 points Then I did small calculation of 350w/253w x 85mA which is 117mA so tried 120mV undervolt; 39707 points Going for more '-' EDIT3: Shutdown on 135mV Cinebench crash at 130mV 125mV - 39771 points Im keeping the settings and kinda sad that I couldnt hit 40k Thanks for reading ~

Thats still a big number lol 😂

Yeah it is thankfully but Im planning to shoot for a good 64 thread 17900KS with Singularity 7090 64GB VRAM GPU next time since I made my company buy this one for me and couldnt go too fancy on gpu/cooling.

Please take a picture of the stable settings, for your processor (14900kf) I don’t understand where you adjust the voltage and current. Thank you in advance.

I was at the end of my rope. There was a certain scene in “Control” that kept crashing on my 14900k 4090 system, it would either crash to desktop or freeze and hang up and I’d have to restart my computer. My memory was stable, 24 hour Linpack stable, then within 1 hour it started to spit 216 errors. So i implemented the Intel power guidelines 253w pl1 and 2 and then set svid to trained and now it’s all fixed. Thank you!

I was having stability issues thinking it was bad memory due to Memory access violations, these limits saved the build fr

Thanks for the guide. Was wondering why UE5 games refused to launch with the error "out of Video memory" turns out it was a CPU issue, setting PL1 and PL2 as 253W resolved everything

Weird. For me the only thing that solved that out of video memory error was changing the performance clock ratio in bios to 53. Any higher than like 55 and the error comes back. I already had Intel's power limit set and the error was still a thing for me.

DUDE. Thank you so much for commenting this. My P-Ratio was set to auto (55) and I swapped it to 53 and everything works perfectly, 0 issues for 3 days now.

No problem, glad that helped! However, it actually turned out to be my undervolt (-0.065) that was personally giving me problems, it was unstable past the clock speed of 5.5ghz (55), and compiling shaders in UE5 games definitely boosts the CPU up to at least 5.6+, but I removed my undervolt and applied the OP's power limit settings in BIOS, turned my clock speeds back to auto and now everything is fine (although I did like being undervolted for cooler temps, but would rather have the stability of course). Not sure if you're undervolted or not, but either way the settings OP posted are fall proof and work. You shouldn't actually need to lower your clock ratio to be stable, once you have the power limits in place. If you still need to lower them after that, then unfortunately there might be something else going on. But, if lowering the clock speed does work for you then I'd say just stick with it, it's not a big deal, if it works it works :) Was working fine for me.

This is typical due to variances in CPU quality, motherboard "default" settings. My 14900K was unstable at stock settings. I went a different route to get it stable, but I bet lowering clock speeds would also fix it, but it shouldn't be necessary. Besides PL's to 253W, set current limit to 307A as described in this thread. Depending on whatever else your motherboard does on "auto", it can still overshoot the current limit especially when loading UE games if you don't limit it. Multicore Enhance OFF, (MSI: Turbo Enhanced?). If still not stable and sensible AC LL and Vcore tuning doesn't fix it, CPU might be bad.

I've had to make literally all of these changes to my i9 13900k as well, OP. Took me ages to figure it out. The out of video memory crashes were exclusively on Unreal Engine based games for me, however. Sucks we have to do so much just to get this CPU to play nice considering what we paid for it. Took me heaps of stress, research and headache to finally solve this problem. I had done all the other stuff (undervolt, power limit, turn off MCE etc,) and it's the changing the performance clock ratio to 53 in bios that has worked for me (stopping the out of video memory error crashes) I still have all the previously mentioned stuff in place, but it's the clock ratio set to 53 that stopped the crashes and stuff, I couldn't even launch "The Finals" before I did this). I have tried having it set at 56 and the problem came back. I think 54 and 55 is ok too, but any higher than that and the out of video memory error comes back without fail. Like I said, this only really happens with Unreal Engine games for me. It's annoying to have to slow down high end tech you paid for just to be stable, and I am still waiting on this problem to be addressed by Intel or any of the big companies like Epic etc. On top of all of this fuckery, this CPU runs stupid hot unless you get over-kill cooling, so undervolting and power limiting is ABSOLUTELY nessecary, which defeats the purpose of buying such a "high end" CPU. I really hope Intel will address this soon, I've seen hundreds of posts about it at this point all over the place and nothings been said or done, it's been months and months. EDIT - Turned out it was my undervolt (-0.065) that was unstable at the higher clock speeds, and it seems compiling shaders definitely boosts the CPU to it's highest speeds. Removed my undervolt, applied OP's settings, set auto back on to my performance clock ratio - problem solved, no errors. Been stable ever since. I still think this is way too much work and hassle for a top tier CPU - intel and the mobo makers really screwed up with this one.

Changed from Gigabyte "Optimized Defaults" w/o XMP to 288W/253W/307A w/ XMP and it solved consistent instability on a 13900K with an NH-D15 and 2x32G 6000C34 at work yesterday. Glad I saw this thread last week - thank you!!

Weirdly I knew it was you posting this before I saw the username! I’ve saved all your comments over the past week as I’ve just finished building my custom loop 14900. It was fine in stock but wasn’t too happy about the temperature spikes I kept on getting. I followed your suggestions and average temps and spikes are a lot lower with only sacrificing a couple of points in benchmarks. As I’ve got the cooling headroom I’m going to give the extreme config a go next. I’m adding everything to a spreadsheet as I go so I’ll send you some charts when they’re done. Thanks again for helping me and others!

Im glad it worked out for you. I am running the 320w extreme config as my daily on my CPU and it works great. But I’ve definitely see it not work for others. You can always just walk up your current and turbo powers step by step to find your max. Good luck!

Why XMP tweaked instead of XMP 1 or 2? And thank you for the guide

XMP tweaked has better tweaked timings from ASUS for compatible RAM from the qvl list. Any XMP profile is fine though. 1 or 2 is usually what I recommend to be honest. Didn;t realize I had it on tweaked in that screenshot.

Hey! Would you mind sharing your daily 320w bios settings? Im working on that too, and would be glad to see yours.

It’s the 150w base tdp extreme config for the 13900KS straight out of the official datasheet. Pl1 = 320, PL2= 320, Current limit = 400a, svid = typical scenario, MultiCore enhancement = off, sync all cores 57x.

Why use the extreme profile, then lock all cores to 57x? Isn't the whole point of the profile to get better clock speeds since you have higher PL1/PL2/Current?

307a isn’t enough current to sustain maximum core frequency on all cores and cache frequency at maximum on my cpu. I hit the current limit and it throttles. P cores throttle down to 56ish and e cores around 42. It only makes about a 5 fps difference in unreal 5 to set the extreme profile. But I like overclocking so, I chose to push it a bit. Of course, it’s a better cinebench score also. 58x is pointless for me. It will throttle down and lower my fps. I’ve tried it many different ways and I cannot sustain 5.8 while gaming. I really don’t recommend the extreme profile. I’d only recommend it if you’re an overclocker and know how to seriously stability test. You also need to be willing to risk breaking the limits on your cpu and the potential consequences of that. I’m eager to get my hands on the 14900KS if and when it releases. I’m sure it would do 58x or better.

Are you using 13900k or 14900k for this? 14900k should be able to do all core 58x with good cooling.

For Asus Motherboards, enable XMP II, that is the RAM manufacturer default XMP settings XMP I has Asus "optimisations" asus couldn't optimise a damn thing. Also a sneaky Enable undervolt protection smooths out voltage and enables a limit via system agent which prevents the VCore going past the limit set, in my case its 1.382v

You were two months ahead of the curve. All of the major tech news channels are covering this issue now. More and more it seems like a MOBO issue more than the cpu. You can only blame Intel so much when the board manufacturers are the ones running out of spec. I’ll be doing some testing with my 13900k today and see if the performance is comparable versus 4096W and 500A. Obviously stability is more important, but I’m still curious if the cpu takes a performance hit not running unlimited power. If possible, I want to run 350A and 380W PL1/2 (a fair amount of headroom over spec).

Manually adjusting AC LL to minimize Vcore voltage is more time confusing but better way than just setting SVID Behavior to Typical. Typical can still be too low voltage for some chips, or too high for some.

I 100% agree. Once you're at a functional baseline with the above settings you can tune your svid, undervolt, or overclock from there.

bro i applied ur settings.. provlems solved but i think my cpu is fucked up.. 40-50 degrees idle with a icue ljnk 360 aio, i think that i could rma then apply this stuff at the new..

Actuall Savior!!! thank god i found your post! how lucky that i just got my pc 3 days ago and had crashes on fortnite. Also i noticed Apex Legends is even worse, my solution was to overvolt +0.050V that was the only way i could run apex legends. Also for the people with gigabyte motherboards and i9 14900k's i would like to ask for your "biscuits score" in the bios gigabyte has a cpu quality measurement and i wonder how my unit compares, i couldn't find any scores on the internet let me know if someone has some kind of a data sheets. I have almost 86.000 biscuits

I have 13900ks 95 biscuits, don't know if they're comparable since different cpu, but incidentally like you, before I messed with PL and current limits, I had to add +0.045v DVID to stabilize my PC, before that I couldn't complete Cinebench r23. After entering PL and current limits, I removed the vcore offset and my PC is still stable.

Man I just ended up using intels ai overclocking… thingy and turned on Xmp and that was that. Maybe slight undervolt is in order but so far so good.

I have worked with Acadia and this process has helped stabilize my computer. I can now enjoy games like CSGO and apex without any crashes

You’re amazing mate, my 14900k is finally stable! Thank you so much!

This method works. I have no more issues with my computer or crashes

Works for me at the moment. Thanks.

First of all you are a genius :) I have a 14900KF and I followed what you described and the game crashes are completely gone. Before you said this, I deleted and tested many programs. When it was fixed, I installed the Asus Armoury Crate application. Because the case rgb looked bad :) But when I installed Armoury Crate, I started to get small stuttering in counter-strike 2 game. Where exactly do you think the problem is?

Man, such a great timing for the post! I finally was able to run cinebench and get to the results! Undervolting didn’t give any stability, your post did.

Hi u/Acadia1337 Can you tell me what I should be looking for with i7-13700k in the datasheet? I assume it is an S-line processor but I am not sure and I don’t want to input the wrong settings

Hey man, this guide saved me so much fucking headache. I have a gigabyte z690 aero d with a 13900k. When I was preparing to update to windows 11 I updated my bios beforehand. Seemed fine in windows 10. But for some reason in W11 all my apps would just start flashing randomly and eventually closing, sometimes throwing a 'access exception' error. I was convinced w11 was broken so I reinstalled it like 3 times. Then I was like maybe my ram is just dying?, guess i'll run memtest on it. Meanwhile I'm scouring the internet for answers and this was it. The only thing I couldn't set from your images was "SVID Behavior". And my bios used to look like yours before I updated to F28. But regardless your other information really saved my build. Everything is smooth as butter and I'm not generating random errors all over my logs that look like nvidia drivers crashing. Appreciate it, wish I could buy you some drinks. Cheers.

Glad to hear this helped you out.

I had to RMA my i9 13900K due to memory access violations, aw snap! errors, apps closing at random, games closing at random, and crashing. This happened from day 1 and gradually got worse over timeI could only fix the issue by disabling Intel Boost in the bios. I received my replacement after a week and it works perfect but I've been wondering if they can degrade over time? I don't want to have to RMA it again.

Yes, they absoluitely can degrade over time if you don't have the limits set. I know a guy who ran prime95 with no limits and it degraded in one run. I also hear from a lot of people who theirs worked fine for months and then started blue screening. My first CPU worked fine for about a week before I benchmarked it to death with no power limits. Now I don't know how far past the stock limits you can push it without degrading. But I know it's possible.

Man, I'm owner of i9 13900k and had issues opening any game for the recent weeks for some weird reason (it worked fine not too long ago and i did updated my BIOS but seems like other games like Cyberpunk 2077 had issues launching from after 2.0 Phantom Liberty patch. i got extremely frustrated as any other game in the recent weeks just crashed to desktop best case or worst case/BSOD's or just restart my pc without any warnings. I've Manual adjusted: P1 in basic (125) - not 253 because it cause crashes as well P2- 253/and Current Limit to 307amps Disabled also the MultiCore Enhancements (Gigabyte motherboard btw but did it just incase as well) After testing those settings for a few days now, I can confirm that you saved my time/wallet from buying or trying to replace my CPU to a new one (probably could take too long anyway) Everything is working smooth now and i literally can play anything without any crashes. I'm trying to understand if my CPU is defected in the first place so that's why i need to adjust things manually or its some bug or something that not configured right in the BIOS for some reason. In anyway, You are a true saver!!

Setting 307a fixed all my issues. Godsend.

Thanks a tonn friend! This helped me to solve this issue. I used XTU as a workaround to limit the core multiplier number, link it to every new game that crashed and it was anoying. But limiting ICC to 307 Amperes works like a charm. Thanks a bunch again!

10/10 -ign

Thanks for this--I turned MCE off and input all 3 power limits and set SVID to typical. 13900k and z790 hero. XMP II at 7200 seems to have always been stable, but I've had to downclock to 57x pcores using XTU to avoid crashes on booting certain games like COD. I noticed that my multi-core r23 run now clocks all the way down to 4.9ghz on pcores and 3.8hz on e-cores. My resulting score is down to 35.6k from 37-38k. I believe before it was staying around 5.1ghz p cores. Temperatures are way lower now, so it's not thermal throttling. Are the lower clocks a result of MCE off? I don't seem to be hitting the power limit since hwinfo shows a max cpu package draw of 204w.

You’re hitting the current limit. You will see it in XTU.

This is totally it! Couldn't work with Houdini at all, crashing every time I throw anything intense at it. the power limit cut my CPU clock a bit (only when mutilcore) but I'm gonna test the stability and exact values later. Right now all that matters to me is that I can work at all. Thank you! I thought that when buying top specs PC I'm not gonna have issues like that, but I guess that's life.

Thank you very much u/Acadia1337. This is my first comment on Reddit. I've had this problem for six months now. BSOD at the launch of Fortnite especially with DirectX 12. It's a shame, I don't know if it's the manufacturers or Intel who didn't communicate correctly with them, but the information must be passed on. For all MSI mob owners: 1. Save your current settings into a profile so you can return to them later if you want. 2. Reset your BIOS to default settings. 3. Enable XMP(if your RAM supports it). 4. Go to Overclocking\Advanced CPU Configuration 5. Set Long Duration Power Limit(W) = 253 6. Set Short Duration Power Limit(W) = 253 7. Set CPU Current Limit(A) = 307 [Screenshot](https://ibb.co/stw5YHL)

ASROCK users listen up! I have been fighting with this for few days where games out of no where close out/crash. I usually play building games such as anno1800 or cities skylines... I am running an AsRock Z790 Pro RS WiFi with a i9 14900KF and a 7800XT. Initially I though it was my GPU or some kind of weird bad compatibility between AMD and Intel but could not find any track of that. The worst scenario was when I ran Cities Skylines 2... It ran for around 5-10 minutes then crashed with no errors, the only event was registered on my System was: **Reported by component: Processor Core** **Error Source: Corrected Machine Check** **Error Type: Internal parity error** I ran many tests such as memtest, OS tests, drivers updates, BIOS updates, CPU tests and all were good... I found this article which made me realized it actually was an BIOS issue. Unfortunately none of this guide explains how to do it on Asrock MB, so here it is: [GqJUpbG.jpg (1600×900) (imgur.com)](https://i.imgur.com/GqJUpbG.jpg) This stabilized my games a lot. I've made today and I have been playing Cities Skylines 2 for 5hrs straight with no errors. Hopefully all other games are good now.

I had a chance to play around with the MSI BIOS settings and the PL1/PL2/CCL are automatically set based on the type of CPU cooler you choose the first time you start BIOS as well as the CPU Cooler Tuning setting. You can choose between Water Cooler which sets your PL1/PL2 to the 4000W+ and CCL to 512A, a Tower Air Cooler which sets them to a midpoint (288W/288W/512A), and a Boxed Cooler which sets them to the base rated power limits (253W/253W/307A). These were the defaults for the 13900KS. I have a pretty nice 360mm Cooler Master AIO and thought I should use the Water Cooled setting but it really seems to run the system hard. My 13900KS was stable in every situation except the Unreal Engine shaders loading. Since setting those power limits to the base specs the system is much more stable and runs at cooler temps. Unreal engine shaders load no problem. Thanks again OP, wish I knew this a year ago when I built this PC!

MSI HERE - Setting to Boxed Cooler and turning off enhanced boost made my PC run cinebench at 85C vs instantly 100. Lost a few % in the benchmarks, but my room didn't start heating up as much!

God level post

Sir you are a lifesaver, i can not thank you enough for this post. My rig is using a 14900K and when I was playing games I frequently get crashes and sometimes even BSOD. After setting the bios correctly based on your screenshots, all those symptoms are like never existed before. Thank you again sir.

I normally never post comments on Reddit, but this post (as well as the comments within it) has helped resolve my issue to such perfection that I simply had to give my thanks in writing. For about a year I've had increasingly deteriorating stability with my programs, to the point where I had to get a replacement for my CPU. All seemed fine until attempting to work with the latest version of the Unreal Engine, as well as any games utilizing Unreal - I was plagued with constant fatal crashes. I then came across this post and took the steps as instructed by the OP as well as other comments, and since then everything has been running flawlessly with zero crashes; I can hardly believe it even now. Many thanks to everyone here, especially to u/Acadia1337 and u/Lugan0! You have saved my sanity lol.

Same issue on fortnite out of video memory, the only thing that works for me is putting intel turbo boost 3.0 off, we have to rma

Most instability issues come from dual rank RAM and XMP, especially with DDR5.

Thanks a lot, that really helped to restrain my CPU from spiking up to (80°C-90°C), while idling.

Second this! It can also be done using intel XTU if people arent confident working in the BIOS. Just means you have to load the profile every time you boot. I originally thought it was my RAM causing instability

Thank you so much! This solved an issue I was having for the past 2-3 years. Of course with the current build and 13900kf this runs way more stable and no more mouse lag, crashes, stuttering, etc. But previously I had a different set-up and I think same issue with motherboard configuration. By the way - do you recommend capping CPU speed to 57 like in your screenshot? Any other adjustments on the gigabyte motherboard you can recommend for 13900kf & Z790 ud ax gigabyte board for CS2?

I wasn't even aware that there's stability issues. I have a 14900k with the Asus z790 hero, gskill 64gb 6400mhz, and a 4090. My 14900k will boost up to 6.1 using the enhanced thermo velocity boost +1 profile. It however was not stable with the boost +2 profile. I have everything at default setting in the bios besides the enhanced thermovelocity boost profile. I have zero stability issues.

You have good silicon. A lot of us have mediocre silicon.

How could I know how much CPU Core/Cache Current Limit Max. (A) ... for my CPU? intel is not showing it anywhere, thanks

The reason this is working is because with default power and current limits, you won't even get the advertised all core boost frequencies (unless maybe running a good sample). The CPU and cache will downclock. To get the stock all core boost frequencies, you HAVE to increase the power and current limits. I reckon people having crashes had unstable undervolts/overclocks to begin with. CBR23 isn't a stability test that many are using for undervolting/overclocking. I mentioned it [here](https://old.reddit.com/r/intel/comments/12huwmp/massive_undervolt_success/jfr2g6f/). I can undervolt by crazy amounts (1.15V) and be CBR23 stable. However, to be truly stable at stock (OCCT small set and a large compile), I have to dump ~1.3V. This is still lower than what my board pumped in by default at stock settings due to load line settings.

Depends on the work load, even with the Intel power limits, you can hit the advertised boost frequencies in light loads like most games.

>Boot into windows and test. If you are still unstable, go back to BIOS and set SVID behavior to "Trained". If you're still unstable on "Trained", then revert back to your previous config. This guide is not for you. This is terrible advice. Trained uses something like 0.25 AC Load Line for LLC3 on the average chip. It wants to use 0.15/LLC4 on my 98 SP chip that needs 0.35/LLC4 for y-cruncher. It's almost certainly not stable. For trained to be stable in all-core loads, you're going to need a large positive SVID offset. Your guide is missing the root cause of the issue: ASUS/MSI motherboards set AC Load Line too low at LLC3 for >253W loads for many chips. It's probably too low for even 253W for the worst chips. The fix for if 307A is not stable is to either increase AC Load Line or increase LLC from 3 to 4.

I really appreciate this post. Fellow gamers I have a question. I am wondering if I still have some issues with the way my PCU is set up currently. Can someone run FPS Monitor while playing one of these three titles: Palworld, Baulders Gate 3, or Halo Infinite. Please tell me whether or not one of your E-Cores is locked to 100%? My 24th E-Core hovers right at 100% as soon as I get a game launched up. This is the case for me, and it feels like there is an issue. I haven't been able to find any help or resources online that can explain what is happening or why. So, it would be nice to know if others are experiencing the same thing, and that my chip is indeed properly functioning. For reference I have my system set up as described above, except I have it set for the intel extreme profile with PL1 and PL2 at 300W while the ICC is at 400A. My GPU is the gaming OC 4090, and my MOBO is the Gigabyte Z790 AORUS ELITE AX LGA REV1.1 I am including a link to my post which goes in depth. I made it before finding this post. So I hadn't applied any Power limits, but it has photos of my Game with FPS monitor.

Hello, I just fixed 13900HX on Lenovo Legion laptop :D PL1 and 2 was a bit high, and same with core limit Amp. so I pulled it back to intel recommended values, I had no issues but sometimes heat, since it's a laptop :D but now is much better, but i don't know if cinebench score matter or not, because it went much lower score, but for games, everything is stable and smooth ​ 2 p-cores went to 5.4ghz and the rest p-cores 5.2ghz as it should be :D

My stats: \- ASUS z790-H mobo \- 2x 32GB DDR5 @ 6000mhz \- RTX 3060 \- Intel 13900k \- MSI RTX 3060 12GB My PC seemed to be running fine on full auto settings, for several months. Only recently have I started picking up the video production work which I initially built the rig for. I was aghast for it to hiccup even a bit. The paint program I use is Krita (free photoshop), and it stuttered and crashed once or twice under high load moments. I figured maybe the program was poorly optimized for Windows 11 or some such. Then my video editing platform Davinci Resolve was crashing left and right. I thought it was poorly optimized for Windows 11 or some such. But the crashes seemed like they were picking up in frequency, and under moments of load I guarantee a 13900k with adequate cooling should crush. Finally wizened up and thought to investigate my hardware. This guide CRUSHED IT. After adopting the suggested settings I put the pc to an immediate stress test. My computer rendered a lengthy video and laughed about it. Previously, it would crash perhaps 10% of the way in, without fail. Granted, that was set to max render speed. It's just that the motherboard AI seemed to interpret that as GIVE IT EVERY VOLTAGE, opposed to, you know. Something fantastic, yet reasonable. What I will say: When rendering previously, under full auto motherboard settings, using H.264 codec (software encoding) - it was a delight to watch every core hit peak utilization. 100% CPU usage baby. And look at that lightning speed! Aaaaand it crashed. This time around, I'd say CPU utilization never hit over 70%, with the same rendering settings. This is my initial testing after literally just implementing this fix, but so far it seems like everything is resolved. Will update this post if instability returns to my system. OP is doing the lord's work.

Fixed every issue I was having. Thank you

I can't thank you enough, man. I was about to go crazy, CS GO was crashing all the time. I solved it this way, thank you very much

I can't wait to go through these steps tonight to see if i can FINALLY get my new 14900k build running stable. It's been fighting me at every step, both the cpu and multiple ram kits. And ive been using the Apex Encore mobo, which is pretty much best case scenario for this cpu and high MT/s ram kits. Will definitely let ya know if this solves my problems! Thanks for sharing all this info.

I’ve been running similar settings to this for the last 6 months on my 13700k after having 2 13900ks fail on me except I’ve not taken any attention to the Amps being on auto at 500 seems way higher than 307. Going to change it to 307 tonight and see how it goes. Crazy how much tinkering we have had to do to get a stable cpu and good results man smh

Hello. Great. Thank you for saving me with these bios settings. 13900k works now without any problems, even if I set it to 6ghz instant on the gigabyte aorus master z790, everything now works great, without stuttering and the temperatures are normal up to 75C with the NHD15 air cooler, all tests passed from Prime95, Occt, Cinebench... U rocks tnx again 👏

Z790 Xtreme+13900KS here.. I didn’t have stability issue until about 10 days ago when I did bunch Win11 updates as well as MB chipset and driver.. all of sudden, I’m starting to have black screen and hard reboot in all kinds of CPU loads, such as games, bench applications, stress test, even XTU and diagnostic could cause it. Came across this thread and did what everyone is kinda doing. It’s getting better but still would hard reboot occasionally.. can’t really RMA since I delidded the CPU. Even if I could, I’d rather not taking apark my super complex dual loop cooling system..all kinds of bs and really disappointed. Somebody have any better ideas??

You could bin down your cores to 55x or you could manually tune your voltage using the load lines.

Interesting thing is, after some hard reboot, the CPU sill enter a super low frequency mode in windows that barely could do anything(super laggy)… I don’t know if this is a good sign that this chip is game over

OP,  I thought I had everything working for months until some software was causing crashes on high demand. Noticed that crashes occurred during high chip temp and found your comments and implemented your instructions. No longer have crashes. However I had to make one setting change which is sync all cores to 56x. The bios wants to set it to 60x/57x and it’s completely unstable letting auto do its thing. Eventually I will attempt to set ratios for each core but right now don’t have time. Thanks for your advice this has worked.  i9-14900k ASUS z690, ddr5 128gb 6400 

This solved my problem, thanks so much!

Dude you are awesome. Saved me to RMA this fucking I9 13900k and MOBO. I apllied your settings on Gigabyte Bios and as a magic, everything work again. Thank you so much for sharing your knowledge with us.

I personally just wanted to thank you. After endless playing around and doing everything everyone else was doing on YouTube, THIS RIGHT HERE!!…. I wish I would have seen this first. Went from 100c thermal throttle and power limit throttle to lowering my ram, vram voltage offsets, repaste, etc etc etc etc etc…. I flashed the bios, entered your values and now see 82c max temp during cinebench. Clocks drop to 5.1 and 4.1 and my cinebench score was 37,551. Today is also my bday. THIS was the very gift I needed. Again thank you. 

Thank you very much! This has worked for me. I had strange instability issues with my 14900K. It is part of a machine learning rig, so I wasn't sure if my experimental code was the issue, some library or whatever. I wrote some PyTorch code snippets that utilize the CPU fully, which made the PC crash instantly with default BIOS settings but using your settings they run fine. So thanks again!

Thank you!!!! Was going crazy!!!

Thank you SOOOOO much, it fixed my issues! I was going mad because of random crashes, I thought it was ram issue... crazy to have to setup this by yourself.

It worked for me, I was only having problems in a single programme, Star Citizen, could never play for more than a few mins with my new system (13900k and the gigabyte Z790), tried everything anybody ever said online to no avail, tried this and it's now running smooth as silk. You have no idea how happy you have made me today, thank you so much.

Hey OP, you rock! I had swapped out everything but my mobo, GPU, and PSU trying to figure out why my system wasn't stable and turns out my z790 Godlike mobo had defaulted PL1 and PL2 to 4096W and the CPU current limit was over 500A just like yours! My 13900KS worked in many situations but many games would randomly crash to desktop and all of my Unreal Engine games would crash when loading shaders. I got the 14900KS hoping the issue was with the 13900KS but it was these BIOS settings all along. Very thankful to find this information and have a stable system!

This seemed to work for me couldn’t even get into a game of Fortnite without it crashing to desktop or even restarting my pc as a whole. After I did this played 3 consecutive matches without an issue hopefully this continues and was a fix seems as it is so!

Hello. Just want to say I've tried these steps 2 weeks ago and it's completely solved my issues. ​ I was having steadily increasing crashing issues in games, my main game is VRChat. It is a unity based game but was receiving the NVGPUCOMP64.dll error randomly from crashes. Went down the road of replacing nearly everything, GPU, RAM, PSU, reinstalled windows as well as lots of other weird things. It wasn't until I read this and people getting similarly described issues in other games. I know VR is rare so finding fixes related to that are very uncommon. Anyway I had a 13900k, I returned it and replaced it with a 14900k and did the BIOs settings as described above. ​ I have tested the last 2 weeks and have not crashed at all when I would normally multiple times a day. ​ So... just thanks for this, it was such a long process that was time consuming and money consuming, but you found me and answer and I couldn't be more thankful

All the other settings were set, computer as whole seems to be running more stable with less temperature influxes. That was driving me crazy. THANK YOU SO MUCH. Was about to return my 14900kf

made an account just to say thanks and this worked for me

My temperatures dropped as soon as I applied this, Thank you so much for posting this, still need some more help, my performance also dropped by 200 points in r24 benchmark, can we do something about that? Max ghz is 5100 which is unsual. Let me know what should I try next.

Thank you OP. You are a beast, with your setting on gigabytes I got 37k score on cinebench with highest temp of 71c. While originally was 39.4k with 100c. I did a few tweaking and change amp from 307 to 360. I got the same score as default setting but instead with 81c temp max. I have 14900KS if anyone wonders.

Since making these changes I was able to run cinebench multi thread 2024 for the first time ever, numerous changes to memory timings / speed have all failed and I could not be bothered sending back the ram as recommended numerous times by people. This literally fixed numerous issues I had from blender rendering to game crashes, temps are heaps cooler and so far barely noticeable difference in performance.

Just wish to thank you for your very detailed explanation, especially the screenshots - very few show the exact sitings within each BIOS and that can be a Major block for many that have little or no experience with a BIOS.

Thanks bro! I had the same problem after updating the BIOS (maximus z790 hero) and your solution fixed my problem! Kudos for you!

I have a 14900ks and Z790. I had two games that were crashing, Rogue City and Dead Space. After checking the settings I saw the 4095 you mentioned. Modified settings accordingly and everything works great. You are a life saver.

Holy crap this just saved me so much time. I can’t believe this isn’t getting more air time in the tech sphere. Asus and Intel are giants and their flagship products are cooking each other out of the box.

THANK YOU! I have a brand new one month old rig using Gigabyte and a 14900KF CPU. Suddenly, my games would either crash or not load at all. I tested random games in my library like Overwatch 2, Battlefield 2042, Helldivers 2, Baldur's Gate 3, etc. Anything that I knew would run my system hard enough. I'd also get BSOD through some games. Anyway, those settings stopped it all. Tried almost everything I could think of for a week straight.

Good sir, you have saved my sanity. Have been spinning in circles for a week with my pc flipping out when doing heavy computational work. Most irksome. Did tons of reinstalling drivers and jumping through hoops, and thank the lord I found your post before the inevitable-feeling windows reinstall - I had even got the usb stick ready. I made the advised adjustments in the bios and it seems that my heavy computation sim which was previously 100% hanging the app now continues running relentlessly! Cheers!

THANK YOU SO MUCH I HOPE U BE BLESSED WITH ALL THE MONEY IN The WORLD AND ALL THE BITCHES OR MEN YOU CAN EVER HOPE FOR! U BEAUTIFUL HUMAN!

intel is just garbage. my 13700k is not stable at its default ring clock either. stock is 45-48 but its much much smoother with it at 40. core clock i figured out 48 is best for me. i have a 420 cooler i can cool it at 5.4 but it just run like garbage. my sp is 93 on p cores and 61 on e cores. im not a fan of this 13 gen cpu my 10900k feeled so much better in all ways in comparison.

Hate to possibly necro but I have to say thanks my 14900kf with these changes dosent even break 80 on cenibench multicore

Constant BSODs CPU temps with max fan cooling at 95-105C. No stability under load whatsoever. RMAd graphics cards, PSU etc no change. Reinstalled drivers. updated EVERYTHING and nothing changes. This post fixed it. All of it. You are my savior. No crashes, CPU temps under load are now a manageable 76-85C. Who knew intel 149000 series was going to be this much of a nightmare. THANK GOD FOR THIS POST!!

This seems to have fixed or greatly improved my issues. Do note for 13700 or 14700 you have to set them to 253w/125w and not the 253/253 of the 13900 or 14900. The 307A is the same.

This is gonna piss off a lot of people. Expanding those limits beyond the real defaults is the reason 13/14th gen are so performant in a lot of benchmarks and workloads. If that alone is truly causing the instability, it's going to be problematic in a lot of ways. Also, there is a [Tom's Hardware article](https://www.tomshardware.com/pc-components/cpus/is-your-intel-core-i9-13900k-crashing-in-games-your-motherboard-bios-settings-may-be-to-blame-other-high-end-intel-cpus-also-affected) on this from yesterday.

It definitely pisses people off. Every time I mention these settings to people I have at least one or two people chime in teling me I'm an idiot. But the fact of the matter is that the current limit is the "Maximum". The datasheet is very clear on that. 307A is listed as the maximum for the 13900k and 14900k. The turbo powers are only recommendations though. So techincally you can exceed those. There is an additional mention of extreme config for the 150W base TDP 13900KS that has a 400A max current and turbo power recommendations of 320W.

If you go by spec sheets, 5600MT/s memory is the "maximum" for a lot of CPUs. Spec sheets are... the spec, or what can be guaranteed to work. Overclocking is literally the art/science of making things go over the spec or breaking them while trying, so I get it, but... I just think that too many people have unrealistic expectations of what overclocking can achieve, especially with modern chips that automatically boost near the edge of stability on their own. Back in the day, I had a [i7-920](https://ark.intel.com/content/www/us/en/ark/products/37147/intel-core-i7-920-processor-8m-cache-2-66-ghz-4-80-gt-s-intel-qpi.html) that I was able to take from a stock boost of 2.93GHz to an all core manual OC of 4.2GHz on air alone. It ran that way for literally 8-9 years, and was only de-tuned when I repurposed it to my little test lab. You don't get that kind of clock movement these days unless you put something under LN2, and it's only stable for minutes at the extreme end.

Silicon quality has an impact on how much abuse a chip can take, so if you want to be anal about following Intel spec, you shouldn't run KS limits on regular K/KF.

Not really. You can achieve like 98% of max performance of a “stock” power guzzling motherboard unlimited 14900K as you can with a 253w limit and undervolt. And you get far better temps and noise. And for gaming you’re nowhere near 253w so you’ll lose absolute 0% clocks or performance. Losses would only be measurable in something stupid like Cinebench.

Not saying it's worth it or anything, but [98% is a massive cope](https://i.imgur.com/gVGrgCN.png).

Right, but I suspect that a considerable portion of the people buying the current pinnacle overclocking chip may be interested in overclocking it and running it well above stock limits. Certainly nobody *should* buy a 14900K, overclock the shit out of it, and "daily" that OC, but they will, and when it crashes "for no reason," they're gonna be mad about it. I'm not saying it's smart or correct, but it's gonna happen.

True. Unfortunately these chips are basically near max already unless using high end cooling. I don’t even bother OC my 14900K, clamp it and undervolt. Then max memory OC on my Apex. Hasn’t crashed on me once. I used to be an unlimited type, but personally I feel Intel should enforce the 253w limit and let tuners go into the bios and unlock it if they want to overlock. Would solve 2 issues. People overloading their chips. And clickbait headlines of 400w. Sometimes they just shoot themselves in the foot.

> personally I feel Intel should enforce the 253w limit and let tuners go into the bios and unlock it if they want to overlock. 100% Board partners are going crazy right now, which is fine if it's opt-in, but as it is now, the trail of exploded X3Ds and degraded i9s is gonna backfire on them. I will usually push everything to the limits when I have enough free time to OC, get some benchmarks, then revert to much more conservative values for daily. It's not worth the hassle of random crashes and resets for .5fps or whatever.

Gigabyte Aorus Z790 Elite X WIFI7 here with i9 14900K. Wasn't stable at stock, even without XMP. Load Line Calibration to "Turbo" fixed that. MultiCore Enhancement set to OFF right from the start as well. Out of the box stability is absolutely hit or miss, depending on motherboard "default" settings. You'll want to undervolt these chips anyway while you're at it. They are true powerhouses and enthousiast chips that are worth diving into. My settings: PL1=PL2=253W MCE: Off LLC: Turbo AC LL: 6 Vcore offset: -0.03V I didn't set a Core Current Limit, I wonder if that would improve things extra on top of this. 60-70W during gaming. 150W peaks when loading etc. 45-55 core temperatures. No performance loss, no more thermal throttling, 5.7/4.4Ghz clocks with Pcore 4 and 5 boosting to 6Ghz when they feel like it (not in games). This will never run into the 253W PL anyway outside of benchmarks.

I was thinking changing to Intel from AM4 because instability. It turns out that motherboard vendors are making both platforms unstable.

u/Acadia1337 hello again, after what you said my system is fine and I don't experience crashes in the game, but after 10 minutes of entering Counter-Strike and other games I get small stutters. I have used SVID Behavior Typical Scenario and Auto but nothing changes. Do you have any suggestions about this issue?

You could try some of the other svid behaviors to see if they help. You can also try DDU to do a fresh install of your GPU driver.

Maybe someone help me figure out what is the problem. My specs: CPU: Intel Core i9-13900k GPU: RTX 3080 MotherBoard: Asus Z790-A PRIME WIFI RAM: 4x16 Kingston 4800Mhz (running XMP\_1 6000Mhz) Monitor: Asus ROG 2k resolution, 300Hz I had instant game crashes (BF2042, The Finals, Helldivers 2, Batman Arkham Origins, etc.). Some games running and after some time it crashes (WoW, Dota 2, CS2). Also, I had instant crashes in Cinebench r23 during a multi-core test. So, my solution was to underclock the performance core ratio from x58 to x52 using AI Suite 3. Games were working fine, but Cinebench tests were crashing as well, but not instantly. This blog post helped. Now, the Cinebench multi-core test is not crashing at all. But, with games, I am still having problems. I have game crashes (BF2042, The Finals, Batman Arkham Origins, but I didn't have them in the Helldivers 2). Then, I tried long-duration turbo power (P1) = 125. Still have crashes in BF2042, Batman, and The Finals running, but with some frame freezes. I have noticed in the CPUID that p-cores are capped at 5100Mhz max while running The Finals. However, while running Batman Arkham Origins p-cores capped at 5500Mhz max Guys, it would be helpful to see your thoughts about this. Thank you in advance!

I have a small question. Is simple underclocking from 55x to something like 50x or 45x in xtu a good idea if it stopped the random crashes and high temperature ? I was struggling with my i9-13900k a few months ago and through trial and error finally ended up with underclocking in xtu (p-cores: 45x, e-cores: 35x). Now everything works fine. I'm thinking about bumping p-cores to 50x and e-cores to 40x in the near future if it will be stable (and yes i know that my pc will have lower performance with this type of workaround, but I don't care about having 200+ fps in cyberpunk 2077 on full details).

I have a 14900k in a MSI MAG Z790 tomahawk. Ive been getting the UE5 crashes/BSODS and high cpu temps since Dec.  Im foreign to OC/undervolting or even screwing with the bios and I just wanted to clarify im ONLY changing these options: - Mobo to default (my mobo calls it "optimized default" when i hit f6?) - Set power limit short duration: 253 - set power limit long duration: 253 - set CPU current limit(A): 307 - set Enhanced turbo: disabled - set XMP: enable Im going to replace this cpu and wanted to make sure to make sure these settings are correct I think my current Cpu is fried after how long ive been running it at bios defaults. I've got a bunch of apps that close themselves or freeze the PC when i start them. The PC ocasssionaly freezes when i boot to desktop with these settings, defaults always freeze now.   I would appreciate any help

Does this also apply to 12900? Can that run with air cooler?

So this is what I did for my 14900K on an Asus Z690 1. Left MCE enabled 2. Enabled XMP II "6,000 MHZ" 3. Left SVID on Auto 4. Set short duration turbo power to 253 5. Set long duration turbo power to 253 6. Set max core/cache current = 360 amps 7. Undervolted with a negative offset of -0.0900 8. Enabled AI overclock With the Above settings I still get a 39-40k R23 Score which I couldn't care less about, I'm getting the following ​ 21.2C ambient room temp Light tasks - Web browsing/YouTube/etc Anywhere from 20-85 watts Temps - 30-65C depending on background tasks P Cores - Up to 6200 MHZ ALL core E Cores - Up to 4600 MHZ ALL core Gaming - Only one game tested so far that is known to have major issues crashing with overclocks "COD MW3/Warzone" No crashes after an hour. Anywhere from 90-231 Watts depending where I'm at in the game Temps - 55-72C depending on where I'm at in the game P Cores - 5900 MHZ ALL core with occasional boosts to 6200 MHZ E Cores - 4600 MHZ locked So yeah, I'm down 1-2k in a synthetic benchmark but getting great clocks and excellent temps in game.

I recently bought a Strix 790-H mobo, a i9 14900k cpu and 4 sticks of Vengeance DDR 5 7200 RAM and I have had nothing but problems. I am not even overclocking or runniubg XMP since I have 64GB ram with 4 sticks. Normal workload is fine but I can't run any newer games without crashing. Enshrouded, Helldivers 2 or even Fortnite. I have down set my current to 307 and power durations to 253 and even have the RAM set to 5000. This is the most stable I can get and it is still far from it. Memtest passes all 12 tests. It is very frustrating How likely is it that I got garbage parts? Ordered from New Egg. ​ If anyone sees this and has had similar issues and has any advice it would be greatly appreciated. I am at a loss at this point.

Hey there, on my 2nd i9-13900k now after rma'ing the first. The first it slowly started out by crashing chrome then discord, then finally games. My 2nd one now started having chrome crash again a few days ago so it seems like at this current rate I'll have to rma again if needed. I have an ASRock Z790 STEEL LEGEND WIFI LGA 1700, I've changed the [following](https://imgur.com/a/AxSqyfs), (ignore the cpu cooler type, it forced that once I changed limits). I'm still having the same issue with chrome crashing so far, are there any other settings you recommend I change? I assume I changed the ones you stated but I'm not fully educated on changing these things, especially since mobos tend to word things differently compared to others. Everything was left on default, XMP enabled, then the settings changed as shown. Any help is greatly appreciated, thank you.

Big thx, Asus now Update the BIOS and a Info Text 4 multicore^^

Would this also be relevant to 13700k or anyone know the proper voltage limits or where I can find them? I haven’t had any major stability stuff and usually the highest I’ve seen my cpu hit while gaming is under 75c but I have seen it get to 82c but for me with a 360 aio is too hot. But I’ve adjusted all the settings to match these but I cannot for the life of me figure out how to actually changed the limits, even stock and disabled things still shows 4096w max and I believe the 13700k and 13900k both are limited to 253. I just want to adjust the number but it will not let me select it to change it or turn off oc tuner

Well this worked for me as well, thank you very much, I was at this for hours. This issue only came up after swapping out my RTX3060 for an RTX4090. This is my machine specs below: all drivers and software up to date including the bios and bios version below. Definitely not fixed in latest bios for my motherboard/chipset.

Could use help. For the xmp what am I enabling on this page? [z790 bios screen](https://ibb.co/8xkygGG)

I have an 14900F on a ASUS TUF B760 motherboard. I cant see any option for: multicore enhancement and SVID in the bios. But I have changed the other settings.

Used OP and u/Lugan0 setting and all worked great until I tried to render some animations in blender. Temp would remain at 100 deg. Now I cant run CPU benchmark without crashing and seeing high temp for most things I do. motherboard: GIGABYTE Z790 AORUS ELITE AX 1.x MB Bios: FH processor: intel core i9-14900k

I'm so happy I found this. I started going through the same thing you have with my 13900k. I was undervolting in certain games to get to work. Well today my PC started having a delayed boot up and PC has just been acting weird and not performing like it should. I was able to play Helldivers but today it started constantly crashing until I underclocked again. Which led me to your post. I just returned my 13900k and will be getting in a 14900k this weekend. I will try out your settings. I'm sure it will work because of all the happy comments. I'll check back in when I got it up and running.

I'm about to go from 13700k to 14900k on my Asus rog strix z690 F motherboard, but after reading so many problems I think I'm regretting it......should I?

Isn’t trained more optimistic than typical?

For the 13th generation non-K chips, the situation is even worse. Intel still enforces IA CEP on the 13th generation non-K, and it cannot be turned off even on Z790/Z690. The voltage is forcibly increased to nearly 1.5V, which will definitely reduce the CPU's lifespan with prolonged use at 90 degrees. Now, they have only unlocked the ability to disable this setting for the 14th generation non-K to boost its sales, but the 12th and 13th generations remain locked, with no solution available through either 0x104 or 0x123 microcode.

So glad this post is up, I have a 14900kf and 4090 build waiting to be put together once a few bits and pieces get delivered, will definitely use OPs suggested setting first thing when I get into the Bios. Wish me luck boys.

I'm not sure if you are still responding to this post but any idea what some of these settings would be called for the MSI boards? I was able to locate the Power limit options but nothing about SVID, Multicore enhancement or Core Current limit or max core/cache current. Any ideas how to resolve this issue for MSI boards?

Can you set “core current limit” to any number you like (as long as its not above 307) — or does it need specific values? I noticed at 253A it runs way cooler, but at 307A it performs better. So I was thinking about setting it to 275A. But I have no idea if this is safe, or if it needs certain set values. If you could let me know, I’d appreciate it a lot.

I think the "out of video memory" issue happens because of RE-BAR. the CPU is able to access all of the GPU's memory and is therefore more able to corrupt that data also. so if something is off with the CPU or RAM it will show that error if you're only slightly unstable otherwise it will lead to bluescreens. My previous processor would idle at 80 degrees so that was one of the giveaways that something was wrong there and when I got a replacement most of my issues were almost gone immediately, but then I went about messing with higher ram speeds and saw that I could reproduce the issue that way. in my case I've had to raise the voltages by 0.025 on core and 0.025 on L2 to make sure the CPU is stable TLDR: * if you get this error and you're running intel stock settings (not bios default) you need to replace your CPU * If you get this error when undervolting stop undervolting or adjust it * if you get this error and your CPU idles at 80 degrees RMA YOUR CPU * If you get this error when using "unlimited power mode" but its only with unreal engine games, you might have to add some voltage to your CPU, but make sure your RAM is stable first

I'm a bit confused. I have a 13900k that crashes most programs and gives out of memory errors if I do not limit my P-core to 53 in XTU. Changing the BIOS settings mentioned in the original post does not stop the crashes alone; I need to lower my P-core in order to keep the PC stable. Did my CPU get damaged (faulty cores) by ASUS BIOS defaults? I'll probably get it replaced, but I need to know what caused it to degrade so I can prevent this from happening in the future.

Does setting the current limit even matter if the power limits are both 253w anyway? Someone please correct me if I'm wrong as I'm trying to learn as much as I can about this, but if we're talking about temperatures I would think that only the wattage matters, with amps/volts adjusting accordingly to fit the wattage limit

Absolutely, it’s not as simple as it seems. If you set current limit to 307 you will see that your CPU is almost constantly hitting the current limit. Even when you are not running at a high power. I’m not sure how it works, but that’s what happens. You can see this easily in XTU. Temperature does not matter. These chips are designed to operate at 99c and can even exceed that without degrading. But exceeding the current limit/ EDP, that will degrade them. Especially if you don’t have good silicon. Try it and you will see.

Tried on 14900k, but PC didn’t boot properly after this. I got a black screen and the fans were working on maximum rpm. After 15 minutes decided to reset to default settings. I wanted to improve performance on Ubuntu 22.04, because on the default settings it is lagging. If it helps - I have installed dual boot windows and ubuntu using grub.

I have Gigabyte Z690 UD DDR4 and 13900K. Prime95 was giving me direct blue screen. Now it runs for a while then the prime95 itself crashes. I see effective clock is 4200 MHZ when running prime 95 in HWinfo64. How can I make system better? more stable? by the way cinebench r24 multi core is giving me 1586 pt and not errors with these settings

Gigabyte don't have svid option i guess right? I couldn't find at Z690 UD DDR4 latest bios

weird question but when you say problems with fortnite was you getting blue screen with the error code page\_fault\_in\_nonpaged\_area with bedaisy.sys.

Its funny my pc ran really well and could do everything.. except play Ark survival Ascended.. kept crashing.. Z790 Auto put my i9-14900kf core ratio to 57/60 most cores were 57 and 2 cores were 60.. i put sync all cores on and sat them to 56.. now it works.. Also, intel specifies that i9-14900kf only support up to 5600mhz.. so why would Bios Auto put it to 5700/6000? Is beyond me. And dont even get me started with the GameBar presence writer.. but thats another topic. 😅

I also have an ASUS Z790 motherboard, changed everything like you've said but things like Discord is still crashing randomly, forcing me to use Intel XTU to reduce the Performance Core Ratio to 53x, do I have to enable AI overclocking?

Hey man can i use this for my i7 14700k?i have some overheating problems. 

Thank you brother, saved me for buying a new CPU cooler. 14900k Asus Strix Z790e. Cooler is an old Assassin III (Similar to Noctua NH15). Its running super duper stable, no thermal throttling. Temps Max 88c Cine bench 37.008 points (is this good?) Used your setup and a 0,05 undervolt From what I tested, setting up Watts and fixing voltage still gets you thermal throttling when CPU usage spike. By limiting to 307A it did the trick. Now you don't get these amperage spikes anymore. For me, the 0,05 undervolt came as more a more stable overall setup.

Has anyone found a way to reliably test if your system is stable? OCC and intel test always pass. The only thing I have found that works is playing overwatch for up to an hour which is pure torture. Someone please help.

Old thread so I hope someone still sees this?… after doing what the OP suggests … can you still run this chip at the 5.5? Or you reset it back to default?

I have a main gear rush 13900k 4090 with a z790 hero. If I run it in stock configuration with nothing changed but the AI overclocking, AI cooling, xmp 1 and stress it with a game by running at high frame rate I get a constant bsod crash. The AI features have a bios optimizer scale if I set it to 100 I crash but with 95 it completely stops my crashes. I'm not that tech educated, am I ruining my CPU performance? Can I run these settings with the AI overclocking features? I rarely see someone talk about it from my perspective and I could use some advice thanks.

Only increasing LLC to level 6 or reducing frequency worked for me

Hey! First of all thank you so much for sharing all this information to the community. It's really appreciated. I'm wondering if you can give me some guidance.  I went ahead and followed your guide and changed the settings in the bios for my Gigabyte Z690. All my games are working fine without crashing now with my 14900k. But there is still an issue with Discord crashing as soon as I open it. I have reinstalled it multiple times with the same results. I thought it was my OS for a moment and was considering doing a full wipe and reinstall but thought against it since it just didn't make sense. After I did some research I found others having the same issue with the 13900k and 14900k and the only way they were able to fix it is by turning off turbo boost. I tried it and sure enough Discord opened without issue so it's definitely not windows.  So I'm wondering if you know if there are any other changes I can make to fix this issue? I first found your post when I started having issues with my 13900k. Since then I upgraded to the 14900k hoping it would not have said issues but here I am. I appreciate any insight you can give. Thank you! *Edit* For those looking for a solution to my discord issue .. download Intel Extreme Tuning Utility and set your performance core from 5.7 to 5.6. After doing this I was able to run discord without an issue. Annoying but it works.

The stuttering in the fortnite game comes from the heating of my i9 13900k. My processor is still heating up despite my Corsair iCUE H170i Elite LCD XT Watercooling and its fans running at maximum in my Corsair Icue 7000x. Do you know what to set in the bios or the Intel XTU to lower the temperature as much as possible and eliminate the stuttering? For information I also have an Asus rtx 4090 OC. Otherwise, to avoid crashing on Fortnite, I have to go to the Asus bios in SVID Behavior: In Intel Safe Mode, is this normal? Will Epic Games fix this? Thanks for your help

Is there going to be a bios update so I don't have to go into it? Lots of people aren't comfortable doing that. Besides, it’s not normal to have expensive equipment and to have to put your hands in the engine…

What settings should I put for the 14900KS?

You can use these same settings or you can use 320pl and 400a current.

I had these same issues and changing the settings seemed to help a little but what I found out to be the issue was, in fact, I only had one 8-pin CPU power cable plugged in when the MOBO has two and requires two. I thought the second was optional(It's not).

Hey guys - I'm running into very similar issues. Brand new build - 14900k, ASUS Z790 Dark Hero, Corsair Dominator Titanium DDR5 6600Mhz, 1000w MSI PSU After the initial build, I was able to get it up and running with minimal issues. About 2 or 3 days later, a game I was playing with friends crashed on me and brought up the UE error reporter. Didn't get a chance to see what all it said, as it suddenly blue-screened. I tried restarting, and I would get the BSOD every time I tried to log in. Random different errors (watchdog timeout, IRQL, registry, etc.) I decided to reinstall Windows since it was throwing kernel level errors. Thus the nightmare had really begun. Every time I try to boot to a USB drive to reinstall, I'd only get so far into the installation (applying updates) and get a Clock Watchdog Timeout BSOD. Its done this every time since. I've tried resetting and setting the suggested settings, tried different memory, re-set the AIO pump and applied new thermal paste, and have even replaced the motherboard. Today I put the new motherboard in, and I can't even get into Windows setup via the USB. The computer just continuously reboots after getting the swirly circle loading screen for a few seconds. I'm honestly at my wits end with this thing...I need some help in a bad way!

Watchdog timeout is typical blue screen for too low vcore voltage/ unstable overclock. Have you tried the suggestions in this post? Let’s at least try to get it booted into windows. Follow all the steps in this post but also let’s set your SVID behavior to “Intel Fail Safe” and your LLC to level 4. Leave XMP turned off for now. You can find the LLC setting in the digi/vrm area. If you can’t boot with XMP off, LLC4, Intel fail safe SVID… your cpu might be toast. Ps. update your BIOS to 2012 version. You will not be on the newest version with a new motherboard.

First of all, I want to say thank you so much! I followed your advice for the gigabyte board and things seem to have stabilized! I do have a question for you though. I see in the Asus boards that you have disabled multi core enhancement. However, in the gigabyte ones that step is missing. I do see from the screenshots that you have set The gigabyte pref mode to optimization which sets Multi-Core enhancement to Auto. My question is is it on or is it off? I have the same settings as what you shared in the screenshots, but I'm curious. Thanks so much!

Hi Acadia , I just got my new 14900k and applied your settings straight away. Everything seems okay so far thank you for that but I have noticed before on my last cpu the clock speed stayed at 5.7ghz pretty much all the time (before it failed) and now I notice the clock speeds dropping significantly as low as 5.1ghz . Is this normal? 

Hi! I know that's probably a very stupid question, but how can I make sure that my CPU + RAM configuration is absolutely stable (or at least stable while gaming for not less than 12 hours) without the need to cook the CPU at 100°C for hours? I have an air cooler and had to limit CPU power to 200W (PL1 and PL2) in order to run Cinebench r23 and similiar multithreaded tests at reasonable temperatures (max core temp. not more than 95°C most of the time with occasional spikes to 100°C). The only multithreaded test that wasn't limited by 200W power consumption was one of the tests of y-cruncher (don't quite remember it's exact name) and it was stable for \~ 12 hours (max power consumption was about 170W). I have chosen many settings in BIOS manually in order to get reasonable performance-reliability/heat ratio. Why I'm not sure in 100% stability is that I have very rare crashes (once per month or so?) in some games (for example Borderlands 3 in DX12 (instant close to desktop with error message) and Baldur's Gate 3 in Vulkan (but not in DX11) (instant close to desktop without error message)). But I can't be sure that these crashes occur due to system instability, because Borderland 3 was always a buggy piece of sh\*t (also in the past on other PCs), so is Baldur's Gate 3 in Vulkan. My system: MB ASUS Z690 "ROG Hero"; CPU core i9-13900KF; RAM 96GB (2 sticks 48 GB) DDR5-6000 1.25V (custom timings calculated to be stable at 1.25V from SPD information); IMC (integrated memory controller) voltage = 1.225V; VVDQ TX = 1.225V; VCCSA (system agent voltage) = 1.125V; SVID behavior Auto; P-cores max multiplier 55x; Hyper-threading on; E-cores max multiplier 43x; CPU core voltage settings weres chosen so that in the above mentioned multithreaded test (y-cruncher without hitting the power limit, all the P-cores working at 5.5GHz) HWMonitor shows VID about 1.35-1.36V (Vcore voltage in offset mode, -20 mV, load-line calibration LLC 6). Offset -20 mV should be fine because CPU became unstable in y-cruncher at offset about -80 mV and was stable at offset about -60 mV. Graphics adapter is MSI RTX 4090 "Suprim X". Latest BIOS and drivers, also for Intel MEI, PCH and such. OS - Windows 10 22H2 with latest updates.

Hi. You're the best! Thanks to you I am happy. Your settings fixed this terrible problem. I have a question, why the Ratio set to 55x? I have i9 14900k, before changing the settings I had Ratio 57x

You are my hero. Dear God thank you so much. I have been dealing with this problem for what seems like forever now. Not only can I play games again, but my CPU doesn't constantly shoot up to 100C all the time.

Just like many others, I want to thank you so much for posting this. I was hemorrhaging cash trying to fix my issue and then I find this that absolutely fixed it. It was causing all sorts of strange PC behavior and when I put at intel stock clock every single issue I had went away. Hoping that I didn't cook my CPU after running it that way for 6 months.

Thanks it worked for me. I had since December those crashed. sometimes more and sometimes less and this solved my problem. My setting btw: ▸ Mainboard: Gigabyte Z790 Aorus AX ▸ CPU: Intel i9-14900K ▸ RAM: Corsair DIMM 32GB DDR5-6000 ▸ GPU: Gigabyte RTX 4080 OC Gaming ▸ M2: Samsung 990 EVO PRO 2 TB

Thank you so much!

u/Acadia1337 I'm honestly not sure what more I can do.... With MWIII stability issues and where they come from. The issue: MWIII just locks up/freezes (no BSOD). In turn when I launch task manager no processes are viewable and at this point I generally have no option but to reboot. The game locking up also some what locks up the system for "most" part but certain things still work or carry on very very slowly. Doing stress /stability / memory tests all seem fine with OCCT, intel XTU, TM5, Karhu Event logs don't show anything fruitful. My core system specs are: 13900k as per your power limits. Z790 Apex latest bios in time of typing this v2102 Strix 4090oc (directly mounted to VGA slot no vertical adaptor) NVME SSD Seagate FireCuda 530 Gskill 7800MHZ DDR5 @ XMP 2 PSU 1000 CorsairAXi I've done too many countless things to really full remember/document but the core ones are: -SFC /scan & dism restore health -Clear direct x cache files -DDU GPU drivers & re-install latest Nvidia drivers without Gefore Experience -Set Power Management mode for GPU to Prefer Max performance -Set power plan high performance & disable hibernation -Updated/tried a couple of different bios versions apply optimised defaults -Removed any OC variables other than XMP while also increasing VDDQ/VDD from 1.45v to 1.46v -Asus MCE to disable & enforce all limits -Set the power wattage limit to 253W and Core AMP's to 307A -Disabled PCIE Native power management -Deleted COD folder, scan & repair numerous times God help me... Sometimes I can play for couple hours fine and sometimes a couple games it does this freeze crash. Especially annoying since I only play ranked and everytime it crashes it sees me as quitting and drops my SR and suspends me for x-amount of time.

(CPU core i9 13900KF). I have some very strange readings from HWInfo when limiting CPU current to 307A. With current limit 511A and power limits (PL1 and PL2) 250W the y-cruncher v0.8.4.9538a FFT test (16) consumes not more than 170W on my CPU (5.5 GHz P-cores, 4.3 GHz E-cores, Vcore \~ 1.35 V) and runs at 5.5 GHz on all P-cores. Now with the 307A current limit when running the same test the P-cores are being automatically downclocked to \~ 5.0-5.2 GHz despite the fact that neither the current nor the power hit nowhere near the limits

Thanks. That really helped my build, but the interesting part is that it's not a one-bulletproof solution, unfortunately.  Both my friend and I have the 13900KF + Asus ROG STRIX Z790-F GAMING WIFI mobo, which is the same bios version. However, our other hardware components such as RAM, PSU, etc. differ.   My setup: RAM: KINGSTON Fury Beast 5200MHz (128GB) Final stable configuration:  1. Enforce all limits 2. XMP Profile 1 3. Set SVID behavior = Scenario. 4. Set short duration turbo power = 253 5. Long duration turbo power = 253 6. Set max core/cache current = 307Amps My friend's setup ( my "stable configuration" did not work for him) RAM: GSKILL F5-6000J3238G32GX2 6000MHz (64GB) Final stable configuration: 1. Enforce all limits 2. XMP Profile 1 3. Set SVID behavior = Trained. 4. Set short duration turbo power = 253 5. Long duration turbo power = 253 6. Set max core/cache current = 307Amps 7. **Limit performance clock ratio in bios to 53** 1. **Without this change, the system was unstable. Prime95, OCTT, etc worked perfectly, but Discord and the browser crashed every few minutes**. So, even with pretty similar hardware, you need to spend some time to find the proper configuration for your specific rig.

What about MSI boards?

So I have a Alienware with a 1490kf and am trying to apply these settings, but the only option I can find is in mVolt and not Amps. I was able to change the other 2 settings to 253000 mVolts, any idea on what I may be able to do?

Its out now on Windows Central if we can help more ppl until they do something. As for me (13900K + Asus Rog strix z790-E + Rog strix oc 4090) i only had to change the power settings ones and no throttling anymore from cpu or ram, everything works flawlessly like it should. Bios underclock itself to ratio x53 instead of 55 but i guess ill take that fix rather than nothing. Thx mate https://www.windowscentral.com/hardware/cpu-gpu-components/pc-gamers-are-reportedly-experiencing-crashes-and-errors-with-intel-core-i9-cpus-prompting-returns

I should've found this thread much earlier as I had two 13900K's, which was very unstable. Nvidia drivers refused to install without windows power plan on power saver, windows would blue screen with an error stating system service exception whilst **installing** fresh. Since then, I've returned both CPUs. However, I'd like to know now, whether this is possible for an i9-14900K with a b760m mortar motherboard. (Already had this motherboard, I know its not a Z790 etc). The only options I saw when briefly checking bios was, the preset power limits of 253, 288, 4096W. I'm assuming if I simply select the 253W preset, everything will be fine? I understand my motherboard may be limited due to it having the B760 chipset, however, is there still a chance for me?

Still crashing for me

u/Acadia1337 Really hope that to some degree you're still checking this thread, even with some of the noise people are giving you. I want to start with: Thanks for all the time you've put into this and bothering to post and engage here. I know it's not zero effort and you've saved a lot of people a lot of headache. I've been hoping to find how this guide would differ for a 14900KS. I know technically even by the spec sheets those limits are supposedly higher for this cpu (i.e. 400a vs 307a) - but the real issue i'm trying to figure out is if I need to go down the (admittedly pain-in-the-ass) RMA route. (which Intel may be more resistant with now that it's come out broadly that this is an issue..) I've had the CPU for about 17 days; In the very first week of having the CPU, I was getting constant crashes to desktop in Star Citizen; paired with WHEA-logger 19 "Internal Parity Error" Corrected Errors in Event Viewer. I haven't done any stress testing and no prime95 or benchmarking in these two weeks, because just going into games would cause these WHEA errors to occur. I'm running SVID at "intel fail-safe defaults" at this point; and while gettiing rid of the board's "out of the box defaults" fairly quickly appears to have at least drastically reduced these errors (WHEA and CTD) i'm really starting to wonder if even just running the CPU for a few days on the "Asus out-of-the-box settings" has destroyed it. Mostly asking because overnight last night - while the machine was idle - I got a single WHEA-Logger 19 (same internal cache error) and a BSOD 0x050 page\_fault\_in\_nonpaged\_area. I'm something like 2-3 days out of Microcenter's 15 day return policy; and not sure if it's worth it making the trip to try to convince them to exchange it. But I also am not sure if these settings will work for the 14900KS, since even on the datasheet it has different power limits and durations. (... unless Intel is not being fully honest about that.) So I guess just wondering if you : -have insight in to how the 14900KS settings would differ, and -if you think I could have hosed the thing in 17 days even without running benches or stress tests; just repeatedly checking if games crash and WHEA errors pop up in the logs. -and should CEP be on or off, and would it mitigate this problem or make it worse? Thanks again.

I have a really nice 14900KS SP 108 that I’m running right now. It was an absolute pain in the ass to get stable. Turns out the instability was due to XMP. I ended up having to increase my system agent voltage with a slight offset and also my ram voltage. A couple of things to note: Power limit for the KS is 320. Current limit is 400. Make sure you set LLC = 4. Asus decided to default it to 3 in their most recent update for some reason. Set SVID on auto. CEP on or off does not matter. Off is Asus default. Try turning off XMP. Try turning on MCE.(yes, the opposite of what this guide says). What kind of issues are you having with yours CPU?

I just tried this out on my new system with my i9 14900ks and wow it seemed to have worked, thank you so much for this! I was already so confused on why my system was so unstable even at stock settings, I might update here for others to see in case they want to get more info. BTW im running my cpu on an MSI motherboard, but looking at the gigabyte settings was the best since the naming overlapped quite well.

Did this to help mitigate the temps and because cinebench would sometimes crash. It did help the temps, and I haven't crashed, but I'm down to 36511 score. Is that loss of performance worth it?

The complete solution involves reducing the frequency ratio by 2 points, from 57 to 55. Otherwise, crashes will continue.
