I keep experiencing crashes with the following hardware:

cpu: intel i9 14900k
ram: gskill 7200 tried running xmp and xmp off still crashing
gpu: ASU’s 4090

I keep getting intermittent crashes and upon checking the error log it says pci express kernel error 41 can anyone direct me in the right direction? Also ran numerous benchmarks with xmp on and off and noticed that if I lower my p cores in xtu from x57 to x54 it tends to run the tests without crashing could it possibly be a bad cpu causing me issues?

What do you mean by "crash", can you elaborate? E.g. BSOD, CTD, black screen?

Black screen buddy and upon checking event viewer it says kernel error 41, read numerous posts online where people have had issues with these cpu’s and had to lower the performance core ratio from x57 to x54 which I think is silly why buy a chip that you have to downclock? Tried cinebench r15 and it crashes sometimes at stock ratios but when down clocked to x54 it works? Any ideas anyone or does it look like I have a faulty cpu

I’ve done that buddy that’s why I’m stumped exhausted most avenues I’m going to set the stock 253 power limit see if that changes anything incaste the cpu is pulling to much power causing the 12v to be unstable
 
1000watt gold rated ASU’s been fine for months only just started to happen done fresh install also. I’ve applied 253 power limits now to see how that goes

Error 41 is after the event. All it tells you is what you already know - as a result of the crash the PC did not shut down "gracefully". It is the errors before shutdown which count.
Instead of "try this", "try that", how about diagnosing the problem? Make sure that Windows is configured to produce a MEMORY.DMP file when it crashes. Then get WinDbg from the SDK and diagnose the dump. There is a good chance there will be something in the result which gives a strong indication as to the cause.

How do I configure it produce a memory.dmp when it happens buddy?

Been looking over the specs of the 14900k, it's effective boost clock is 5.6ghz, then boost 3.0 will let the chip go to 5.8ghz and finally thermal velocity boost will let 1/2 cores go to 6.0ghz.

I would say your chip is fine, problem is intel and AMD don't validate every chip to there max speed they can reach, as you say if many other owners have had to reduce the ratio to 54 to maintain stability, you effectively lost the silicone lottery.

I'm the same my 7950x will boost into the mid 5.6ghz region on 1/2 cores but never at its rated 5.7ghz boost it should do, like you I lost the silicone lottery as well as many many others have.

As long as your chip is inline or better than base frequency there isn't much you can do about it unless the CPU is faulty.

I’ve set the recommended power limit of 253watt and haven’t had any crashes yet so makes me think was it pulling to much power therefore causing it to get pci errors?

You could be on to something if the CPU wasn't stable at oob power settings it could have affected signal integrity between it and a dedicated GPU, though saying that and the behaviour you were getting is very similar to what I was getting, during your crashes before did you ever get in game messages like "pcie device removed, this happens if the GPU is disconnected" I had that plus loads of error 41's in event viewer on my old setup.

No buddy no error messages in game. Pc could be just sitting at desktop idle then black screen all fans hit 100% then check event viewer and it stated it was a kernel error. I don’t think I have an issue with my gpu or my memory. I have tried applying the power limits and since then seems to be stable
 
I’ve literally upgraded the motherboard good few months back I really seem to think it’s due to voltage causing it to be unstable. Do you think il loose a lot of performance by running it at stock wattage of 253?
 
Can’t really see it being the board as this is the second board I’ve had and as regards to the cpu I’ve posted to Intel support I’ve had nothing but headaches with this pc wish I stayed on console haha

Do you mean Intel failsafe? I don't know what tailgate would mean. As far as I know, SVID uses a table of frequencies and voltages and the CPU requests from the motherboard VRM what voltage it wants to receive at a given frequency. If you use Intel failsafe, I assume it just uses Intel defaults.


It is not uncommon to have overclocks that are stable without AVX and unstable with AVX.

Yer it doesn’t make sense to me as been fine for weeks and now just got this issue and as regards to running intels svid failsafe that puts 1.5vcore through the cpu which I don’t really want to be doing as it’s ran fine for weeks on 1.4 plus isn’t 1.5 a bit on the high side and will degrade the cpu faster?
