Whea errors on windows 10

IziXplD · Dec 12, 2016

Hello,

I'm new to the forum so I hope I'm posting in the correct section.

Configuration :
ASUS P8Z77-V PRO
i7 Ivy Bridge 3770K (not overclocked)

Since 2 weeks now, I have multiple WHEA errors. I thought it was due to my graphical card driver so I came back to an old one (one that I had when I didn't have this problem), but nothing changed. I tried to reinstall windows 10, but nothing changed. I tried to update my BIOS in the latest version and... nothing changed. I'm trying to find solutions online but I can't find a proper one. Almost all of them talk about AVG or Avast causing the problems but I use windows defender.

The only solution I found was when I tried running a stress test of my CPU with Prime95. I left if run all the afternoon while I was playing without noticing it and I had no crash. I stopped it and ... crash, almost instantly. Since I have to keep Prime95 running but it keeps my CPU at 100% so I guess it's not very good for it

I debugged the minidump files and had multiple bugcheck 124 with "Probably caused by : GenuineIntel" with this (the 3 last dump) :

Code:

Section 0     : Processor Generic
------------------------------------
Error Type    : Cache error

Section 1     : x86/x64 Processor Specific

Code:

Code:

Section 2     : x86/x64 MCA
------------------------------------
Error         : GCACHEL2_EVICT_ERR (Proc 1 Bank 8)

It's clear that it's my cache level 2 and from what I read, it means that my CPU has a default. I'm would like to know if you had another idea before I change it (and to be sure that the problem will disappear if I change it :smile

Thank you

Hi. . .

0x124 WHEA (Windows Hardware Error Architecture) are notoriously difficult to solve as they involve unknown hardware failure. 0x124 = machine check exception.

If you have an Intel CPU, you can run this diagnostic test - https://www.sysnative.com/forums/ha...e-tutorials/3908-prime95-hardware-stress-testing-intel-cpu-test.html#post145238

If AMD, it may work anyway.

Thanks for your answer.

I know that it's a machine check exception and with the dump you can see that it's coming from L2 Cache but I'd like to know if the only solution is to change the CPU or if it will be useless.

I already run the intel diagnostic test and everything was fine

Ok so it seems to be working now.

I found that speedstep (an option on the CPU which makes the CPU go into "idle" mode) was part of the issue. I disabled it and I did not get any crashes for 30m. So I put it back and boosted my CPU voltage from 1.008v to 1.060v and now it works well. No crash so far.

Thanks for your help jcgriff2
