Hi Everyone. I am having WHEA-Logger Event ID 18 (By component: Processor core, Error Source: Machine Check Exception, Error Type: Cache Hierarchy Error)
Is this a hardware failure of some sort or just windows software/drivers issue? How do I identify what part is causing problems. I don't have any spare PC to test into.
Apparently this is happening a lot to people. Searching the web you will find lots of different fixes. However most the time on the ones I have seen where it is a ryzen cpu with a nvidia gpu the users report back saying it ended up being a cpu replacement that fixed it. That doesn't mean it is your issue.
I found a couple good threads that have many people talking about the issue and what they have tried. Maybe it will help you.
Your mother board support department can also be a good tool for helping isolate what they think the issue might be.
Those thread links:
Try the RAMs with 3200. Restart, freeze and WHEA errors have different causes. Your RAMs may be causing the freezing problem (and WHEA error). Obviously you are having a restart problem, if this problem is evident on the desktop, return the motherboard immediately.
Yes. I had seen many issues too over reddit as well. So should I RMA my CPU? Also is this causing the prime95 issues as well? I conctacted AMD Tech support and they too told me to RMA the CPU. Should I proceed or try to rule out any other part? I have done memtest and also OCCT Stability test. Memtest cleared with 4 passes with XMP On and OCCT Stability test of over an hour gave no errors.
I think you have done all you can. While in general these issues can be caused by a host of different issues non cpu related. There has been what I would call an abnormal amount of these issues being caused by the cpus as of late. So if AMD is willing to RMA, I would let them. They likely would not offer if they too didn't think it is a good possibility it is the issue. So I would do it and go from there.
i agree with mstfbsrn980 ... on ryzen oc ram over 3200 seem to raise this kind of issues (the restart without bsod , i was having the same problem with 4400 sticks only running at 3600 , the problem is not the sticks it's the oc applied to the system when going beyond 3200)
Which again is why it could point to a CPU issue. The memory controller is in the CPU.
Again it is not really possible to know for sure what is causing the issue as it is such a vague error that many things can trigger it.
ryzen recommanded ram speed : 3200 mhz ... nothing more to say ... the rest is about overclocking and your understanding or not of overclocing
