BSOD irql not less or equal, AMDppm.sys

I need to disagree with some of that. The dumps (ALL the dumps) very strongly suggest a bit flip during amdppm.sys execution. All dumps either occur on logical processor 8 or 9, so that would be core 4.

Whilst there is no concrete evidence - and there is unlikely to ever be concrete evidence - the circumstantial evidence that this is a CPU issue is extremely strong. In addition there is no evidence that the problem lies anywhere else.

Hi

In Verifier I checked the boxes for; I/O verification, Force pending I/O requests, IRP logging.

I chose every driver that was not Microsoft related.

I did not see anything about logs so I thought it was gone after closing CMD, but after reading some more I belive the logs are located in C:\Windows\MEMORY.DMP? If someone will confirm I can upload that to the post? Or it may be included in the V2 log?

Latest V2 log collector file.

DESKTOP-10PKS30-(2023-07-01_18-17-01)

Note that there were some different BSOD after disabling C-States so that setting were set back to auto.

I do not have access to another CPU to swap test.

Thanks,
Ekw

Make a new restore point.

Run WDV with these customized tests

Code:

    
    [ ] 0x00000001 Special pool.
    [ ] 0x00000002 Force IRQL checking.
    [ ] 0x00000008 Pool tracking.
    [ ] 0x00000010 I/O verification.
    [ ] 0x00000020 Deadlock detection.
    [ ] 0x00000080 DMA checking.
    [ ] 0x00000100 Security checks.
    [ ] 0x00000800 Miscellaneous checks.
    [ ] 0x00020000 DDI compliance checking.
    [ ] 0x00080000 DDI compliance checking (additional).
    [ ] 0x00000200 Force pending I/O requests.
    [ ] 0x00000400 IRP logging.

If there is no immediate BSOD then post a share link displaying results of administrative command prompt
verifier /querysettings


For any BSOD post a new V2 share link into the newest post.

Report any major performance problems including very slow boot.

There will be additional customized tests.

If WDV debugging reports no misbehaving drivers then focus or malfunctioning hardware.

See if you can find a friend neighbor, relative, or local computer store to swap test components.

If you're unable to swap test then find a vendor that has an acceptable return policy.

FWIW the two dumps on the 1st July were identical in all respects to the ones we've seen already.

Hi again

Did contact the store were I bought the CPU at release, and they did send me a new one without any hassle. Been using it for a couple of days now without any problems.

Thank you all for troubleshooting and helping.

Glad you got it sorted.
