I have a dual EPYC 7742 system on Super Micro H11DSI-NT motherboard running Windows 2019 server, build 2004. Fairly often, I get random blue screens, all with the same error (recovered from minidump files, below). The offending driver is always the same: AMDPCore.sys. I'd really appreciate if anyone could provide any guidance with this.

 

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. 

....
Arguments:
Arg1: 000000000003fff0, memory referenced
Arg2: 00000000000000ff, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff8004bcd7fdd, address which referenced memory

....

 

SYMBOL_NAME: AMDPcore+7fdd

MODULE_NAME: AMDPcore

IMAGE_NAME: AMDPcore.sys

FAILURE_BUCKET_ID: AV_AMDPcore!unknown_function

FAILURE_ID_HASH: {e18f000c-8dde-0fe2-d02b-de5c86e5bf8a}

 

Thanks a lot!
