A user's virtual machines are crashing with a memory dump error that explicitly points to an AMD processor cache issue (AuthenticAMD.sys) on their dual EPYC 7452 CPUs.

The host is a Dell PowerEdge R6525 with 2 AMD EPYC 7452 and 512GB of RAM. The host shows correctable and uncorrectable memory errors. The VM's memory dump shows a 0x124_0_AuthenticAMD_PROCESSOR_CACHE_IMAGE_AuthenticAMD.sys.\n\nI have run the Dell diagnostics, windows memory test, and Memtest86. Non of them find any issues. The idrac does not have any uncorrectable memory errors in the logs. The issue stated after I installed Hyper-V and tried to run some test machines. I have adjusted the processors to NUMA Nodes per socket of 4 and L3 cache as NUMA domain as enabled. This seems to have helped as they crash less often but they still crash. All drivers are up to date and all windows updates have been applied. Is there anything else I can look at to fix this?",
