nearcatch Posted November 30, 2022 Share Posted November 30, 2022 Experienced twice, diagnostics are from the most recent occurrence. I recently upgraded the CPU on this server.

jfoxwoosh Posted November 30, 2022 Share Posted November 30, 2022 This is very similar to what I had before. See here. What solved it for me was to change the cpu idle current setting in the bios. Quote Link to comment

nearcatch Posted December 11, 2022 Author Share Posted December 11, 2022 No luck, had another MCE today: Dec 10 09:59:27 UnraidServer kernel: vfio-pci 0000:08:00.0: vfio_ecap_init: hiding ecap 0x26@0x410 Dec 10 09:59:27 UnraidServer kernel: vfio-pci 0000:08:00.0: vfio_ecap_init: hiding ecap 0x27@0x440 Dec 10 13:19:10 UnraidServer kernel: mce: [Hardware Error]: Machine check events logged Dec 10 13:19:10 UnraidServer kernel: [Hardware Error]: Corrected error, no action required.

Squid Posted December 11, 2022 Share Posted December 11, 2022 One suggestion found via Google would be to run the memory at it's stock speed (2133) instead of underclocking it to 1866. Look in the BIOS for various settings. Quote Link to comment

Look in the BIOS for various settings. Does it say in the diagnostics somewhere that my memory is being underclocked? When I check System Profiler it says all the memory is 2666 MT/s, which matches the purchased sticks. Quote Link to comment
