I've been struggling with an increasing number of WHEA Event ID 20 errors on this new build. Completely stock (no OC). I've tested the ram and stress tested CPU and everything is stable for the past couple days, but I can't understand what these WHEA errors relate to. I even swapped out the stick of rams with no success. Ram is 5600mhz Corsair Platinum CL 36.
I've flashed the bios to 2103 and updated all the ME firmware and drivers and installed all available updates in Armoury Crate. I've rank chkdsk /r and sfc scannow. No issues. Memtest no issues. I've reset windows 11 completely and reinstalled HWINFO and installed all Windows 11 updates.
As of now I have probably 23 WHEA errors (Event ID 20) since restarting 15 minutes ago. HWINFO shows 23 total errors and 1 PCI/PCI Bus Error
Anyway to diagnose this Event ID 20? Do I have a defective CPU? Or is this a common WHEA error that I should ignore?
