Ah okay, no clue why, but there is a mismatch in comparison to the current microcode revision but it doesn’t seem to be related as I’ve got a different CPU model.
Anyway:
Machine:
Type: Desktop Mobo: ASRock model: X570 Taichi serial: <superuser required>
UEFI: American Megatrends v: P4.80 date: 02/16/2022
You’ve got the latest microcode. But the BIOS you’re using seems to be quite old.
