Please add Vermeer microcode to DB, not sure which 1 it is exactly, this is the extract from MSIā€™s B550 that has it.

Think itā€™s cpu00A20F10_ver0A201009_2020-08-21_D955D32A.bin

There is nothing new



Any reason why my b350 doesnā€™t show available microcode for vermeer / cpu00A20F10_ver0A201009_2020-08-21_D955D32A while being an AM4 socket?

What does the microcode repository have to do with what your OEM BIOS includes? You need to ask your OEM if you think something is not supported.

I am looking for the oldest uCode for A0652 cpu, that is a commet lake cpu. I have found C2 uCode in a old bios from my laptops support page but is there any older?

Build 20251.1 restore the microcode D6, does that mean than the DE was buggy and didnā€™t pass the tests?

539

It could mean anything.

Microsoft for example has rolled back to:
cpu506C9_plat03_ver00000032_2018-05-11
for like a year now but the OFFICIAL Intel microcode release for Linux has it:
cpu506C9_plat03_ver00000038_2019-01-15

So why should Intel distribute the newer one for over a year now if it was buggy, but Microsoft not - there is no clear reasoning.
