what does AMD AGESA 1.0.0.3A due for threadripper?

[terroralpha]

hello,

i can't figure out what the new microcode does for threadripper. i have several system here running 3970X and it seems to be working. motherboards are from several vendors. i see that they all got new BIOS version saying that the AGESA is now 1.0.0.3A, but no patch notes saying what it is that the new microcode does. checked other vendors, no release notes either. when i google it, i get results about 1003ABB and ABBA, which is for ryzen.

i want to stay up to date but don't want to create problems. anyone know where i can find actual documentation for this?

thanks

AMD seems to be quite bad at releasing AGESA changes, so unless the motherboard makers spill the beans, it's hard to know. To my knowledge, they don't even divulge all the changes to the board makers.
ABB and ABBA is for regular Ryzen and are old now.
AGESA's tend to only improve things, not cause problems, at least not as long as the board makers didn't screw up.
On "regular" Ryzen it was a huge improvement moving from the early releases to 1.0.0.4B.
You should also be able to "roll back" unless it specifically states that you can't go back from a specific release.

I figured.
I checked the bios info the ASUS zenith ii extreme, and the notes for the BIOS that updates Agesa to this version also say “performance improvement”. But that might be just ASUS related. Aside from that, nothing.

I’ll try this microcode on 2 of our workstations and see how it pans out.
Thanks.
