I want to ask if somebody know how it is with support for amd raven ridge with this motherboard.
To easy find that type of mb i mean: https://www.asrock.com/MB/AMD/AB350M/index.asp#BIOS

From what I see it's not recommend to update bios to 5.40+ version, but version 7.0+ doesn't have this restriction.

Please change my mind if it's just my misunderstanding.

Don't go higher than 5.40 since you won't be able to recover the bios and flash an old one if you do. They removed bristol ridge cpu micro code to make room for more zen 2 & 3 processors but I don't know why it also says raven, summit and pinnacle ridge too they don't explain but whatever, just don't take the chance and take it literally. If it is not recommended don't do it.

Bios updates are cumulative so everything that was done before is rolled into the newest package. I think, chalk it up to bad documentation.

They did not re-add bristol ridge support, right? So it's cumulative.

When i check the BIOS for SMU (the System Management Unit code block) v7.20 does have an SMU, v30.98.0, for Raven Ridge (2000 series APU's) so it appears it would support. (get Ryzen SMU Checker here)

But...is it worth it? Some things to consider:

After v5.40 AMD was adding and refining BIOS code for later processors (3000 and 5000 CPU's mainly as well as later APU generations) that's not going to help your 2000 series APU.

The LATEST (v7.20) will add some fixes for Windows 11, making it the most logical choice for updating, but is your processor even compatible with Win11? First gen CPU's are not and a 2000 series APU is based on 1st gen CPU. MS has an upgrade advisor utility you can run that informs you of everything that makes your system incompatible, including the processor.

The main thing they did (that I know of) is to make fTPM and Secure Boot enabled by default for Win11. You can enable them yourself to get the added security: just enable the security processor (fTPM) and disable CSM, then enable Secure Boot in your BIOS settings.

So, IMO, why risk it going beyond v5.40, for instance, even if it LOOKS like it should work. Are you trying to fix a known problem with system stability or performance?
