3.71A bios, uses the V1 AGESA 1.0.0.8 from 22/02/2022, but does not have 4000/5000 support like some of the earlier beta bios and x300 bios do. But it is the newest bios version if you have a 3000 chip or below and what I've been running on my 3200g.
I've just got in contact with Asrock about a new bios as due to the vulnerabilities listed in the latest AMD security bulletin:
AMD Processor Vulnerabilities
They said it dosn't apply to me as the security bulletin calls it a '3000 series athlon processor with radeon graphics', and the 3200g processor is ryzen not athlon.
But I'm not too sure and just think their wording is off and it applies to both the ryzen and athlon 3000 series as I think an athlon is just a cut down version of the ryzen chips, I don't know if anyone knows better and can weigh in as I highly doubt the latest a300 bios we got is covering the latest security vulnerabilities.
Anyway, they did give me a new beta bios 3.70e which they say is using v2 1.2.0.7 which I will upload a post shortly, and I hope someone here is able to test it for me, as I can't recover from a bricked BIOS and this is my daily PC.
