I guess the last 2 AGESA releases are almost only to solve the X3D CPU problems. If your PC was working fine before then I wouldn't change BIOS to the latest version as they made quick patches, so it can be a not fully tested version.
I saw some news that the last AGESA lowers maximum RAM frequency. I'm not sure if it's only related to SOC voltage as 1.3V should be more than enough for 6000+. Maybe there are some more changes.
