My computer has a Gigabyte AB350 gaming 3 (v1.0) mainboard, with a Ryzen 3 1200 CPU. I was thinking about upgrade it to a 3rd generation Ryzen (if I can get one of those), but I fear having some BIOS issues.

According to Gigabyte supported CPU list, those CPUs are not supported by launch BIOS so I would need to update it. The thing is that my mainboard has Dual BIOS, and in case of BIOS failure old BIOS would be flashed into main one. So it is possible that (when equipped with a newer CPU) my BIOS could revert to a version that does not support it.

When flashing, there is an option to flash both main and backup BIOS but how can I know what version is actually flashed on both BIOS?

Gigabyte says that the "show info" option in BIOS shows both versions, but mine shows only main BIOS. CPU-Z and dmidecode also shows only main BIOS version.
