Hello - I bought this board a month ago with BIOS 3.20 . The 3600 should run without problems. From BIOS 2.30 - it says on the mainboard which BIOS is installed.
There are only a few CPUs that are not recognised correctly. If you buy new, no problem. 98 % of the processors run from this BIOS 3.20 - Here the link - https://www.asrock.com/mb... - Greetings Werner
