There is beta version of CH7 BIOS version 3103 made available to the community, but it's not an official release yet. Unless you have problems with your motherboard/BIOS, I wouldn't recommend updating to beta BIOSes.
Took them more then half a year.... but X470 prime-pro has an new bios (5601) ! At least it works stable compared to the former 5406 (126.96.36.199 AGESA) bios update. (With an Creative soundcard, and running memory with DOCP on 3200mhz.)
Haven't tested if all 4 memory modules work again, but have high hope that i finally can run 48gb of ram again without freezes !
