Anyone have any luck with specifically the b450 tomahawk max? CSM = OFF - Updated vbios updated driver, resize on in bios, PX1 shows it all fine. But the "check with motherboard" line is up on PX1 and Nvid control panel shows resize off, and device manager shows no new long range line like it should. Anyone else not having it enable? GPU is the xc3 ultra 3070 cpu 5600x but I dont think that should matter much which model 30 series card it is.

     Yes the 2 are tied together, pretty sure most every mobo they tie together as well.

    Alright figured it out, incase others come wondering. Rebar is on first b450 amd 5000 update from 11/30 but it wont work, theres a newer i think around 2/30 rebar update and optimization bios for the 450 toma max, once that version of bios is updated it'll finally work.

    My x299 FTW K has all those options separated, the only option for REBAR that changes one of the required settings is setting REBAR on which throws up a prompt that CSM will be disabled. I had to manually turn on Above 4G Decoding.

    Glad that you figured out that an newer BIOS update fixes it.
