BIOS 10.02 is confirmed working. It also brings AVX-512 support back on those CPUs that still have it via a Microcode switch upon selection of AVX-512. The microcode switch is all automatic, pretty neat feature from Asrock, wish my Hero board did this.

BIOS 11.01 (which supports Intel next gen) seems to be bugged and is not working even though the options are all still there. I could try and reflash to make sure, but I'm happy with 10.02.
** BIOS 3.03, 4.02, 5.02 (out of box) all DO NOT WORK. If you attempt to select a BCLK higher than 102.7 it automatically reverts to 102.7. Also the Non-K BCLK option is not in the BIOS. BIOS version between 5.02 and 10.02 might work, I just never tested them as I decided to go straight to the newest versions.
