What BIOS version does it come with?

According to the bios page for this item.....AMD AGESA Combo-AM4 V2 1.1.0.0

Will this Mb support my 4x16Gb DDR4 3200Mhz system RAM? I looked on the ASRock site and it is very vague... Thanks in advance.

Yes it does. I own this motherboard. I have 4x 8Gb ddr4 corsair vengeance 3600Mhz. But this mb is rated max 3200Mhz. But it will use only 3200 out of 3600Mhz.
