The latest bios is good indeed, I asked the salesperson to flash it to the latest one when I got the board, which is v1A. It would still throw a CPU Error on boot, but when I almost lost hope, it booted correctly on the 4th attempt. Now there aren't any issues at all, but the only options I did in the bios were to enable virtualization and A-XMP. I read the horror stories at r/msi_gaming and was ready to return the board.
There's a new beta bios from a few days ago, but I won't bother with it. It's definitely not a board I'd recommend for beginner PC builders.
