I tested the bios and so far the only issue I had was when I put in all my usual options including undervolting and stuff, that the mobo restarded and turned up with a 00 code. But a restart of the system then made it work, whereas the previous and in the meantime removed bios 906 and 1002 (I believe it was) wouldn't start at all when changing options in the bios until I reflashed the same bios again.
