Kimber,
Stick with the BIOS for the A7V133, this is for the older A7V... From what I have read, the BIOS for the A7V133 offers more aggressive memory timing functions... Some users are flashing there older A7V's with the A7V133 BIOS, but it would be a step backwards for you to flash your newer board with a BIOS for an older board.
