You can buy a BIOS chip and replace the board's one (it's on socket) http://www.ebay.com/itm/BIOS-Chip-ASROCK-970-EXTREME3-/380449339308
But I would wait for the board and check the BIOS. If P1.50 or newer, the CPU is supported.
tnx for ur answer i hope my mobo come with the version u mention coz i dont whant to wait again for the chip
and olso i dont have so much faith in bios updates,i hear alot even from profesional pc builders and after bios updates boards go to hell w/o reason..
