yep iv tried everything, the newest bios version for this board which is the one I was trying to update to, apparently its only compatable with the b3 revision boards, mine was a old b2. iv read up theres been quite a lot of people have this problem, the people with the p67a-gd55 like me who have a b2 and try to update, they have had it because its not got a dual bios, the gd65 etc upwards do have a dual bios so they can switch back to the other one. there are quite a few complaints that it doesn't state that it doesn't work with the b2 and peoples motherboards being borked because of this.
ah well nee bother iv ordered my self a z77a-gd65. had enough of that old motherboard anyway was nothing but a pain. overclocking etc was fantastic and flawless but because it was a old b2 board the sata ports stopped working etc, so it can go and sit in the naughty cupboard now with all the other broken parts lol.
