You have no worries updating the bios as it still supports your 2700x its older cpu's that's loose support due to size of the bios chip on the motherboard.What cpu do you have now, Wakadoo? I problem I read about was that updating to bios F50 or later caused the motherboard to no longer recognise chips earlier than the 3000 series. I'm currently on F31 with my 2700X, so a little cautious!
