Hi guys , I just ran some tests on my new 4870x2 and fitted a 4870 for tri-fire but my pc will not boot with the 4870 installed , I get cmos error code shown on the lcd poster , has anyone else seen anything like this ? I have had this vid card in this pc before , and the pc will boot with either vid card on its own.

This vid card has been flashed with the modded bios , could this be upsetting things ? Or would they just dislike cf if that was the case ?

Any help would be greatly appreciated.
