I have two HD7870 cards in crossfire mode and GPUZ shows that they can run at X16 3.0 but are only running at X8 1.1 I'm not sure what to look for in the bios to change the BUS interface. The MB is a Sabertooth Z77. Any information or advice would sure be appreciated. And maybe some overclocking advice????
