[SOLVED] Crossfire disables dynamic clocks help! EDIT: Solved query on PCI E swap [can install one GPU in second or third PCI E slot, with monitor plugged into that graphics card. Boot system(will be black screen until Windows loads), then turn off system. Install second GPU in first PCI E slot and boot system. CCC should show primary adapter/card one as the GPU in second or third PCI E slot. Then enable Crossfire and reboot once more. If you need to see post/boot, need to plug a monitor into the other card. EDIT 2 : Dynamic clocks do not work in Crossfire mode sadly. Thanks
