Hello, I have 2 HD 6870 and trying to crossfire, they are both by XFX and same model, both working(fan's spinning) and cf bridge is on. When I go to Catalyst Control Center, and try to enable Crossfire, everytime I click on "Enable" and Apply, it jumps back to "Disable", and in GPU-Z, it shows both are working, 1 is on PCI-E 16x, 1 is PCI-E 2x, is this the problem? how do I fix this? thanks!

Crossfire Application Profiles are needed for crossfire.
