Picked up my brother's new PC today and installed stuff, etc. but I cannot get his two Sapphire 6870's to work.
The Catalyst Control Center doesn't show an option for crossfire, but it does pick up the two cards, it says one is the primary adapter and the other one is disabled. Windows device control also picks up two cards. The second card doesn't show up in HWMonitor, but it does in cpu-z... I've tried installing new drivers, rebooting, deleting them, rebooting, installing again, rebooting but I just cannot get the crossfire option to show in the CCC.
2x Sapphire Radeon 6870 1GB
i5-2500k (not overclocked yet)
8GB Corsair Vengeance 1600MHz
Asus P8P67 (no suffixes)
120GB Intel 320 series SSD
WD 320GB Caviar Blue HDD (which doesn't show up by the way, I'll have to check cables)
Could it be because I didn't fit the bridge correctly? Like I didn't push it far enough in?
