just bought a 7870 to go along with my 7870.
googled around and saw most people can add a second card for crossfire without adding drivers, but when I did, my 3DMark score dropped 3000 points. Reinstalled the drivers, enabled crossfire again, and lost 100 points in 3DMark.
Open up BF4, and as soon as the game starts to load a map, I crash with a "Battlefield 4 has failed to respond" or whatever.
If I disable Crossfire I can play BF4 fine and my 3DMark score stays within 100-200 points of the Crossfire score.
Yes, I have the bridge installed, yes the power cable is hooked up.
Someone suggested to synchronize clocks, disable ULPS and force contrast voltage and it didn't help. Tried 13.12 drivers and 14.2 and same exact issue.
Buh?
