    HD5970 crossfire not working


      Crossfire is not working anymore for me and I can't figure out what's going on.

      In GPU-Z it says "AMD CrossFire: Disabled".

      In CCC I see a "Disabled Adapter" (?!) and no mention of crossfire in the game setting. The Catalyst TaskIcon context menu does not show any crossfire option.


      So, in a nutshell, to me it seems the second GPU is simply disabled. I'm not aware I did this on purpose. How can I enable it again?


      Currently in e.g. FarCry3 I get 30FPS, same in Arma 3. But I know that in both games I can get almost twice as much FPS; I've played FC3 with steady 60 FPS and gorgeous settings.



      • WXP 7 Pro 64-bit
      • Intel Core i7-980
      • XFX Radeon HD 5970 Black Edition
      • be quiet Dark Power Pro P8 1200W ATX 2.3


      Thanks for any help!
