    Crossfire Stability - ROG Strix 480 & XFX 480 Black

      Hello,

       

      After spending some time trying to find a second ROG Strix 480, I got a second 480, but from XFX.

      System:

      Windows as all updates.
      All Drivers also fully updated.

       

       

      Got home, configured everything, tested here and there and things were pretty stable, although I wasn't too happy with the 3DMark score.

      - Drivers: Previous Stable ones.

      Decided to download this morning the driver update directly from AMD, to fix the Validation Warning from 3DMark and to my surprise the score dropped to 4.9k

      Crossfire working, I see the load hitting somewhat evenly both GPUs, but the memory clock on the second GPU(XFX Black Edition) didn't get past 600Mhz.

       

      It's the first time I'm doing a Crossfire, so I'm pretty sure I'm doing something wrong.

       

      Can anyone point me in the right direction?

       

      Thank you.
