    Crossfire R9 290 lower FPS

    subliimaze

      Hi,

       

      I have two R9 290


      Card 1:  Saphire Radeon Reference card R9 290

      Card 2: Power Color R9 290

       

      CPU: A10-78070k

      RAM: G-Skill 16gb 2400mhz

      MB: Gigabyte GA-F2A88X-D3H

      PSU: Corsair AX860i

       

      If I am using just 1 card, all my games run great, high FPS etc (example:  Guildwars 2 runs at 80fps with a single card, doesnt matter which one).

       

      If I run both cards in crossfire, i drop by 20-60 fps in all games.


      I have read through these forums, tried everything that has been suggested, reinstalled/uninstalled with DDU with no change.

       

      Any help would be greatly appreciated as I do not know what else to do.
