    rx 480 wont crossfire


      Just today I went and got 2 rx 480s and after setting them up and making sure they both work individually, I cannot get them to crossfire... I did notice that in my radeon settings one says (Primary) and the other says (disabled) When i go to the global settings the crossfire option is disabled, so when I go to enable it the screen goes black, and then radeon settings doesnt pick up the radeon cards, but they still appear in my device manager as 2 rx 480s. When the monitor comes on again it uses the on board graphics, which I believe is windows basic display driver. Any idea why crossfire wont start?


      My system Specs:


      MOBO: MSI Z97 Gaming 5

      Processor: Intel core i7 4790k

      GPU: 2 rx 480

      16 gb ram

      and a 750 w power supply !
