R9 270x Crossfire Issue

Dykstra · Aug 1, 2014

So I have 2 XFX r9 270x on sale intending to crossfire them, but in catalyst the crossfire option is grey saying my crossfire bridge isn't connected properly. Heres a screenshot

So I try 3 different bridges and they all do the same. Still thinking it might be the bridge I buy a new bridge and I still get this error. Windows recognizes both cards and so does gpuz links here

Have you tried uninstalling/reinstalling the gfx driver? Unless one of the cards is defective, I don't see how the bridge could be the issue.

clutchc :

Multiple times. I have tested both cards individually both are working properly.

Then I would have to assume one of the cards has a defective bridge connector or possibly a malfunction in it that is not allowing CF to be enabled. Try leaving the bridge off and see if the option to enable CF is still greyed out.

Tried and it still wont let me enable crossfire, I am stumped.

Edit- Tested 2 660s in SLI and it worked flawlessly. Just need to get my 2 cards working now.
