HD 7990 dual GPU card. 2nd GPU disabled.

Question asked by rhettski on Jun 29, 2016

Hello all,

I've been having trouble with my HD 7990 card for some time now. The only way I can get both GPU's to run while gaming is by using very old drivers(13.9). I have no option with the latest driver (Crimson 16.3.1) to activate crossfire and it says the 2nd GPU is disabled. I use Afterburn which gives the option for in game monitoring of your graphics card performance. Whilst gaming in Battlefield 4 the 2nd GPU isn't doing anything.

I have checked the registry, and crossfire is enabled. How can I get the 2nd GPU to become active?

Help appreciated.
