In all benchmarks and CCC it only shows 1 gpu out of 2 working. The other looks underclocked, and does not seem to process data. Trying afterburner, and furmark. using latest drivers 10.2
What do you mean it only shows 1 out of 2?
There should be a drop down menu to select which card.
If you use 3DMark Vantage you could compare your score.
