Hi, I am attempting to overclock my gigabyte 7950's in crossfire (which I hear overclock like a beast). Every time I move the slider for the frequency up even a little bit I have stability problems and no game will play. I tried raising the voltage a little as well with no luck. so I have two questions:
1. Is it possible to overclock in crossfire mode and if so what am I doing wrong?
2. What is a surefire test to make sure a graphics card isn't faulty?
* I forgot to add that my PSU is a Corsair HX 1050 watt, CPU is a i5 2500k oc'd to 4.5 ghz, and mobo is an asrock prof fatality gen 3.
Well I'm waiting for my new parts to come in as my ram started to go bad randomly but I like to overclock just to try it out and heard that the 7950's were good at it. Anyways they were getting lower than normal FPS in the Just Cause 2 benchmark (dark tower) averaging only 40 fps which is much lower than 2 7950'd should have....
