Am I just really unlucky with my 6970s?

post #1 of 4
Thread Starter 
Ok, so I have two 6970s in crossfire (Sapphire and XFX) and I can't seem to overclock either one of them at all. They're even crashing at 900 MHz core clock and 1375 memory, so thats only a 20 MHz on core only. I've tried increasing voltage and I still can't get it stable at those clocks. Is it possible I'm doing something wrong, or did I just get really unlucky? Any help is appreciated, I feel like I'm losing out on what could be better performance. Thanks guys:thumb:

Take a card out and then try overclocking?

strange issue. Voltage should at least slightly influence the overclock. Might be drivers, or maybe its just one of those questionable things where taking out the gpus and putting them back in fixes it tongue.gif

Do you think running Eyefinity could influence the OC ability?
