Im running a MSI Cyclone OC 6580 with a Sapphire 6850 as its slave. Both in Afterburner and GPU-Z it reports that both cards at running and crossfire is working fine. However, the slave card is said to be operating at 775/1000 and the MSI card is OC to 870/1120. I have Afterburner set to sync settings for both GPUs, but its not overclocking the Sapphire card. And I cant use Sapphire Trixx Utility because now its just crashes everytime I try to load it. IS there any other software that would let me set the slave clock speed to the master?
