Mismatched crossfire

post #1 of 4
Thread Starter 
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?

Have you set MSI Afterburner to overclock similar GPU's in the settings menu?

Yup, and the sapphire card will not clock to 870/1100. I tried switching the cards so I could use Sapphire trixx to overclock the sapphire card. But now crossfire doesnt work. Ran driver sweeper and did a fresh install of CCC but nothing.... only one card works now.....

With the MSI card as slave, when I start Kombuster or any stress test program, it will clock up from 100/150 to 775/1000. But I will get no GPU load and then it clocks back to 100/150
