Using GPU-Z to monitor, running Sapphire Trixx to OC.
I have a Sapphire Dirt3 HD 6950 2GB on a Gigabyte P67X-UD3-B3 motherboard. I have overclocked it to 880/1375 @ 1.13V and it's stable. Now randomly my GPU downclocks to 725/1250 and I have to reset my overclock in Trixx and then re-apply it to get it to run again. Does anybody know what the problem is?
