Hi,

I use guiminer, and run both cards at an intensity of 17. I am getting 430khash on each. However if you put the intensity up to 20. Then you will get a higher khash. I just dont like putting cards under to much load.

When I get home from work tonight I will put the intensity up higher to see what he higest hashrates are and will take a pic.

Im pretty sure you can get 460 - 470 though.

Thanks.
