i'm using inno3d 6600 vanilla running at core/mem 300/500. To oc this gc i'm using the latest rivatuner but it seem that i cannot push above core/mem 450/570 due to rivatuner limitation. I'm been do some reseach and found there are a way to exceed this limitation by adjusting setting in power user setting but dunno how.

so anybody here that can help me . thanks
