So i have the geforce 7950 gx2, and i'm overclocking with rivatuner. Basically i've overclocked the core clock to 607 mhz and the memory clock is maxed out at 800... is there a way to force it to overclock more than the max 800? would it help?

thanks for your input, appreciate it

The only thing I could think of with RivaTuner specifically would be to first, ensure that those OCs are completely stable, then flash the card with a modified BIOS, and have RivaTuner detect the new "default" clocks. I would try another program, though if you can't find an easier fix for RT.

i think there's a rt setting that allows you to do that.
