Re: Overclocking 6800 GT
The cvs version of Nvclock contains some basic nv40 support (mainly clock detection). Overclocking support will take some extra time as I need some debug info from windows to test my overclocking code. Further even GeforceFX support isn't done yet because of different 2d/3d clocks (and voltages/fanspeeds) but a workaround is in the make for that.
Expect some code the coming weeks as I will be on vacation next week.
