Hello,
Unfortunetly Rivatuner had the same problem. I would select overclocked frequencies, test them and apply. Click ok and go back to the screen and clock speeds are at default again.
I googled some stuff and in this review found:
"We found that Far Cry was still perfectly playable at the Gen 2's native 1,920 x 1,200 resolution, with quality settings on maximum. However, The Chronicles of Riddick was a little jerkier using the Shader Model 2.0 settings, averaging 28.7fps, but dropping to 19fps at some points. It was totally unplayable using the Shader Model 2.0++ mode. This is nothing that a little GPU overclocking can't take care of, we thought, but unfortunately the Gen 2 didn't play ball. The Coolbits 2 auto-detection routine wouldn't overclock above the stock frequencies, and manually increasing the clock speeds only made the Gen 2 unstable. It's worth noting that the 3D module isn't user-upgradable, either."
There must be some way around this problem, and you guys def have a lot more experience with stuff like this than I do. I am hoping there is some sort of solution here.
Again, any help is greatly appreciated.
