Feeling Stupid - RivaTuner Question

[dgunnoe]

I enabled the disables vertex/pixel shaders using RivaTuner. It worked well, no artifacts. I want to boost the core/memory clocks in the low level system tweaks, but they are grayed out. I can not check the box to enable the tweaks because the check box is grayed out. Do I need to install coolbits first or do I have to enable a setting in RivaTuner?

Don't think you can use Low Level overclocking. Use the driver overclocking in RivaTuner instead.

I have a PNY 6800 also (CompUSA deal). I did unlock all Pixel/Vertex shaders without any display problems. 3DMark results are below (core/memory):

325/700(all vertex/pixel shaders enabled - all following results the pipes are unlocked also)
3dMark05 3588
3dMark03 9877

400/700
3dMark05 4017
3dMark03 10856

400/760
3dMark05 4120
3dMark03 11175

400/770
3dMark05 4151
3dMark03 11206

I did not get any video glitches with any of these settings!

Not bad for under $220.00.
