Based on the 7800????? :lol: :lol: :lol:
6800GS is NV40 bud, and I have quite a bit of experience unlocking them.
The pipelines and vertex shaders are bitmased. Download, install and run Rivatuner if you want to unlock them.
Then open up Rivatuner and click on the customize tab, and then proceed to the NVstrap at the top. At the bottom of the opened window click on "install" which basically then gives you the option of advanced hardware configuration.
If you click on the box thats "hardware masked units" your going to get a warning box, by clicking 'Yes', you can select custom and a a PP/vertex box will then appear.
You'll see the active units, indicated by a check mark. Then you'll see other's without checks, however in the dialog boxes to the right the state will be "disabled" and HW masked will be marked "yes".
Basically you need to click on the grey area to allow the unlock. After you've selected the bitmasked units, hit ok then apply....save and restart your machine.
When you boot back up and there's no corruption, go back into Rivatuner to confirm that you've unlocked to full spec (16x1 5vp) It will say in a sutble line right in the first dialog box. That should about do it. This is from memory, so if anybody finds that I missed something (dont think I did :lol: :lol: :lol: ) then let me know.
