first thing, this was done on a BFG Geforce 6800 OC. No problems whatsoever.
Steps to unlocking Pixel Pipes and Vertex Pipes
1. Download Rivatuner (dont know if I can tell you where so search for it)
2. Install Rivatuner (i know, dumb step, but you never know)
3. Open Rivatuner (another dumb step, this is my first tutorial smile.gif )
4. Wait for it to do all the initialization and what not.
5. When it opens you will see your card and monitor in a box, just below that box you will see something like this. 256-bit NV40 (A1, 12x1,5vp) with 128mb DDR. This is the line that will tell you if you have unlocked either of the pipes. Obviously the 12 there is the pixel pipes, and the 5 is the vertex pipes. (Glad you opened the topic, I reformatted and lost my 6th vertex pipe, gotta reset it, thanks)
6. Click the little arror on the right side of that text and click on the first icon you see. Should look like a little graphics card.
7. Next click on NV Strap driver, and on the bottom click install.
8. After this you have to check the box that says "Allow enabling hardware masked unites" IT WILL NOT WORK IF YOU DONT DO THIS!!!
9. Right above that it says "Active pixel/vertex units config" and the box to the right says something, change it to custom.
10. Click the customize button below it.
11. Now you will see where it says Pixel Pipes and Vertex Pipes. Some of them say "yes" under HW Mask(hardware mask, the ones that are hidden and not unlocked.)
12. So once you find the 2 you want to try to unlock. Click where all the checkmarks on, on the line of the one you want to unlock.
I believe the pixel pipes work in 4 per unit. So I have 3 unlocked=12 pipes, you unlock the other one you should get 16pipes. And the vertex one is easy, its just 1. Then you have to restart your computer and test it. I used AM3 and you could easily tell if there was a problem. Hope this helps and good luck smile.gif
****I DO NOT GUARENTEE THIS WILL NOT FRY YOUR CARD, I HAD NOT ONE SINGLE PROBLEM DOING IT, ALL I HAD TO DO WHEN I SAW ARTIFACTING WAS GO BACK TO RIVATUNER AND UNCHECK THEM AND RESTART****
