8800GT Voltage tweek?

[I Hunta x]

Ive seen there are some modded bios that allow voltage changes on the 8800gt but i was wondering if there is anyway to change the volts using something such as rivatuner?

Temps wont be an issue realy as im currently sat at 54C after 14 hours of folding on it at 30% fan speed.

Ive had the card stable at some ok OC speeds (1900 shader) but after i formated last the clocks became fairly unstable so i pulled back a bit, possably due to the beta drivers?

Should i/would it be worth me trying to bump the core/shaders up more again on the latest drivers?

Bit more incase it might be useful:

BFG 8800GT

Artic cooling Accelero twin turbo.

Core 700

Shader 1800

Memory 975

Drivers: what ever was the latest as of 16th dec 2010

Folding PPD @ stock 5000-5200

Edit: also what would be the best to test stability/artifacting? Furmark?

Also managed 760 core 1860 shader with a bit more of a play, seems alright so far any higher and i get artifacts using atitool/furmark so i think thats my limit ill let it run furmark for a few hours to see how it fairs in the long run, but i still would like more speed lol.

I use Furmark at 3 minutes with these settings: 1920x1200 and no AA.

I believe there is some sort of BIOS tweak that gives your 8800 more voltage, so you don't have to modify it externally, unless you want some more voltage (not advised for beginners).

Here is the flashing method for an extra .05v increase.

Also, the shader clocks will give you the most gains in folding, so if you can get higher clocks on the shaders and you have to lower the core, it is preferred.

I know the shaders do the most, its maxing out at 1860 regardless how i set the mem or core so i left the mem at the cards stock and i just left the core linked.

750 core

1850 shader

975 mem

16 1/2 hours folding temp 58C

Its gone up about 250-300 PPD from what ive seen, jumps around between 5200-5500 instead of 5000-5200

Got a few free hours today so ill try flashing it and seeing if i can get it up to around 1950 (hopefuly 2000ish shaders)

Cheers for the link BTW
