Help me get more!

I have a 8800GTS 512MB G92 card and I currently have the gpu/shader/mem set to 684/1944/999. It is also water cooled and is running at a nice 34°C. I want to get more out of it so I need your help. Is it possible to increase the gpu voltage with a bios mod at all or do I have to go for a volt mod. I have to issues with soldering surface mount components as I do it as part of my job. Was just hoping for an easier method.

Nope, you'll have to solder to volt mod it.
