I figured out the vmods for gf2 ultras so i'm sharing them with you.
I wouldn't set the vgpu a lot higher than 2.4v on watercooling, because these cards get very hot. The vgpu VR should be set at about 1.6k to start with. And then lowered to increase the voltage. The vtt voltage raises itself when you uppen the vddr voltage. You should watch out with the mem vmods because they can give lots of artifacts. After reinstallation of the drivers i suddenly didnt have any artifacts anymore. Strange , so be careful. The mem vmods gave me about 5~10mhz more mem speed. Setting the vgpu voltage @2.4v gave me 30 more mhz on the core. I'm now running 380mhz core rock stable with watercooling. 400+ mhz should be easy with better cooling + more volts.
These mods should be done at your own risk.
