I just got my new CPU Magazine they had an extensive article on Volt moding the 7900 GT with good pictures. I already purchased my Silver Oxide Conductive Pen after reading an article on VRZone. The Magazine made it look much easer so I did it. I tried to do the 1.4 V Mod but it didn?t work still 1.19V so I filled in another trace beside the first to do 1.5 I got 1.49. I can now get 666 Mhz GPU. Next I shaded the little silver spot indicated to raise memory Voltage with a #2 Pencil. It still says 2V but the Nvidia Driver Detect Optimal Frequency wants to run over 900 Mhz X2 For DDR=1800 Memory Speed. I'm very happy with the Mod I ordered a Zalman Heat Pipe W/Ram Sinks to keep it cool now its running at 75 C.
