Convert your 7900GT into a 256Mb 7900GTX

t024484,
Do you still want/need that BIOS you asked about? I'd be happy to send it to your e-mail or I'll give you a linky to it over at mvktech as I uploaded it there the other day (Mavke didn't have it). By the way thank you for all the great work and info you give us all! Until I read a few of your last posts I had no idea what those little black components actually where up next to the D508, D511, and Q516 pads were. There responsible for the switching of 2D and 3D GPU voltages, and there called dual schottky diodes, very interesting! Keep it up man, many of us really apprecaite it!

Thanks you for your offer, but I aready helped myself by visiting MVKTech.
That's how I found out that you can change any 7900GT Bios by means of the Nibitor Voltage Editor, to have two VID levels.
Silly enough, if you could find how to enable the third and the fourth VID level, you could have your EVGA_SS Bios changed to have 1.55Volt instead of the current 1.45 Volt.
All the hardware, read all the little black fellows, are there to do the switching, all you need is the signal from the GPU to get it switched to 1.55 Volt.
