8800GTS Stock GPUvcore is 1.27v @704mhz on air

[gOtVoltage]

I want to up my Vcore on GPU only ! My memory gets 2300mhz with no Voltmod! My GPU is stock Vcore @ 704 @1.27v , Shader is 1782 and my Memory is @ 2308mhz@2.08v STOCK. I dont want to mess with the ram ,The ram is running too good as is! Being on Air this is amazing i think with a A3 320mb GTS that is over 1year old. So I only want to do a Vcore mod...

1st Can the GPU Vcore be changed thru the Bios and is the pencil mod really not possiable?

2nd What can a 8800GTS320 do on Vcore? Mine is @ 1.27v and ive read that the 640mb's can go up to 1.4v..on the GPU! Id be happy with 1.3v or 1.35v

3rd where would i go to get the correct VR to solder the mod with ,,IE :Radioshack?

A screenie of my clocks on AIR with moddified stock heatsink. GPU-Z reads my shader wrong ive already tested this By running my shader @ 1674 and losing 250+ points in 3Dmark06...If i try to raise it to 1836mhz which is the next step higher i dont have enuff Volts! Dosnt matter if i lower my memory either
