The guys are mostly right about flashing the GTO to GTX bios, the memory timings are tighter for the GTO bios compared to GTX bios. However there are other kinds of modded bioses out there that will enable GTO's to be clocked slightly higher, refering to the GPU clocks.

But since your getting such good GPU and mem clock speeds, I dont recommend you mess around with something good.

I'm only able to hit GPU of 720Mhz and Mem of 1650, of course with no volt mod performed.

Your mem clocks rocks

I'm using an MSI 7900gto.... so whats your bench results so far with ur gto and proc?
