Anyone on here had a go, my 680 has hit its limit at 1270 core, 1820(~7.3Ghz) mem and see that some of the expensive cards have higher voltages to the core and memory delivered by special BIOS, as my card barely cracks 35-40C when gaming I reckon I could handle a bit more voltage. Any one got links or pointers to a guide about on how its done or if it is even possible on a reference card? Mine delivers all its got at 1.175v.
Afraid I'm still on G80. However, I know there's a guy called Kit over on XS is involved a lot in that sort of thing, worth having a check in their NV subforum to see if you can glean any knowledge.
Search around for vbios works with nvflash it's what I used on my 580s a while back No clue if either is kept up to date. Word of warning you could brick the card pretty easily if it goes wrong and for the sake of 50mhz I dout id bother. It's one of the reasons hard core overclockers prefer modifying the card less risk.
