i have an evga gtx 560ti 448 classified ultra and want to know if there is a driver that will increase the voltage to 1.163? default max is 1.150. was reading reviews on newegg for either a 448, 570, or 580 where someone claimed a driver update allowed a higher voltage. i always thought that involved a bios flash. btw, nibitor does not recognize my gpu bios, but when i submitted it, said it was already on file. i had 2 of these cards in sli and got a graphics score of 13300 in 3dmark11. im not sure but i think that is better than a 670. any thoughts?

✔ Best Answer
A driver could not possibly alter the voltage of hardware, but a firmware update might do it if EVGA have one for that model. Check their website:

I checked and they dont. i can get the card up to 970mhz on 1.150 without any overheating. i really need to go kepler.

I know this is an older post. Some guy was reviewing his card on Newegg and claimed a driver update allowed him to increase the max voltage. I knew it was BS when i read it. However a voltage bump to 1.163 might be enough to get the core to 1Ghz. The max from EVGA is 1.150. 2 of these cards in SLI will destroy a GTX 670, not sure about a 680.
