[VC] NVIDIA GeForce GTX 680 Modified Into GeForce GTX 770

post #1 of 164
Thread Starter 

Quote:
Apparently the GeForce GTX 680 can be modified into GTX 770 with a simple BIOS replacement.

All you need to do is flash a new .bin file to your ROM, then replace .inf driver file and you’re done. Despite the fact that the GTX 770 will actually use a newer iteration of the GK104 processor (.425), technically this will still be the same GPU.

It is unknown at this time, whether the new BIOS increases the voltage of the processor or memory.

The new BIOS changes the default clocks to 1059/1125 MHz for base and boost respectively. Notice, that the memory was also overclocked to 7GHz point. Therefore I wouldn’t recommend to try it, unless you have a Dual-BIOS feature.

Very nice nvidia. I'll wager a guess and say the memory Voltage has been increased

The thing that interests me is if someone knows the 680 bios well enough to see if it says somewhere in there (after opening it in a hex editor that is) how much the max 3d volts on the 770 are. I'd guess NV has raised them.

Just because you can flash it, does not change anything. Woo it has a different name in GPUz but that is all you get. The card is locked down so you can not get anything like unlocked voltage from this.

I'm not going to believe it until I see it. ... I understand it to be possible, but until someone here shows me... I'm skeptical.
