NVIDIA GTX 680 BIOS Flashed to GTX 770

680 flash

Apparently you can flash your GTX 680 to a GTX 770. Yes, it looks like the GTX 770 is basically a reiteration of the GTX 680. The BIOs will change your default clocks from 1006/1058 MHz to 1059/1125 MHz and the memory will also be overclocked from 6008MHz to 7GHz. According, to the individuals that have tried this BIOS you will will get a 5-7% boost in FPS. Furthermore, one user from Reddit ways in on the modification and what exaclty is in store for us with the new GPU.

The upcoming GTX 770 is a GTX 680 in disguise. NVIDIA has gently revised the GK104 architecture, mostly with process improvements, but the 770 is basically the same beast! Which is good for us enthusiasts. 🙂

By flashing the included BIOS (.bin) to your board, then dropping the included .inf file into the 320.00 driver package before installation… you too can have a GTX 770 weeks before it’s released! Please note it has to be a 320.xx driver, as support for the 700 Series was added in the DLLs around this time.


Again, if you have a GTX 680 be careful if you decide to give this a try as you are modifiing the BIOS of the card and generating a tad more heat with the OC, so do this at your own risk. It’s also unclear what else this BIOS has changed as the voltage of the card may also be increased, which would also affect heat and power of the card. So, there you have it, the GTX 770 is basically out in the open, but as always more details are expected to be revealed on the card once it is officially announced sometime in late May or June.


Techpowerup has weighed in on the issue and they have stated that this BIOs modification may be a bit of a hoax. While you are quite capable of actually applying this to your card, it seems that this BIOS mod may have been created by a third party. This means that this may be a basic BIOS mod that just OCs your card and makes it appear as a 770. They also suggest that some individuals do this to try and reband other cards and pass them off as different products.

We tested the BIOS with some of our own GTX 680 cards, and found it to be nothing more than a modified GTX 680 BIOS (for increased clocks) with a modified driver INF file that makes the GeForce driver display a different model name. The BIOS just has made-up clock speeds that could run on some GTX 680 cards, but could be unstable on most.

…Third-rate companies often get away selling rebranded fake graphics cards in developing markets using this method. For example, they buy cheap GeForce 210 cards and sell them as GT 630 for twice the money.

Unfortunately, it is still unclear what exactly is going on with these BIOs, despite these claims by Techpowerup. So, the BIOS isn’t necessarily 100% disproven since the real deal could be something similiar. We will have to see what happened when the 770 is officially announced to see how this matches up, but in the end it might be easier and safer to just OC your existing 680 instead.
