Gainward 680 4gb GK104 Unlocked.zip 56k .zip file

Hello, I have been following this thread and just now decided to join the forum in order to share this bios.

I have modded the bios for the Gainward Phantom 680 4GB to run at the factory OC of the 2GB version, and then some, and unlocked it to boost to 150% power limit. I have it running on 4 of these cards so far, so I know it is working pretty well. Baseclock is 1110.5 Mhz, Boostclock is 1150 and max boost is 1280mhz. Max voltage is 1.165V, and max power limit is 150%.

Well, we already know that the GeForce 770 will be a GK104 part, with higher clock frequencies. If it will have a revision of the gpu or not, or added features remains unknown. However, flashing your bios to run higher clocks most certainly will bring a 680 to 770 speeds or beyond due to the fact that it will be using the same gpu core.

This will not make it a "true 770" though. Thats why the the ini file is used to change it. The hardware ID of your card will still be that of a 680. So it is pretty pointless. it is just an overclocking of 680 and a trick to make it look like you have a 770 installed.

It does nothing more than what you do now with OC values. the ini just changes name displayed .

Very simple.

Then follow this:
Anyway to see voltage on the GPU?
I get lower fps now than I did on stock bios, 2fps lower in metro benchmark. And thats with a 100mhz increase on the core, 1097 (old) vs 1202 (new)
It sounds like it is power throttling . using AB or Precession look to see when the clock speed is dropping .
Is the power % at 100% ? or what is power value when happens

Do you have power slider limit raised and how much did you raise power management , if you did in bios mode .

Alright I've successfully flashed the modded BIOS provided by YounGMessiah (thanks again!) to both GPUs. I didn't think it was that easy to be honest. Was expecting it to be a lot more complicated.

Anyways, before the BIOS mod I could do 1215 MHz boosted clock. (1.175v I believe..)
After the BIOS mod I tried 1280 / 1267 / 1254 MHz boosted clock and all of them crashed.
Man I'm so disappointed. I haven't tried 1241 MHz boosted clock cause I have to sleep now I have a long day ahead tomorrow. But even if 1241 MHz is stable that's only a mere 26 MHz overclock with a 0.4v increase.

I'm guessing I got extremely unlucky in the GPU draw.

I'll comment tomorrow or the day after to update my stable overclock results. Thanks to everyone who helped!

its not 0.4v, it is 0.040 (40mv ).

to put that into more light, say you have a 3570/3770 , stock voltage was 1.050v and you OC it to 4.5 which needed 1.250v .
You increased it by0.200v (200mv) . not that that can be direct comparison of what is a lot or little voltage as many factors come into play but should give better idea of amount being added .
So your not really adding to much voltage but that is limit for reference card .

Do you have power slider limit raised and how much did you raise power management , if you did in bios mode .

The KGB automaticly raises the Powerlimit to 150% and voltage to 1.875 something and boost to 121 something.

I raised powertarget to 120% in afterburner, and then it stays at 1150-1202, but even then the fps is lower than with 1097 lol.
