Cannot overvolt my RoG striker 760

[Bartos775]

I bought this card quite a while ago and now I started to mess around with overclocking it. The momory was fine, I was able to pump 1GHz up, the GPU was another story though. There I could add only like 50MHz, anything above made the screen flicker black and or crash the driver (the driver did most of the times restart itself). But the biggest problem I have is that just cannot overvolt the card. I tried like every overclocking software on the plannet and none of them did anything with the voltage, temperateres never hit 70°C. So I dont see why it does not work. If somebody can tell me what  to do please tell me.

well some require custom bios to over volt. i know i had cocked my 7900 gs so it just wouldn't let me overclock anymore, would just refuse to take it.

You will have to find a hack BIOS for the card and flash it, but there is a huge catch.

If you flash it with a wrong BIOS the card will brick, and there will be NO WARRANTY. Jayztwocents made a vid of how to BIOS hack a 780 but there are no links, just the way it's done, i suggest you to watch it carefully. 

 DO NOT ATTEMPT WHAT HE DID! This vid is about a 780 BIOS hacking NOT a 760, but will give you a general idea of how it's done!

to add to your post, there was a linus video recently on the light modding of bios, to enable zero fan speed. idea is similar.

I did not mean any massive overvolt. If I push the voltage slider all the way to the right that is +12mV, my GPU monitor still shows 12V (not 12.012).

Is this just my card or does every Nvidia GPU not overvolt?
