MSI GTX 770 Gaming 4gb OC edition?

post #1 of 4
Thread Starter 
Can the voltage on MSI afterburner be unlocked on this card at all? MSI GTX 770 Gaming 4gb OC edition? Been working with OC setting and I checked the unlock voltage box but it didn't seem to do anything. also what would be the best program for testing stable GPU OC?

I have been encountering the same issue. I have two of these cards running in sli and have been trying to work out the best overclock, but I cannot unlock voltage either. Also, there is not an option for shader clock adjustment either for me. I think this has to do with the fact that these cards are factory overclocked and we don't get the option to change the settings too much. Although I would really like to know how biggrin.gif

You may have to update your BIOS. The GTX770 is based on the GPU of the GTX680. Try searching or asking in this thread:

I think that the gaming edition gtx 770's from msi use the NCP4206 voltage controller. If it does you can do a softmod to change the voltage up to 1.3v and eliminate vdroop also. Here is a link to a thread that has all the information you need for doing this.

For air cooling that 1.3v would be as far as I would go with it, although with the application the zawarudo made you can push as high as 1.6v I think. Hope this helps thumb.gif
