Turn your GTX 680 in to a stock GTX 770 - Page 33

post #321 of 391
So, I have an EVGA GTX 680 4GB, can I take a Zotac GTX 770 4GB bios and flash my card? Or does it not work that way?

That should work but always remember to back up your original bios in case it doesn't or something goes wrong.

What are the clocks on the Zotac? Watch out for the memory OC. 7 GHz can be way too much for some GTX 680s especially the 4 GB ones since they have higher density memory and generally it clock lower than the 2 GB variant. So if you are not careful you might end up bricking the card if the memory is not stable at 7 GHz..

Most 680's I seen are able to push 7.2ghz on the memory with stock volts I myself am getting 7.6 ghz memory and 1346mhz core and I have tried the 770 bios thing and found it to be a waste of time but also seen others that have got a performance boost, but I think it just might have been placebo effect

Golden card. and probably 2 GB. 7.6 GHz memory is way above what most 680s can do. Still it won't hurt if he/ she tested the card @ 7 GHz before flashing. It doesn't worth it to find out that it is not stable when it is too late right?
Nvidia clocked the 680s memory @ 6 GHz for a reason, the 770 is equipped with a better memory and comes @ 7 GHz at stock.

true, I did not think of that but only because I figured he would have tested it already. I should remember that not everyone would think of that so thank you for bringing it up

Plus I have a classified card so I have the advantage of multiple bioses

EDIT>>>>> Oh and no my card is 4gb as it is the classy as I just said. But I have done allot of searching on OC'ing them and seen allot of results of coarse and it seems that most are able to hit 7.2 even the 4gb cards. The 770 and 680 are just about the same card and the fact of the better ram is still on the boards if that is true or not , depending on the card of course, I mean if you got a crappy bin on the core and ram then you are not getting near 770 stats

Second Edit>>>> If you want a copy of my bios I am going to include it, it is a EVGA Classified card so the fan is allot better than most stock cards and from what I have read better power phases, and I have pushed mine to 400 watts with the TDP 1320mhz and Ram at 7012mhz with no boost] clocking but I could change things around if you needed me to

Thanks for the responses guys. Currently, I am at 1300mhz for the Core, and 7400mhz for the memory on 1.21v.

I was looking at flashing to see if the volts would unlock to 1.3v. Would that work?

oh, no there is a soft mod that works for afterburner and they have everything you need to do to get it working on the page (instructions) it is here on OCN if you search "Soft Mod AfterBurner" you should find it. I think that is the only way to get your card to 1.3v, I use the classified tool which is like the EVBOT for mine but I don't think it works on non classy's


EDIT>>>> Good luck OC'ing seems like you got a good card if you are at 7400mhz vram 1300@1.21volts 100% stable

I think I found the right thread, is this the one you are referring too?

There is a huge benefit from flashing 680 to 770. 680 throttles GPU at 70c and uses Boost 1.0, which is power-based. So your GPU OC clocks often fluctuate, go up and down, creating uneven FPS in games and even mini stutters. 770 uses Boost 2.0 that is temperature-based and you can select up to 95C as the max temp at which GPU OC will throttle and clocks will go down. FPS in games with 770 is more even, with way fewer clock ups and downs, creating smoother gaming experience. Its high temperature limit is safe and keeps fan from spinning too fast and making noise.

Memory is of no issue. If your memory OC is low, then edit the BIOS with your max memory OC. Do not touch the rest.

I recommend using reference nVidia 770 BIOS before trying brand BIOS.
