Thanks for the quick reply. So in short - please correct what is incorrect if you don't mind:

I can volt up to 1.212v without any modifications using Afterburner/Precision X, however, anything over that can be done the mods/custom bios? No hardware/physical voltage mods required?

I ended up going with the EVGA GeForce GTX 770 Dual SC w/ EVGA ACX Cooler (P/N: 02G-P4-2776-KR).

yes unless the card does not like the bios mod(which would be wierd because most cards do.

So it looks like with stock bios my card can only volt up to 1.2 and no further.

In the OP there is no Dual SC bios for the 2048 version but there is for the 4GB version. Additionally, there is a SC version, however, not sure that this works with the Dual BIOS card?

Thoughts?

Here it is - do you use NiBiTor to edit or something else?

Also for everyone else - when I was playing around with the card and bumping up the frequency today on the GPU I would get a black screen than an OpenGL lost connection error 7 when running Kombustor.

I am wondering if this is a voltage issue with the card or perhaps I need a better PSU.

ASIC score FWIW is 74.5% - I have read this isn't necessarily a bad thing as it will clock higher than a higher scoring ASIC card, however, it will also require more voltage than higher scoring ASIC card too.

you may need more voltage and if so this mod will help. if the psu can provide it that is. I set the voltage to 1.187 but i made 1.212 available because if that issue is the psu or the bad card a computer restart can easily set it back to 1.187 since touse 1.212 you will have to raise the voltage in a oc software. joder_GTX-770-2048-SC-DUAL_GK104.zip 251k .zip file

Hello everyone! Question... I have 2 Gigabyte Windforce III GTX 770 4GB OC'ed Edition cards on sli. Can I actually overclock them more than what afterburner, guru and EVGA Precision apps allow me to? Can I unlock the voltage and get more performance out of them? If so, would it be drastically more powerful to influence me to do so? What kind of benifit would you say I'd get out of doing it? Thank for the reply guys. This is a little knowledge for me to educate myself, at this point all my games run perfectly running on Ultra Spec @ 1080 and so fourth... But in the future I think we can expect to see more demanding games, so It'd be good to know. Thanks! thumb.gif

yes you definitely can gain more performance though it won't be the same as running one card and doing it which will gain a lot. I don't recommend it as its not worth it since you are in sli and by the time the 770's are not sufficient anymore maxwell will be out and probably other cards.

After almost a year of following this thread as a guest, I've joined the club at last!biggrin.gif. I have to give it to you guys this is the most mature and most helpful forum I've come across(and I'm on a lot of them).

I've been trying to eek the most out of my 770 with tips from you guys, but now I'm hitting the limit it seems. The maximum stable I get on my ACX 770 on is +80 on core and +200 on memory with voltage of 1.212V. This gives me a max boost clock of 1280Mhz, stable for my other games but causes regular TDRs on Far Cry 3 fully maxed with 4x MSAA. The TDRs show up after about 20-30 minutes, sometimes longer. However I get much smoother and consistent fps with this OC in FC3, it's a joy to play. Bumping it down to +78 on core reduces boost to 1267Mhz which doesn't crash Far Cry 3, but gameplay is noticeably choppy especially in areas with lots of trees. I use an aggressive fan profile in Precision X so temps stay below 72°C at all times so I don't have temp issues(I live in a tropical country).

I'd like to know if I can get a higher overclock stable for the demanding games especially since the reason I bled almost $2000 for the rig was for the upcoming GTA V(add Far Cry 4 and Arham Knight to that list) I can't afford to have my rig grow old on me even before I get that game. I read about the afterburner mod and bios tweaking in this forum, what would you guys suggest? My limitations are I can't RMA my card from my and current location(costs will be prohibitive) also watercooling isn't in my budget right now. I just wish I could make 1280Mhz or even 1291Mhz completely stable with temps under control, that would be enough for me right now.
