GPU overclock

#1JusDoPosted 10/13/2013 6:16:01 PM
For those who have or have had a Gigabyte GTX 770 windforce 2gb OC, have you ran into trouble while trying to overclock your card?

I know there is an issue where some people cannot raise the voltage past 1.2v where as i am in the same pool, but idk if thats the case. It may just be that my particular card cannot be OC'd.

When using afterburner i can raise the gpu clock to +30, but anything above +40 and my benchmark program either crashes or the screen goes black for 4 seconds and my gpu gets reset to default settings. I even used some games that have benchmark options and they do the same thing when i run those games on max.

~ Gigabyte z77x ud3h mobo
~ i5 3570k - Hyper 212 evo
~ 8GB Corsair vengeance
~ HX 750 watt psu
~ Windows 7 64bit

That GTX 770 already boosts to around 1200MHz at stock, so even a seemingly small overclock may be unstable. Have you tried the Afterburner voltage hack?

I dont believe so. Ive read someone altering a file and they were able to raise the voltage past 1.2 but i didnt read too much on it.

Well your GPU clearly isn't stable past +30MHz. Either attempt the voltage hack or you're stuck where you are.

Keep pushing it, I got mine to 1320mhz with 1.2 v though its a EVGA card and EVGA cards dominate the benchmark leaderboards.

try raising the power target to max
