Hey all,
Attention to all you GTX 780 owners, what kind of overclocks are you able to hit? Voltages? Feel free to put what model you have too! Just out of curiosity since I have one myself, and that it is one of the best cards out atm.
Also, what kind of setup are you guys backed up with? PSU? CPU? Memory?
I currently use the Asus GTX 780 OC. As of right now I have no need to overclock as I am getting great FPS numbers and feel no need. I would like to hear what kind of numbers others are getting on their 780's though.
1080p guy, lol. push it, push it good.:)~
i have evga's sc acx flavor of the 780
the factory overclock is set at:
base clock: 967 MHz
boost clock: 1020 Mhz
on top of that I have been able to achieve +60 to the core and +130 to the memory clock in precision x without overvolting. (So 1027Mhz base clock, 1080mhz boost, 6268mhz effective mem clock)
My system:
850w psu, Intel 4770k OC 4.4ghz, 8 gb 1866mhz ram
Benq XL2420T 120hz monitor
I am pretty sure this is stable. I ran Heaven for one full benchmark without crashing and played about 4 hours of rising storm and natural selection 2.
As far as benchmarking I got 4939 points in 3DMark firestrike.
I also tested Thief's in-game benchmark and obtained:
min: 53.1fps
max: 119.4fps
avg: 82.5fps
For comparison, at stock clock (+0 core, +0 mem, 967mhz for me) i was getting
3DMark: 4735
Thief:
min: 49.0fps,
max: 114.8fps,
avg: 78.9fps,
I havent yet had the time to really test out any higher overclocks, but I know for sure Heaven crashes around +85mhz to the core and +230mhz to the memory.
I am not sure if I should overvolt or not. Currently I am getting no hotter than ~60 C, but have temp target on Precision X set to 95 C. Are temps the only thing to worry about? Or will overvolting damage some other part of graphics cards?
How are these results compared to that of your (i am assuming reference) 780?
Solid enough scores but it can be more impressive with overvolting; something you probably will notice. I did indeed overvolt in order to obtain around a 1280mhz max boost along with 6800 mhz memory. It's usually pretty safe if you find a decent number, I mean in theory adding voltage will reduce the lifespan of your video card, but nothing really significant anyway.
Basically, I was able to get around 1.2V or 1.22v in order to achieve this. Btw, i stuck with a slightly lower memory speed in order to reduce heat because it wasn't affecting too much after that anyway. I believe i was able to get to 7200 though without it crashing. All cards will work differently of course, but this is what worked on my stock. You can get pretty sweet performance boosts for a bit of tweaking ;)
i have a Asus gtx 780 OC
i got mine running at 1188 boost clock
i tried overvolting, but i couldnt get it any higher even then.
did not oc the mem clock yet. is there even any benefit from OC'ing the memclock?
cool, yea i may get around to trying out overvolting on my card once i get a chance. It handles all my games just fine for now, even on a 120hz monitor.
I am more excited about testing out the new 337.50 drivers from nvidia. Got them downloaded just last night. Wanna see if i can even get anything close to what nvidia is boasting.
Let me know if you see any improvements for yourself and on what games.
generally yes, but less so than directly OCing the core clock i think.
depending on the game you are running, and how much high textures and filters it has, it will use more gpu memory. So its probably on those games you will see the most benefit of OCing the memclock

Yeah usually in higher resolution gaming you can take advantage of memory overclocking, nothing really like OC'ing the cores but it could help keep it smooth. And yeah, HowDoiForum messing with those voltages are a cool thing because it can honestly push your card enough to make it butter smooth in some cases, or really put monitors with higher refresh rates to use since they can collaborate better with your card if it happens to be pushing some high frames. Like if you're getting like 80 frames avg. on a game with 120hz monitor that's gonna look mint.
