Question About Temps on GTX 560 Ti Classified 448-Core

post #1 of 19
Thread Starter 
Hey guys,

So right now I'm sitting with a GTX 560 Ti Classified 448-Core that I've had for about a year and a few months. I used to run it at stock settings (797/1594/1950 @ 1.013V), but I decided to overclock it about 3-4 months ago. After toying around with overclocks, I found that 880/1760/2150 @ 1.025V was stable and beneficial enough to keep.

Obviously when you overclock and concurrently increase voltage, temps will be higher. My temps are at 34-35 idle and anywhere from 45-55 in-game (CoD4, Black Ops II, PlanetSide 2, BF3).

My buddy, who has a GTX 580 Twin Frozr, says he idles at 50.

Are these temps okay to play at? Am I not pushing my card to its max? I also have my fan curve set to this.

I'd love to get some input, so let me know what you all think.

Voltage, overclock and temperature are all very good. Keep load temps below 80'C is the set rule for gpus.

Would going up to 900/1800/2200 be better? Just trying to get the most out of this card without breaking it.

If the temps are good, 1.1v is no problem for that beefy card. What can 1.1v get you? That's where I'd leave the overclock at.

Are you sure that 1.1V is safe? I'm only at 1.025V, haha!

I will second that 1.1v is reasonably safe voltage to run your card at, and honestly I only say "reasonably safe" instead of "perfectly safe" because anything can happen and there is always some risk to overvolting.

1.1v is safe for that card, doesn't mean you need to go that high. Seems like you have a great overclocker on your hands. Maybe just go 1.05v instead so the card is still quiet and cool. I run 1.113v on my Asus DCii 570 for 900Mhz core to give you an example.

Thank you for chiming in! It's good to get a second opinion, not that MrTOOSHORT's was good to begin with, but you know what I mean. I agree.

I will start moving up slowly, but my fan already gets pretty loud with my current fan curve setup. What do you think is a good max idle temp to hit? It's also probably good to mention that I'm on stock cooling (although EVGA's stock cooling on my model is actually very good).

Don't worry about idle temps too much, load is where you look. Like I said, under 80'C load and you'll be set.

Idle temp is almost meaningless, try to stay away from the 80s on your load temp and that will be great. FYI your chip is specified up to 97C by Nvidia, I personally want to stay 10C from the Nvidia limit at all times no matter what, and then I like to have another 5C for comfort and wiggle room if the case gets dusty or the house gets hot etc. So if I was personally OCing your card I would stop raising voltage when I hit 80-82C load temps and then see what the max core clock that voltage will get you.
