Safe overclock on GTX 580?

post #1 of 15
Thread Starter 
Well I seem to have a stable overclock of 950/4500 on my GTX 580 but I'm unsure about the voltage and temps.

Idling at 27-32C and loading (hour of BF:BC2) at 80C. Here is a screenie of my settings.



So are these settings safe for 24/7 use of should I tone them down a tad?

That seems perfectly fine to me for 24/7 use if you are just gaming and doing other normal tasks. If you were folding 24/7 non-stop I'd say that voltage is just a touch high, but for average gaming then that's perfectly acceptable. 1.15v is the actual voltage you're giving that card right? Like you haven't hit the hardware overvolting buttons on the actual card have you? If you're actually only giving the card 1.15v then that's perfectly acceptable.

I would've expected better temps though, my DCII 570 never got that high and was very very quiet and you've got the same cooler with only a little more heat to contend with.

Just using the voltage slider in GPU Tweak, no added voltage via hardware buttons. The fan is set to auto, which can't be heard when the card is at 80C, so I don't mind if those temps are still within the safe zone.

I'm confident in saying the reason for such high temps is because I have my H100 setup as an intake, which heats up the case quite a bit. I could have the fans set up as an exhaust but they'd be pulling as opposed to pushing. Surprisingly, the H100 doesn't fit in the 600T that well.

Side note: With the stock Intel HSF, the GPU temperature was around 67-70C under load with that overclock.

Isn't that H100 in the roof? If so you really want it set as exhaust, if it's set as intake in the roof the you have a whole lot of positive pressure and a whole lot of internally exhausted heat, that makes for really high case temps, much higher than they need to be. It'd certainly be worth the 3C your CPU would increase in heat to lower every other temp in your case by 8C (GPU, CPU VRMs, NB, etc.),

I'll try as pull-exhaust. I expect it to make a huge difference to the CPU temperature though. They can't be set as exhaust and push from within the case because the case is not tall enough.

As long as you don't get any errors on OCCT, you should be fine

Oh I see, that's unfortunate but still think that the trade off you make there will be worth it. Just remember that when you lower your case temp (which you will, drastically) it affects everything in your case, so you will have a positive result on like 5 different component and a negative on only one component.

You sure you can't fit the H100 as a push exhaust? It'd still be the same thickness of course because the order won't change the combined thickness but your there and I'm not so if it doesn't fit then it doesn't fit. That would reflect pretty badly on corsair though TBH.

The overclock seems stable. I'm worried about the temperature and voltage to achieve said overclock.

The design of the 600T allows two 120mm fans in the top compartment above the actual case. So, after flipped the fans around, I now have this:

Hot air exhausted out

Exhaust fans

Top of case

The voltage is 100% fine as long as you just use it a like a gamer, if you were using it like I do which is at 100% load 24/7 folding then it would be just a touch high (I personally would stick to 1.13v for 24/7 constant load). The temps are perfectly safe but there is room for improvement, that's why I'm recommending getting some more exhaust in your case because currently you have all of your hot components exhausting inside your case and you only have a single 120mm fan that you expect to exhaust like 400w of heat, not a pretty picture for your case temps.

Yeah, I got all that from your above posts . In my last post I was expressing my concerns in response to turtleslikejohn's comment.

With that said, I've flipped the fans around and I'm going to monitor the temperatures. I'll report back.

Thanks!
