Some levels use more power than others, in the most hardcoe if you level around 98% that should be fine, if you flatline at 99% that's too much you're gonna have to OC the GPU, never mind about the VRAM speed as C2 don't bother too much about that.
MP uses less power than SP, i've had to up my volts again cause after 5 mins of MP the frames started falling faST, the 580 is an overclockers card it can be set safely at 1.15 volts(the asus goes up to 1.2), ...
Still being in the middle of summer take off the side of the case and setup a desk fan, i got 12" one, it's fine and keeps the whole rig as cool as possible on air.
With the gtx and its extra capacitors for OCing once it hits 900MHz on the core it becomes a different card, this was confirmed on the net, ...thing is once it hits 80C it's time to either down the volts or down the core speed, volts is imoprtant, if your playing MP or even SP for a length of time your gonna need extra. Here's a pic with the ideal ultra OC on the 580, it probably could run at 900MHz on 1.1 but not for a length of time.

Meh id like to OC my gtx 560 ti to 1GHZ but im scared of uping the volts...

"the 580 is an overclockers card"
I thought it's a "explode from heat as soon as you play a game" card

It does suffer from the same cheap VRMs the 590 does. But because its a single card and not a dual one it doesnt get as hot. But i would imaging upping the volts to high on the 580 will make it explode just like the 590.

The 580 has extra capacitors to handle the OC, the ASUS edition is called 'Voltage Tweak'.


^^That is one i have, .

Voltage tweak is just what they call the voltage adjuster in the ASUS smart doctor software. If you want some really NASTY oc you have to use smart doctor. when i had my asus 5870 i was able to hit 2v. Not that i would have dont it, but it does allow WAY more headroom than afterburner does. But again i would still be cautious with the 580. It may have extra caps but that does not negate the fact that the VRMs are still cheap.

so beautiful *tear*

Thanks man.
First two music overlays were copyright, this one is in places too, i like it anyways, gonna watch in 1080 see how it transfered.

I have the MSi GTX580 OC edition with stock cooler. The core runs at 823 MHz, and after half an hour or so of playing, it gets to around 89~90 degrees celsius. So 80C is actually pretty cool.

The game freezes if it stays at 91C+ for more than 3 hours or so(speculated, never really checked). I remember both crysis 1 and 2 stopped responding after i played both for 3 hours in a very warm day (~30C).

Oh yeah, voltage is at 1050 mV.

Im sorry but I have to correct you on "if you flatline at 99% that's too much you're gonna have to OC ". That is not even close to true. At best it means that your CPU is not a bottleneck to your GPU. If all the optimisations are good a system will allways try to render as many frames as it can.
