EVGA GTX 570 Superclocked tested - 7. Overclocking, Thermals

Review: Reference design, higher clocks


Overclocking

As its name suggests, EVGA GTX 570 Super Clocked is a factory overclocked graphics card. Its GPU runs at 797MHz and the memory at 975MHz. Just to remind you, Nvidia’s reference clocks for this card are 732MHz for the GPU and 950MHz for the memory.

A 65MHz GPU overclock is a respectable one and will surely bring about visible performance increase. However, any additional overclocking on our card was limited by the core’s voltage.

MSI Afterburner 2.1.0 Beta 5 reports that the card’s default voltage is 988mV, which limited us to 810MHz for the GPU.

We pushed the core voltage to 1088mV and achieved stable 870MHz, which was the maximum we managed. Note that Afterburner 2.1.0 Beta 5’s maximum voltage is 1100mV, but further voltage increases didn’t do much to improve our overclocking results. We managed to push the memory to 1110MHz (4440MHz effectively).

Thermals and Noise

As far as noise levels go, the GTX 570 SC’s cooler is almost inaudible when idle, with GPU temperature around 45°C. While the GTX 570 SC isn’t too loud during operation, it was the loudest piece of equipment in our rig. In our case, intensive 3D resulted in GPU temperature of about 86°C.

Good review but why put the 6950/6970 in the 2nd and 3rd spot on the graph when they should be 5th and 6th?

Quoting MATTEEDO:

Agreed! It should look a little more like this

Minus the inaccurate grid, but I can't complain about a free kids website that lets you make a quick free draft.

Edit: I used the one from AVP @ 1920x1080. It's been a peeve of mine about most of the reviews here. And Mine could be changed depending on where you place importance, w/AA or without. Oh and I mixed up the order of performance, on the 6970/570 SC. It was done in a hurry so sue me if its a big deal.
