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.
