Overclocking Potential

Our sample of the EVGA GeForce GTX 580 Classified 3 GB didn't show much in our overclocking tests. We could only increase its GPU clock rate to 920/1840 MHz and its memory clock rate to 4840 MHz.

We had done better with a Gigabyte GeForce GTX 580 SuperOverclock which had been able to work at 935/1870/4860 MHz. As we’ve noted above, switching to the OC mode didn't affect the EVGA card's overclockability.

When overclocked, the card’s GPU temperature was 86°C at a fan speed of 3090 RPM.

That was hot and noisy, of course. Overall, we were left rather disappointed with EVGA's original cooler.

Winding up the descriptive section of this review, we can tell you that there are special software tools included with the card: EVGA Precision and EVGA OCScanner. The former allows controlling and monitoring the card's clock rates and fan speed. The latter resembles the well-known FurMark.

You can use it to get exhaustive information about the card, its frequencies and voltages and also stress-test its stability in overclocked mode.
