Overclocking Performance

Using Furmark to measure stability we were able to attain a core clock of 957MHz with a memory clock of four.44GHz, just the system would crash every bit soon as we opened a game. We lowered the memory and GPU frequency past 10MHz and tried opening the game again to no avail -- the organization froze. After repeatedly reducing the frequencies, we eventually arrived at a core clock of just 830MHz with a memory clock of 4.2GHz, a far weep from the original overclock of 957MHz.

This mild overclock improved frame rates slightly, just it made very little difference overall. Given that the GF110 is the peak of the Fermi compages, the express overclocking didn't shock us.

Past increasing the core voltage to 1.25v with Asus' Smart Doctor software, we were able to reach 1000MHz. Unfortunately, this was extremely unstable and even at 960MHz nosotros ran into issues. While we were able to consummate a few tests, the results were not as expected.

Although there were no signs of throttling, the results were the same as those from the 830MHz overclock. Winding the frequency downward to 900MHz didn't amend anything either, and nosotros ultimately gave upwardly. Despite the eye-catching "Voltage Tweak for up to 50% Faster" sticker on the box, we couldn't accomplish annihilation close to that effigy.

Information technology should too be mentioned that the Asus ENGTX580 card comes "factory overclocked," but the meager 772MHz to 782MHz heave (that'due south 10MHz) should take given us an early on hint of things to come.
