GIGABYTE GTX 680 OC WindForce 3X 2GB Review

Software (Gigabyte's OC Guru tool)

Although similar in functionality to other brand's overclocking utilities, we don't agree on the wasteful (touch screen-ish) layout or lack of manual keyboard input (mouse only) for the adjustable values. The TDP/board power limit on this 5-phase board is restricted to a meagre 111% (which brings it to 250W from 225W programmed in the VGA BIOS), marginally higher than 4-phase reference designs. Core voltage, which is currently done through a driver interface rather than hardware control, cannot be adjusted by software means either.


Automated VGA Bios and driver update facilities are also available.


Thermals / Overclocking


Methodology: We set the fans to 100% (strangely the sliders will only let us apply 85%) and looped Unigine Heaven 3.0 on extreme settings for 10 minutes and took the maximum temperature from the ondie sensor. Ambient temperature was 18 degrees.

To prevent GPU Boost (NVIDIA's adaptive throttling mechanism to cheat in benchmarks) from interfering with the clocks, we need to change this setting in the Nvidia Control Panel.


Default settings: 57 degree celsius


Overclocked (1288/1552MHz): 60 degree celsius
