Gigabyte OC Guru II is a small overclocking tool for Gigabyte's dedicated GPUs based on NVIDIA and ATI/AMD chipsets. The program also handles very well with support for graphics cards from other manufacturers installed in laptops and desktops. After starting the program works in the system tray, where it is available in the form of a small icon.

The Gigabyte OC Guru II main window brings together all of the most important functions to monitor basic GPU parameters, modify graphics and embedded memory frequency settings, and manipulate voltage, fan speed and mode. They allow you to overclock the GPU in order to achieve the highest possible performance, e.g. in demanding 3D games.

Importantly, the tool allows you to create profiles containing many different configurations. According to the manufacturer's assurances, the current release of the program supports NVIDIA GeForce 200 series and later, as well as ATI/AMD Radeon HD 5000 and later.
