GPU Tweak

With the launch of the MATRIX GTX 580, ASUS has also released a new GPU overclocking tool.

GPU Tweak is a nifty utility which combines several function. It allows setting of clockspeeds and voltages as well as monitoring functions. On the GTX 580, the core voltage, PEX_VDD and memory voltage can be changed. GPU Tweak also allows modification of video memory timings.

Interestingly, GPU Tweak allows separate control of both fans on the MATRIX GTX 580.

GPU Tweak is decent enough in terms of user-friendliness. It even works on other (non-ASUS) graphics cards, though voltage controls may not be available. Our only gripe is that some of the text is not skinned properly, making it difficult to read. An example of this is in the memory timings dialog, shown above.

Fortunately, ASUS has promised future updates and improvements to GPU Tweak, such as 720p video recording. A live update function lets you check for the latest version.
