ASUS MATRIX GTX580 P/2DIS/1536MD5

Overclocking hardware tools, TweakIt and ProbeIt are directly embedded onto the graphics card firmware, while a Safe Mode button offers an easy reset option worry-free hardware overclocking. All new GPU Tweak provides professional graphics overclocking for PC enthusiasts. 19-phase Super Alloy Power technology provides more headroom for overclocking with a 15% performance boost, reduced running temperatures and prolonged product lifespan. Award-winning DirectCU II thermal technology with sound-dampened dual fans provides 600% greater airflow and 20% cooler performance than the reference design.

TweakIt provides users with flexible overclocking control even when running benchmark programs! The “+” and “-” button puts overvolting adjustments in the user´s fingertips, offering them performance optimization options during game play to gain the competitive edge. ProbeIt takes the guesswork out of locating the graphics card´s measurement points, identifying them clearly in the form of 6 sets of detection points so you´ll know exactly where to get quick yet accurate readings using a multimeter.

Cooling is well taken care of by exclusive DirectCU II technology that puts copper heat pipes in direct contact with the GPU. The pipes efficiently transfer heat through two massive fans that deliver 600% more airflow than the reference design, resulting in a 20% lower operating temperatures. And a multicolored LED MATRIX indicator at the rear of the ROG MATRIX GTX 580 gives an instant and easy-to-understand visual display of the current GPU load.
