Overclocking For Fun and Profit

Overclocking Results:

GPU (Core) Speed: 650 MHz 682 MHz
Memory Speed: 1.55 GHz 1.6 GHz
If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

Overclocking the Asus EAX1900XTX 2DHTV/512M/A was not very difficult, but it was difficult finding a program that would allow the right clock speed adjustments that was hard.

RivaTuner didn't work, neither did ATi Tool or PowerStrip. Finally after playing with Rage3D Tweak did I find our saviour, unfortunately the overclocking options with Rage3D Tweak were a bit limited.

Starting with the 'R580' core first, the clock speed was slowly increased in 3-5 MHz intervals. The VPU core speed was passed the 675 MHz mark but didn't go much higher than that. It topped out at 682 MHz. Anything higher and the Asus EAX1900XTX videocard would throw a fit and lock up during 3D benchmarks.

Core temperatures exceeded the 70 degree Celsius mark, perhaps if there were better cooling on the 'R580' VPU, it might be able to clock higher.

Next up was the 512MB of Samsung GDDR3 memory which has a default DDR clock speed of 1550 MHz (ie. 775MHz). Going forward in 5 MHz intervals, the Samsung GDDR3 memory easily hit 800 MHz (or 1600 MHz DDR), which is smoking fast. Unfortunately that is as high as the Rage3D Tweaker would allow us to go.

In the future when more enthusiast friendly overclocking utilities are available, we'll revisit overclocking the Asus EAX1900XTX/2DHTV/512M/A videocard and see if we can't push it a little further into the stratosphere.

The ATI 'R580' core and Samsung GDDR3 memory had absolutely no issues running together at each components respective maximum speed. Then again, ATi videocards never really suffer that issue like nVIDIA videocards do. Users who are willing to be a bit more extreme will definitely benefit from 3rd party VGA cooling systems, like the Zalman VF900 for example, the Asus EAX1900XTX is certainly one hot videocard when its overclocked!
