It's not really that hard. It is just like overclocking any other ATI card. Go to Omegadrivers.net, download that, and use ATI Tray Tools. Let it try and find the max for your memory first, then gpu, then make sure they are stable (you may have to do less than the max ATT found) and then click scan for artifacts. Then run 3DMark05 and tell us how you do!
