ASUS HD5850 Reference for comparison
Our overclocking tests used a combination between the ASUS Smart Doctor, that allows us to modify the speed of the core and also the voltages, along with Furmark to test the stability of our overclock.
Starting at the default 765MHz we quickly hit 940MHz before any voltage adjustment was needed. It took an increase of 0.1v to move to 980MHz with stability and eventually 1.27v to crack the 1GHz barrier. Even with our fan at a modest 50%, the same we use with all our GPU overclocks, the HD5850 TOP didn't pass 65 degrees C after 5 minutes of the intense Furmark benchmark.
Temperatures were taking from GPUz after 5 minutes of Furmark testing. Because of the auto-underclock when in 2D applications the idle temperatures were within a gnats chuff of each other and so have been left out for clarity.
So we know what we're using, and what it'll do. Let's see how it performs under pressure.
