equivalent to EVGA's "precision" except works on Radeon 5800's Overvolt and overclock!

hmm tried it but the performance went down as I increased the voltage and core speed, don't know whats going on, I don't even think it is overclocking my card though the OSD says the clock speed to be right when I bench. but seems like ati drivers are controlling the overvolting for some reason.

Overclocking the new generation of cards is so differcult, because ATi implented error correction machinism.
What this means is that even when there is error in the card from OCing, it won't show artifacts (yellow dots etc), only thing you see it performance goes down.

Edit: W1z explains it pretty well in his review.

I thought that was only related to memory, my memory has been tested fine at 1250, and I really don't feel the need to go any higher. error correction is only memory overclocking related, I don't believe it has anything to do with gpu.
