Sapphire X1950 GT

Overclocking

Previous versions of ATITool did not work right on RV570 cards, that's why many reviewers complained about the impossible memory overclocking. Since ATITool 0.27 Beta 1 you can overclock all RV570 cards using the "Use Driver Level Overclocking" switch in settings.

We used ATITool to automatically find the maximum core and memory clocks of our card.



In the end the card runs completely stable at 608 MHz Core (22 % overclock) and 743 MHz Memory (24 % overclock).

This is a pretty nice overclock which brings the card much closer to the X1900 GT and the X1950 Pro. Our overclocked card pretty easily beats the X1900 GT, but the X1950 Pro is still out of reach because of its 512 MB GDDR3 advantage.
