Overclocking

There are no different 2D/3D voltages implemented in this card. It will always run at 575 MHz core and 700 MHz memory. You don't need to install any Sapphire software to run at their increased clocks.

Even though ATI's spec list states "Dynamic Voltage Control", there is no way to change the voltages via software. This means that if you need more juice you have to do a soldering voltmod.

We used ATITool to automatically find the maximum core and memory clocks (yes it works!) of our card.



In the end the card runs completely stable at 621 MHz Core (8 % overclock) and 806 MHz Memory (15 % overclock). Compared to ATI's default specifications this is an overclock of 24 % / 101 %.

For an already overclocked card this overclock is pretty amazing I must say. When I think of "pre-overclocked" I think of "card running at its maximum". Sapphire did a great job here, having some clock headroom means that the card will work stable even in hot cases or hot environments.
