Graphics Card Overclocking


Thanks to motherboard and VGA manufactures, overclocking has become such an effortless task, giving literally anyone the chance to overclock their components with very little risk.


When it comes to overclocking graphics card we use and recommend two program - for ATI cards you can't go past ATI Tool and if you're on the other side of the fence and using an nVidia card the Coolbits 2 registry hack is it. Both programs offer an Auto Overclock feature which is what we use.


The PowerColor X800GT EVO was increased from 500MHz on the core to 557MHz and 552MHz on the memory to 595MHz (1190MHz DDR).



3DMark05 always sees a noticeable performance gain when overclocking the graphics card. While it isn't huge, it works out to be roughly a 5% increase.



Doom 3 again sees a good noticeable performance jump in numbers but at stock the X800GT EVO offers a very playable frame rate at these settings.



With Far Cry being so CPU limited by pushing the graphics card further we see no difference in performance. It is only when we overclock the processor we see an increase in Far Cry performance.
