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 GeCube X1800XT was increased from 500MHz on the core to 577MHz and the memory remained the same at 1GHz due to our overclocking tool limitation.
GPU overclocking shows a very small performance increase when overclocking the graphics card.
Doom 3 sees a very minor increase with the overclock.
Thanks to Far Cry and its CPU limitation overclocking the graphics card gives us no performance increase.
