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 Galaxy 512MB 7800GTX was increased from 550MHz on the core to 576MHz and the memory was increased from the standard 1.7GHz to 1.74GHz. Unfortunately not a huge overclock but we are seeing this on most 7800GTX 512MB cards at the moment.
The small overclock gives us a small increase in 3DMark03.
Doom 3 doesn't get any advantages with the overclock with the scores being almost identical in both tests.
Far Cry being so CPU limited doesn't see anything when we overclock the card unlike our CPU overclock tests we saw on the previous page.
