Introduction

Overclocking is more popular than ever. And since it’s so easy to boost the frequency of your Intel processor, it would be a shame not to. But CPUs aren’t the only components that can be overclocked. The GPUs on graphics cards can also be speeded up, and so can their memory. And since an affordable card only differs from more expensive ones in its clock speed, overclocking can be your key to some real savings.

Overclocking a GPU is a less common process than overclocking a CPU, and above all, it’s more complex. One of the reasons for that is that a graphics card’s BIOS is not as easily accessible as a motherboard’s. This article will shed some light on the different methods that can be used and the results you can expect when overclocking your graphics card.

I OC'ed my HD2900Pro 1GB to a 850MHz GPU (from 600MHz) and 2250MHz memory (from 1850MHz). So I technically got alomost a 50% OC. But mine is just a HD2900XT 1GB just down clocked.

The HP disk utility asks me for DOS files to write to the disk where would I find these?

Better than the "Overclock your card in 5 minutes" article.

By the way, the first step in Nibitor is to select the device, before you can read the BIOS ;) I'd like to know how you "deleted" the "Extra" frequencies. Did you set them to 0 or did you actually set the number of performance levels to 3 instead?
