If your video card is NVIDIA chipset(all TNT, Geforce series) then here is a simple and FREE way to overclock your video card. :)

Actually NVIDIA graphic driver has overclocking function, but it is hidden as default. The methods here is open the hidden function to allow us overclock the frequencie of graphic card’s GPU and memory.
