Overclocking the Video Card

• Atitool - Made by W1zzard here at techpowerup, is an excellent tool for overclocking and modifying ATI video cards. Some Nvidia support is being included.
• Rivatuner - An excellent video card overclocking tool.
• Powerstrip - An excellent universal overclocking tool.
• coolbits - A driver addition found in NVIDIA’s drivers, it allows changing the core and memory speeds of your GPU.

Overclocking a video card is rather simple. It is primarily done from within windows, accomplished through the use of usually one of the programs listed above. Like a motherboard, video cards have bios as well. However, it is not as easily accessible as a motherboards bios, and must be altered before flashing. It is not intended for the end user to be modifying, and therefore is not easy to change. Video bios’ flashing is sometimes required for pipeline mods, fixing an operating conflict, and manually changing the clock speeds to a preset overclocked speed.
