How to Overclock Your Video Card
Making Changes Permanent (ATI-Based Cards)
Contents
The process for ATI-based cards is similar, but you will need to use different programs: RaBiT, which is a BIOS editor, and ATIWinFlash, which is a BIOS programmer.
Run ATIWinFlash and first backup the BIOS your video card is currently using. If in the future you want to restore your video card’s original BIOS, just update your video card BIOS with this file. Click on Save to save your video card BIOS to a file.

Then run RaBiT and open the BIOS file by going to Open, BIOS file. Click on the Clocking tab to edit the core and memory clocks. After editing these two fields, save the BIOS into a new file by clicking on Save As. Now you have your overclocked BIOS saved to a file.

Run ATIWinFlash again, click on Load Image, and select your overclocked BIOS file. Click on Program, and ATIWinFlash will save your overclocked BIOS to your video card.
Restart your computer and your work is done.
