Tools for graffics card overclocking:
RivaTuner
PowerStrip
RadClocker (ATI Only)
ATITool (ATI only)
NVMax (nVidia only)
CoolBits (nVidia only)
RivaTuner and Powerstrip are two of the best.
Learn how to use whichever program you have downloaded and open it. First work on either the core clock or the memory clock. Not both simultaneously. We do this so that when we see artifacts, we know which clock speed is causing them. We will start w/ the core. Increase your core speed by around 10mhz at a time. Then apply your new clock speed. Then look for any artifacts (funky lines, colors, static, etc). There is a slight chance that your system will reboot after increasing your speed. If so, try a lower increase. If everything looks normal, increasing again by 10mhz. Do this until you start seeing artifacts on your screen. Then lower your clock back down the minimum that you can until they go away. Once you think you're close to your max core clock speed that is free from artifacts, test that speed w/ a game. If there are no artifacts there either, your good. If there are artifacts in the game, decrease your speed until there go away. Now you have found your max core clock speed.
Now do the same steps w/ your memory clock speed.
Now that you have found your max speeds, you should have the option to apply those speeds everytime Windows boots. Note that later on you may try a different game and see some artifacts or start to see some after 30min of straight gaming. In this case, you'll have to play around w/ your speeds to figure out whether it's your core or memory clock that's causing the artifacts. Just adjust accordingly.

DDR, totally didn't think of the meaning of DDR. LOL.
