There are mound, heaps and piles of GPU (graphic processing unit) overclocking software available on the internet. Below is the step by step process by which I have found my successful overclocks:
1. The first thing you want to do is locate the latest and/or best drivers for your particular video card. These can be from ATI's website ( http://www.ati.com/support/driver.html ) or my personal favorite ( www.omegadrivers.net ), the latter which is an easy way to get quality overclocking software as well as quality modified drivers.
2. Now on to the downloading. You need to pick out some software. In my opinion, the necessaries are ATI Tool ( www.guru3d.com ) and radlinker (also at guru3d.com or comes with omega drivers).
3. On to overclocking. Our first step will be to install ATI Tool, and then use that to find your clocks. You can use the automatic highest core and mem button if you have the time, takes about 4 hours. If not, you can adjust the values yourself.
4. Adjusting the values: The first step is to open the 3D window, so you can see the spinning cube. This will allow you to watch for artifacts, little white dots that mean your GPU is heating up too much. Now, start moving the two sliders up about 5Mhz at a time. Keep doing this until dots begin to appear on the cube. Stop, and lower the memory slider until the dots dissappear. You should now be able to continue moving the core slider until more dots appear. When they do, lower the core slider until they are gone, then press the 'Scan for Artifacts' button. Let the artifact test run until either the 'no errors' timer resets, you start to see artifacts, or it has run for 10 min to an hour with no problems. If the first two conditions occur, lower the mem, and or core a little and try the test again. Repeat until you have a stable overclock.
5. Now that you have a stable overclock, you are going to apply it to your system using radlinker. I do this because I have had in game problems while using both ATI Tool and Rivatuner, and radlinker is invisible and efficient. To do this, install radlinker then right click on the desktop, select the radlinker button, and on the window that pops up select "Enable Clock Rate Change". Move these memory sliders until you have set the same values we found with ATI Tool. Once you have done this, click the "Use Current" button, then click "Apply" and "Ok". You have just successfully overclocked your GPU, and the settings will automatically come into play as soon as you start boot into windows. All that is left now is to uninstall ATI Tool and start playing games.
Good luck!
EDIT: The latest versions of ATI Tool have fixed many compatibility errors, so it is not necessary to use Radlinker if you do not want. ATI tool is quite sufficient to maintain any overclock you may want. It also now comes with many neat features such as a temperature monitor and dynamic fan control for your video card.
