Hack 73 Overclock Your ATI Radeon 
Perhaps the simplest and safest way to
determine and set the highest speeds for your ATI
adapters.
The easiest and safest way I found to kick up your
ATI video adapter and get a
performance increase is with a nicely written, easy-to-use program
called ATITool, shown in Figure 7-6.

It is available for download from http://www.techpowerup.com/atitool/. ATITool
is known to overclock cards with the ATI Radeon 9000, 9200, 9500,
9600, 9700, and 9800 chips, but it should work on other older ATI
cards as well. ATITool will test your adapter for both the maximum
core video processor speed and the highest memory speed your card
will work at reliably. When it finds the fastest and safest values,
you can store them away, lock them into the adapter, and have them
set every time you boot your PC.
Before overclocking, an ATI Radeon 7000-based video card running at
its default 183 MHz core and memory clock speeds in a 533 MHz Pentium
III ran at an average of 13.6 fps. Overclocking by 10.3% to 202 MHz
provided a performance increase of 12%.
