ATI Tool is flaky. I'm glad it works for you, but I don't have the same experience. Besides, being as anal as I am about performance, the fewer apps the better.

You set ATiTool to boot ONCE during startup, which sets the 3D clocks and it automatically shuts down afterwards. It doesn't run in the background.

Or you could always use RivaTuner and set the clocks that way too.
