OK, then both overclocking programs CPUFSB & ATiTool should work fine for you on XP Home!
Btw, I was able to get my ATi 9550 / 256bit / 256mb AGP card to these (Stable) clock speeds using ATiTool.
GPU: 460Mhz
RAM: 243Mhz

And as you saw in the last post overclocked my P4-B 2.4Ghz to 2.68Ghz.
Yea, doing this really helped out my old system & gave it better response time & better gaming as well!
I was able to play HL2, FEAR, Doom3, COD2, FarCry, Quake4, Chronicles of Riddick, etc on this system with both the CPU & graphics card overclocked.
Ran it like this for years with no problems at all.
