Hi, sorry for my very-very late reply.
My old noteboook using AMD turion with nVidia 6100 Chipset.
Im not using setFSB or other software to overclock the CPU accept nVidia System tools V6.06.
First install the nvidia chipset and graphic driver, reboot then install nvidia system tools, reboot.
Open the nvidia system tools, you will found the FSB slide bar. Increase or decrease this to overclock your CPU.
I notice only this bar working with my acer notebook running on WinXP32. SPD, CPUratio not working.
Hope this will help U.
