Info on overclocking wanted

ok here is a detailed summary of this system, the board supports 2 cpus but has only one installed, im am wondering if it is possible to overclock the coppermine piii or FSB
I am not knowledgeable about adjusting any settings via a program such as CPUCool so a point in the right direction would be greatly appreciated
