CPUcool question

[AnnexKyle]

So I was just playing around a bit with CPUcool, and I decided to play with changing my fsb/cpu speed. Well I set the pll and all that and chose the frequency I would like. But when I press 'set frequency' or 'get frequency' I get an error message saying that the pll is wrong. Can someone advise me about this?

Thanks

Some motherboards requre a change of jumpers on the actual board
to change the cpu FSB speed. Also pump it too high
and you'll have toast for breakfast.
