Spread Spectrum
When enabled, this option modulates the frequency of the CPU clock rate (and
hence all clock driven mainboard components), so that any EMI interference
generated is not always at the same constant frequency, but instead is spread over
a small band of frequencies, therefore reducing problems with equipment that may
be particularly sensitive to certain fixed frequencies.
