Spread Spectrum
When the mainboard's clock generator pulses, the extreme values
(spikes) of the pulses create EMI (Electromagnetic Interference).
The Spread Spectrum function reduces the EMI generated by
modulating the pulses so that the spikes of the pulses are reduced
to flatter curves. If the system is not placed near EMI sensitive
electronics, it is recommended to leave this feature disabled.
