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.
Settings: [Disabled, +/- 0.1%, +/- 0.2%, +/- 0.3%, +/- 0.4%, +/- 0.5%, +/-
0.6%, +/- 0.7%, +/- 0.8%, +/- 0.9%]
