LVDS Spread Spectrum
When the motherboard clock generator pulses, the extreme values (spikes) of the pulses creates
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 you do not
have any EMI problem, leave the setting at Off for optimal system stability and performance.
