Spread Spectrum Modulated
When the motherboard clock generator pulses, the extreme values (spikes)

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 Disabled for optimal system
stability and performance. But if you are plagued by EMI, setting to En-
