Spread Spectrum When the motherboard'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 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, select one of the options for EMI reduction. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clockspeed which may just cause your overclocked processor to lock up. 15

Spread Spectrum
When the motherboard
’
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 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, select one of the options for EMI reduction.
Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can
introduce a temporary boost in clockspeed which may just cause your overclocked processor to
lock up.
