generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curv
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, set to Enabled for EMI reduction. Remember to
disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a
temporary boost in clock speed which may just cause your overclocked processor to lock up.
