This item specifies CPU frequency

266MHz

 

 

 

Spread

When the motherboard’s clock generator pulses, the

Enabled

Spectrum

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, setting to Enabled for EMI reduction.

 

 

Remember to disable Spread Spectrum if you are

 

 

overlooking because even a slight jitter can introduce

 

 

a temporary boost in clock speed which may just

 

 

cause your over lock ed processor to lock up.
