Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced
to flatter curves.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
jtter can ntroduce a temporary boost n clock speed whch may just cause your over-
clocked processor to lock up.
