These tems are used to adjust the voltage of CPU, Memory and chpset.
▶ 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. If you do not have any EMI problem, leave the settng at Dsabled for opt-
mal system stablty and performance. But f you are plagued by EMI, set to Enabled for
EMI reducton. 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 overclocked processor to lock up.
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.
