Auto Dsable PCI Frequency
When set to [Enabled], the system wll remove (turn o󰘯) clocks from empty PCI slots to
mnmze the electromagnetc nterference (EMI).
CPU Voltage (V)/ CPU_VTT Voltage(V)/ GPU Voltage (V)/ DRAM Voltage (V)/ PCH
1.05(V)
These tems are used to adjust the voltage of CPU, Memory and chpset.
Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced
to 󰘱atter curves.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
jtter can ntroduce a temporary boost n clock speed whch may just cause your over
-
clocked processor to lock up.
