Ths field allows you to select the PCIE frequency (n MHz).

Auto Dsable DIMM/PCI Frequency

When set to [Enabled], the system wll remove (turn off) clocks from empty DRAM/ PCI

slots to mnmze the electromagnetc nterference (EMI).

DRAM Voltage (V)/ NB Voltage (V)/ SB Voltage (V)

These tems are used to adjust the voltage of 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

optmal 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.
