Adjusted HT Lnk Frequency (MHz)

It shows the adjusted HT Lnk frequency. Read-only.

Adjust PCI-E Frequency (MHz)

Ths eld allows you to select the PCIE frequency (n MHz).

Auto Dsable DIMM/PCI Frequency

When set to [Enabled], the system wll remove (turn o) clocks from empty DRAM/ PCI

slots to mnmze the electromagnetc nterference (EMI).

CPU Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ HT Lnk Voltage (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. 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, set to Enabled

for EMI reduct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 overclocked processor to lock up.

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

overclocked processor to lock up.
