Overclockng

Current CPU / DRAM Frequency

These tems show the current clocks of CPU and Memory speed. Read-only.

CPU Base Frequency

Ths tem s used to adjust the CPU base frequency (n MHz).

Adjust PCI-E Frequency (MHz)

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

OC Gene Button Operaton

Ths eld s used to enable/ dsable OC Gene functon.

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.
