BIOS Setup

Use this menu to specify your settings for frequency/voltage control.

Frequency/Voltage Control

Auto Detect PCI Clk

This option allows you to enable/disable the feature of auto detecting the clock

frequency of the installed PCI bus. The settings are: Enabled, Disabled.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)

of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-

trum function reduces the EMI generated by modulating the pulses so that the

spikes of the pulses are reduced to flatter curves. If you do not have any EMI

problem, leave the setting at Disabled for optimal system stability and

performance. But if you are plagued by EMI, activate the Spread Spectrum

for EMI reduction. Remember to disable Spread Spectrum if you are

overclocking because even a slight jitter can introduce a temporary boost in

clockspeed which may just cause your overclocked processor to lock up.

Options: Disabled, Enabled.

CPU Clock

This item specifies the clock frequency of CPU host bus (FSB), AGP (3V66)

and PCI bus. It provides a method for end users to overclock the processor.

Setting options: Give a DEC value by entering a number between maximum

200 MHz to minimum 100 MHz.
