BIOS Setup

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

Frequency/Voltage Control

Auto Detect DIMM/PCI Clk

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

clock frequency of the installed DIMM/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 Frequency

This option allows you to select the clock frequency of the installed CPU. The

settings are: Default, 100MHz, 133MHz, 200MHz.
