BIOS Setup

Frequency/Voltage Control

This section describes how to set the Chassis Intrusion feature, CPU FSB
frequency, monitor the current hardware status including CPU/system
temperatures, CPU/System Fan speeds, Vcore etc. Monitor function is avail-
able only if there is hardware monitoring mechanism onboard.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
Auto Detect PCI Clock
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, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be-
cause even a slight jitter can introduce a temporary boost in clockspeed which
