Hardware Monitor Setup

This section describes how to set the CPU FSB frequency, monitor the current
hardware status including CPU/system temperatures, CPU/System Fan speeds,
Vcore etc. Monitor function is available 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.
CPU FSB Clock (Mhz)
This setting allows you to select the CPU Front Side Bus clock frequency.
Setting options:
CPU FSB
100MHz
133MHz
Spread Spectrum
When the motherboard clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
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
Setting Range
100MHz~200MHz at 1MHz increment
133MHz~233MHz at 1MHz increment
