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: 100MHz~200MHz at 1MHz increment.

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

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
