Hardware Monitor Setup

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
available only if there is hardware monitoring mechanism onboard.
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 En-
abled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a 0.25% jitter can introduce a temporary boost in
clockspeed of 25MHz (with a 1GHz CPU) which may just cause your
overclocked processor to lock up.
CPU FSB Clock
This item allows you to select the CPU Front Side Bus clock frequency.
Settings are 100MHz and 133MHz. If you install the 133MHz CPU, you
should change the setting to 133MHz in the field; otherwise, the CPU will
run at the default hardware configuration 100MHz.
