Use this menu to specify your settings for frequency/voltage control.
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 No for optimal system stability and performance.
But if you are plagued by EMI, setting to Enabled for EMI reduction. Re-
member 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.
CPU Ratio Selection
This setting controls the multiplier that is used to determind the internal clock
speed of the processor relative to the external or motherboard clock speed.
CPU FSB Clock (Mhz)
This item allows you to select the CPU Front Side Bus clock frequency (in
MHz) and overclock the processor by adjusting the FSB clock to a higher
frequency.
