Frequency/Voltage Control - MSI KT4A-V Instruction Manual

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 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, set to [Enabled] for EMI reduction. Remember to disable Spread Spectrum if you
are overclocking because even a slight jitter can introduce a temporary boost in clock speed 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 (in MHz) and overclock the
processor by adjusting the FSB clock to a higher frequency. Select the number between [100]~[280] for
needed frequency. The 3 default settings are: [133], [166], [200].
