Frequency/Voltage Control - MSI MS-7021 Manual

BIOS Setup

Frequency/Voltage Control

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 Disabled for optimal system stability and
performance. But if you are plagued by EMI, select Enabled for EMI reduction.
Remember 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. Available options: Enabled,
Disabled.
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.
CPU Ratio/Vcore (V)
The settings are used to adjust the CPU clock multiplier (ratio) and CPU
corevoltage (Vcore). These settings offer users a tool to overclock the system.
