Frequency/Voltage Control - MSI MS-6764 User Manual

MS-6764 ATX Mainboard

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, setting 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 clockspeed
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.
CPU Ratio/Vcore (V)
The settings are used to adjust the CPU clock multiplier (ratio) and CPU core
voltage (Vcore). These settings offer users a tool to overclock the system.
