Frequency/Voltage Control

CPU Clock Ratio

This item allows you to adjust the CPU ratio. It might be locked by CPU hardware and this item

will be hided.

Auto Detect PCI Clk

This item is used to auto detect the PCI slots. When set to [Enabled], the system will remove

(turn off) clocks from empty PCI slots to minimize the electromagnetic interference (EMI).

Settings: [Enabled], [Disabled].

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, select the desired range for EMI reduction.

Remember to disable Spread Spectrum function 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 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.
