Frequency/Voltage Control

This section controls the frequency/voltage of the CPU and certain onboard

hardware to enhance overall system performance.

CPU Ratio Selection

This setting controls the multiplier that is used to determine the internal clock

speed of the processor relative to the external or motherboard clock speed.

Auto Detect DIMM/PCI Clock

This item is used to auto detect the DIMM/PCI slots. When set to Enabled,

the system will remove (turn off) clocks from empty DIMM/PCI slots to mini-

mize the electromagnetic interference (EMI). Setting options: Enabled, Disabled.

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, activate the Spread Spectrum 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.
