Use this menu to specify your settings for frequency/voltage control.

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.

DRAM Frequency

Use this field to configure the clock frequency of the installed DRAM. Settings

are: PSB 400: 266, Auto.

PSB 533: 266, 333, Auto, 354.

PSB 800: 266, 333, 400, Auto, 500, 532.

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 No 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.
