BIOS Setup

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

Frequency/Voltage Control

CPU Clock Ratio

End users can overclock the processor (only if the processor supports so) by

specifying the CPU ratio (clock multiplier) in this field. It is available only when

“Set CPU Ratio” is set to Manual.

Auto Detect DIMM/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, set 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 clock speed which may just

cause your overclocked processor to lock up.

CPU Frequency

Use this item to select the appropriate clock frequency of the CPU host bus.

Options are: 100MHz, 133MHz, 200MHz, Default.
