Ratio Change
This field allows you to select the CPU Ratio. Setting to [Auto] enables CPU Ratio
automatically to be determined by SPD. Setting options: [Auto], [Manual].
Adjust CPU Ratio
When the Ratio Change is set to [Manual], the field is adjustable. This item allows
you to adjust the CPU ratio. It is available only when the processor supports this
function.
Auto Disable PCI Clock
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 inter-
ference (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. Setting options: [Disabled], [Enabled].
