Auto Detect PCI Clk

Settings: [Enabled, Disabled]

Spread Spectrum

When the mainboard's clock generator pulses, the extreme values (spikes) of the
pulses create 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.
