Auto Detect PCI Clk:
When enabled the mainboard automatically disables the clock source for a
PCI slot which does not have a module in it, reducing EMI (ElectroMagnetic
Interference).
Spread Spectrum Modulated:
If you enable spread spectrum, it can significantly reduce the EMI
(ElectroMagnetic Interference) generated by the system.
