... field allows you to select the PCIE frequency (in MHz). ▶ Auto Disable DIMM/PCI Frequency When set to adjust the voltage of memory and chipset. ▶ Spread Spectrum When the mainboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference...). If you do not have any EMI problem, leave the setting at [Disabled] for EMI reduction. • The greater the Spread Spectrum value is, the greater the EMI is reduced...
