Spread Spectrum Control

This sub-menu allows you to set the CPU, PCI Express, Serial ATA, and Lightning Data Transport (LDT) clock generator spread spectrum. The spread spectrum is used to dynamically change the system frequency to minimize problems with electromagnetic interference (EMI). Set the Overclock Profile to [Manual], if you want to configure this item.
