CPU Spread Spectrum Setting 

The CPU Spread Spectrum Setting feature enables the BIOS to modulate the 
clock frequencies originating from the mainboard. The settings are in 
percentages of modulation. Higher percentages result in greater modulation of 
clock frequencies. This feature has settings that range from 0.1% to 0.9%.
