BCLK/PCIE Ratio Configure BCLK Ratio to prevent the PC from crashing when the internal CPUclock speed and clock speed of other components are too high. Spread Spectrum Enable Spread Spectrum to reduce electromagnetic interference for passing EMI tests. Disable to achieve higher clock speeds when overclocking. Intel SpeedStep Technology Intel SpeedStep technology allows processors to switch between multiple frequencies and voltage points for better power saving and heat dissipation.
