3 ► PCI Express Clock This option is used to adjust the speed of PCI Express slot. It may enhance the graphics card speed. ► CPU Multiplier Adjust (Optional only if CPU supports) This option is used to adjust the CPU Clock Ratio. Multiply CPU clock with this ratio, you can get the CPU speed. Increase this ratio may overclock your CPU. This option will be displayed only if your CPU is supporting this feature. ► Spread Spectrum If you enabled this function, it can significantly reduce the EMI (Electromagnetic Interference) generated by the system, so to comply with FCC regulation. But if overclocking is activated, you had better disable it. Voltage Options CMOS Setup Utility - Copyright (C) 1985-2006, American Megatrends, Inc.
