► CPU Frequency Multiplier
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 valid if
your CPU ratio is unlocked and 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
► CPU Voltage Control
This option is used to change the CPU voltage in a step of 25mV. The voltage can be
incremented from +25mV to +775mV.
► Memory Voltage Control
This option is used to change the DRAM voltage in a step of 50mV. The voltage can be
incremented from +50mV to +600mV.
► NB Voltage Control
This option is used to change the North Bridge voltage in a step of 30mV. The voltage can be
incremented from +30mV to +360mV.
► HT/SB Voltage Control HT/SB Voltage Control
This option is used to change the HT/SB voltage in a step of 30mV. The voltage can be
incremented from +30mV to +360mV.
