Frequency/Voltage Control
The settings on the screen are for reference only. Your version may not be identical to this one.
CPU Clock Ratio
This field is used to select the CPU's frequency ratio.
Important: The frequency ratio of some processors may have been locked by
the manufacturer. If you are using this kind of processor, setting a frequency
ratio for the processor will have no effect. The system will instead use its factory
default ratio.
Spread Spectrum
Leave this field in its default setting. Do not alter this setting unless
advised by an engineer or technician.
