CPU Voltage Frequency [Auto]
Frequency switching affects the VRM transient response, and the thermal component.
Higher frequency gets quicker transient response.
Conguration options: [Auto] [Manual]
DO NOT remove the thermal module when switching to Manual Mode. The thermal
conditions should be monitored.
VRM Spread Spectrum [Disabled]
This item appears only when you set the Frequency item to [Auto] and allows you to
