Config (Configure) TDP (Available when SpeedStep is set to Enable)
Use this feature to set the appropriate TDP (Thermal Design Power) level for the system.
The TDP refers to the maximum amount of power allowed for running "real applications"
without triggering an overheating event. The options are Normal, Level 1, and Level 2.
Activate PBF (Available when SpeedStep is set to Enable)
PBF (Priorituzed Base Frequency) is an Intel CPU Speed Select feature that is supported
on some models of the CPU. Speed Select is the ability to increase base frequency on
certain cores (High Priority cores) in exchange for lowering the base frequency on rest of
a CPU's cores (low Priority cores). When enable on supported CPUs, it will allow the user
to activate the speed select feature. The options are Enable and Disable.
Configure PBF (Available when Activate PBF is set to Enable)
Select Enable to allow the BIOS to configure high priority CPU cores as Prioritized Base

Base Frequency) settings. The options are Enable and Disable.
EIST PSD Function (Available when SpeedStep is set to Enable)
Use this item to configure the processor's P-State coordination settings. During a P-State,
the voltage and frequency of the processor will be reduced when it is in operation. This
makes the processor more energy efficient, resulting in further energy gains. The options
are HW_ALL, SW_ALL, and SW-ANY.
Turbo Mode (Available when SpeedStep is set to Enable)
It raises the clock frequency of the processor to a manufacturer defined turbo speed beyong
the stock frequency when CPU is under load. The predefined turbo speed can be found
