CPU P State Control
This feature allows the user to configure the following CPU power settings:
SpeedStep (Pstates)
Intel SpeedStep Technology allows the system to automatically adjust processor volt
-
age and core frequency to reduce power consumption and heat dissipation. The options

EIST PSD Function
This feature allows the user to choose between Hardware and Software to control the
processor's frequency and performance (P-state). In HW_ALL mode, the processor hard-
ware is responsible for coordinating the P-state, and the OS is responsible for keeping the
P-state request up to date on all Logical Processors. In SW_ALL mode, the OS Power
Manager is responsible for coordinating the P-state, and must initiate the transition on
all Logical Processors. In SW_ANY mode, the OS Power Manager is responsible for
coordinating the P-state and may initiate the transition on any Logical Processors. The
options are
HW_ALL
, SW_ALL, and SW_ANY.
Energy Efficient Turbo
Use this feature to enable or disable energy efficient turbo. The options are
Enable
