Description
Select whether to enable Enhanced Intel SpeedStep Technology.
EIST allows a compliant OS to dynamically adjust the processor
voltage and core frequency based on system usage. This can
result in decreased average power consumption and decreased
average heat production.
Note: After enabling EIST in BIOS Setup, you need to enable it
on your operating system as well. Consult your OS
documentation for related instructions.
Select whether to enable the Intel Turbo Boost technology. When
enabled, the processor can maximize its core frequency while
ensuring that it does not exceed its electrical and thermal
specifications.
Note: The number of active processor cores dictates the upper
limit of Intel Turbo Boost technology.
Select whether to enable Enhanced Halt State. When enabled, a
halt state is invoked during the OS idle period. This turns down
the processor clock frequency (via multiplier control) resulting in
lower power consumption.
Select the preferred state for the processor core in C3 state (_CST
as an ACPI C2/C3 state).
Select the preferred state for the processor core in C6 state (_CST
as an ACPI C3 state).
