Energy Efficient Turbo (EET) is a mode of operation where a processor’s core frequency is adjusted to be
within the turbo range based on workload.
C1E Enables or disables the processor to switch to a minimum performance state when it is idle. This option is
set to Enabled by default.
C States Enables or disables the processor to operate in all available power states. This option is set to Enabled by

Uncore
Frequency
Enables you to select the Processor Uncore Frequency option.
Dynamic mode enables the processor to optimize power resources across the cores and uncore during
runtime. The optimization of the uncore frequency to either save power or optimize performance is
influenced by the setting of the Energy Efficiency Policy option.
Energy Efficient
Policy
Enables you to select the Energy Efficient Policy option.
The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to
target higher performance or better power savings.

Cores for
Processor 1
NOTE: If there are two processors installed in the system, you see an entry for Number of Turbo
Boost Enabled Cores for Processor 2.
Controls the number of turbo boost enabled cores for processor 1. The maximum number of cores is
enabled by default.
Monitor/Mwait Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for all system
profiles, except Custom by default.
NOTE: This option can be disabled only if the C States option in the Custom mode is set to
