Description
Enables or disables the processor to operate in turbo boost mode. By
default, the Turbo Boost option is set to Enabled.
Enables or disables the Energy Efficient Turbo.
Energy Efficient Turbo (EET) is a mode of operation where a processor's
core frequency is adjusted within the turbo range based on workload.
Enables or disables the processor to switch to a minimum performance
state when it is idle. By default, the C1E option is set to Enabled.
Enables or disables the processor to operate in all available power states.
By default, the C States option is set to Enabled.
Enables or disables the CPU power management. When set to Enabled,
the CPU power management is controlled by the OS DBPM and the
System DBPM (DAPC). By default, the option is set to Disabled.
Sets the memory patrol scrub frequency. By default, the Memory Patrol
Scrub option is set to Standard.
Sets the memory refresh rate to either 1x or 2x. By default, the Memory
Refresh Rate option is set to 1x.
Enables you to select the Processor Uncore Frequency.
Dynamic mode allows 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.
Enables you to select the Energy Efficient Policy.
The CPU uses the setting to manipulate the internal behavior of the
processor and determines whether to target higher performance or
better power savings.
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. By
default, the maximum number of cores is enabled.
Enables the Monitor/Mwait instructions in the processor. By default, the
Monitor/Mwait option is set to Enabled for all system profiles, except
Custom.
NOTE: This option can be disabled only if the C States option in
Custom mode is set to disabled.
NOTE: When C States set to Enabled in Custom mode, changing
the Monitor/Mwait setting does not impact system power/
performance.
