the rest of the options if the mode is set to Custom. By default, the System Profile

 

option is set to Performance Per Watt Optimized (DAPC). DAPC is Dell Active

 

Power Controller.

 

NOTE: The following parameters are available only when the System Profile is

 

set to Custom.

CPU Power

Sets the CPU power management. By default, the CPU Power Management option

Management

is set to System DBPM (DAPC). DBPM is Demand-Based Power Management.

Turbo Boost

Enables or disables the processor to operate in turbo boost mode. By default, the

 

Turbo Boost option is set to Enabled.

Energy Efficient Turbo

C1E

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.

C States

Enables or disables the processor to operate in all available power states. By

 

default, the C States option is set to Enabled.

Memory DDR Freq Max performance is enabled.

Number of Turbo Boot Enabled Cores for Processor 1

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.

Selects 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.

Selects 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.
