Menu Item Description
System Profile Sets the system profile. If you set the System Profile option to a mode other than
Custom, the BIOS automatically sets the rest of the options. You can only change
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.
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.
Memory Sets the speed of the system memory. You can select Maximum Performance,
Frequency Maximum Reliability, or a specific speed.
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 Enables or disables the Energy Efficient Turbo.
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.
C1E 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.
Collaborative CPU Enables or disables the CPU power management. When set to Enabled, the CPU
Performance power management is controlled by the OS DBPM and the System DBPM (DAPC).
Control By default, the option is set to Disabled.
Memory Patrol Sets the memory patrol scrub frequency. By default, the Memory Patrol Scrub
Scrub option is set to Standard.
Memory Refresh Sets the memory refresh rate to either 1x or 2x. By default, the Memory Refresh
Rate Rate option is set to 1x.
Uncore Frequency 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.
Energy Efficient Selects the Energy Efficient Policy.
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: The following parameters are available only when the System Profile is
set to Custom.
