Option 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. This option is set to
Performance Per Watt Optimized (DAPC) by default. DAPC is Dell Active Power
Controller.
NOTE: All the parameters on the system profile setting screen are available
only when the System Profile option is set to Custom.
CPU Power
Management
Sets the CPU power management. This option is set to System DBPM (DAPC) by
default. DBPM is Demand-Based Power Management.
Memory

Sets the speed of the system memory. You can select Maximum Performance,
Maximum Reliability, or a specific speed.
Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option
is set to Enabled by default.
Energy Efficient
Turbo
Enables or disables the Energy Efficient Turbo option.
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 default.

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.
