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

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.

Number of Turbo Boot Enabled Cores for Processor 1
