System Profile Settings screen
You can use the System Profile Settings screen to enable specific system performance settings such as
power management.
You can view the System Profile Settings screen by clicking System Setup Main Menu → System BIOS →
System Profile Settings.
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.
NOTE: The following parameters are available only when the System
Profile is set to Custom.
CPU Power Management Sets the CPU power management. By default, the CPU Power
Management option is set to System DBPM (DAPC). 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.
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 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.
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
Performance Control
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.
Memory Patrol Scrub Sets the memory patrol scrub frequency. By default, the Memory Patrol
Scrub option is set to Standard.
Memory Refresh Rate Sets the memory refresh rate to either 1x or 2x. By default, the Memory
Refresh 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 Policy Enables you to 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.
