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

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
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.
