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

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.
C States
Enables or disables the processor to operate in all available power states. 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

1x
by default.
Uncore Frequency
Enables you to select the
Processor Uncore Frequency
option.
Dynamic mode
enables the processor to
optimize power resources across cores and uncores 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. This option is set to
Balanced Performance
by default.
Number of Turbo
Boost Enabled
Cores for
Processor 1
NOTE:
If there are four processors installed in the system, you will see an entry for Number of
Turbo Boost Enabled Cores for Processor 4.
Controls the number of turbo boost enabled cores for Processor 1. The maximum number of cores is enabled by
default.
Monitor/Mwait
Enables the Monitor/Mwait instructions in the processor. This option is set to
