The System Profile Settings screen details are explained
as follows:
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.
Memory Frequency
Sets the speed of the 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.
Collaborative CPU Performance Control
Enables or disables the CPU power management option.
When set to Enabled, the CPU power management is controlled
by the OS DBPM and the System DBPM (DAPC). This option is set to Disabled by default.
Memory Patrol Scrub
Sets the memory patrol scrub frequency. This option
is set to Standard by default.
Memory Refresh Rate
Sets the memory refresh rate to either 1x or 2x. 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
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
NOTE: If there are two processors installed in the system, you see an
entry for Number of Turbo Boost Enabled Cores for Processor
2.
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 Enabled for all system
profiles, except Custom by default.
NOTE: This option can be
disabled only if the C States option in the Custom mode is set to disabled.
NOTE: When C States is set to Enabled in
the Custom mode, changing the Monitor/Mwait
setting does not impact the system power or performance.
