System profile screen settings
The System Profile Settings screen details are explained as follows:
Table 20. 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.
• 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. By default,
the maximum number of cores is enabled.
• Monitor/Mwait: Enables the Monitor/Mwait instructions in the processor. By
default, the Monitor/Mwait option is set to Enabled for all system profiles,
except Custom.
