System Profile Settings screen You can use the System Profile Settings screen to enable specific system performance settings such as power management. To view the System Profile Settings click System Setup Main Menu → System BIOS → System Profile Settings. Menu Item System Profile Description 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 Memory Frequency Turbo Boost Energy Efficient Turbo Sets the CPU power management. By default, the CPU Power Management option is set to System DBPM (DAPC). DBPM is DemandBased Power Management. Sets the speed of the system memory. You can select Maximum Performance, Maximum Reliability, or a specific speed. Enables or disables the processor to operate in turbo boost mode. By default, the Turbo Boost option is set to Enabled. 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 C States Collaborative CPU Performance Control Memory Patrol Scrub Memory Refresh Rate Uncore Frequency 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. Enables or disables the processor to operate in all available power states. By default, the C States option is set to Enabled. 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. Sets the memory patrol scrub frequency. By default, the Memory Patrol Scrub option is set to Standard. Sets the memory refresh rate to either 1x or 2x. By default, the Memory Refresh Rate option is set to 1x. 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. 40

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
