The System Profile Settings screen details are explained as follows:ExampleMenu Item DescriptionSystem Profile Sets the system profile. If you set the System Profile option to a mode other thanCustom, the BIOS automatically sets the rest of the options. You can only changethe rest of the options if the mode is set to Custom. By default, the System Profileoption is set to Performance Per Watt Optimized (DAPC). DAPC is Dell ActivePower Controller.NOTE: The following parameters are available only when the System Profile isset to Custom.CPU PowerManagementSets the CPU power management. By default, the CPU Power Management optionis set to System DBPM (DAPC). DBPM is Demand-Based Power Management.MemoryFrequencySets 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, theTurbo Boost option is set to Enabled.Energy EfficientTurboEnables or disables the Energy Efficient Turbo.Energy Efficient Turbo (EET) is a mode of operation where a processor’s corefrequency is adjusted within the turbo range based on workload.C1E Enables or disables the processor to switch to a minimum performance state whenit 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. Bydefault, the C States option is set to Enabled.Collaborative CPUPerformanceControlEnables or disables the CPU power management. When set to Enabled, the CPUpower management is controlled by the OS DBPM and the System DBPM (DAPC).By default, the option is set to Disabled.Memory PatrolScrubSets the memory patrol scrub frequency. By default, the Memory Patrol Scruboption is set to Standard.Memory RefreshRateSets the memory refresh rate to either 1x or 2x. By default, the Memory RefreshRate option is set to 1x.Uncore Frequency Selects the Processor Uncore Frequency.Dynamic mode allows the processor to optimize power resources across the coresand uncore during runtime. The optimization of the uncore frequency to eithersave power or optimize performance is influenced by the setting of the EnergyEfficiency Policy.Energy EfficientPolicySelects the Energy Efficient Policy.The CPU uses the setting to manipulate the internal behavior of the processor anddetermines whether to target higher performance or better power savings.39
