Menu Item DescriptionRedirection After Boot Enables or disables the BIOS console redirection when the operatingsystem is loaded. By default, the Redirection After Boot option is set toEnabled.System Profile Settings screenYou can use the System Profile Settings screen to enable specific system performance settings such aspower management.To view the System Profile Settings click System Setup Main Menu → System BIOS → System ProfileSettings.Menu Item DescriptionSystem Profile Sets the system profile. If you set the System Profile option to a modeother 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 WattOptimized (DAPC). DAPC is Dell Active Power Controller.NOTE: The following parameters are available only when the SystemProfile is set to Custom.CPU Power Management Sets the CPU power management. By default, the CPU PowerManagement 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 MaximumPerformance, Maximum Reliability, or a specific speed.Turbo Boost Enables or disables the processor to operate in turbo boost mode. Bydefault, 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’score frequency is adjusted within the turbo range based on workload.C1E Enables or disables the processor to switch to a minimum performancestate 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 CPUPerformance ControlEnables or disables the CPU power management. When set to Enabled,the CPU power management is controlled by the OS DBPM and theSystem DBPM (DAPC). By default, the option is set to Disabled.Memory Patrol Scrub Sets the memory patrol scrub frequency. By default, the Memory PatrolScrub option is set to Standard.Memory Refresh Rate Sets the memory refresh rate to either 1x or 2x. By default, the MemoryRefresh Rate option is set to 1x.Uncore Frequency Selects the Processor Uncore Frequency.Dynamic mode allows the processor to optimize power resources acrossthe cores and uncore during runtime. The optimization of the uncorefrequency to either save power or optimize performance is influenced bythe setting of the Energy Efficiency Policy.27
