Option 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. This option is set toPerformance Per Watt Optimized (DAPC) by default. DAPC is Dell Active PowerController.NOTE: All the parameters on the system profile setting screen available onlywhen the System Profile option is set to Custom.CPU PowerManagementSets the CPU power management. This option is set to System DBPM (DAPC) bydefault. 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. This option isset to Enabled by default.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. This option is set to Enabled by default.C States Enables or disables the processor to operate in all available power states. Thisoption is set to Enabled by default.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).This option is set to Disabled by default.Memory PatrolScrubSets the memory patrol scrub frequency. This option is set to Standard by default.Memory RefreshRateSets 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.Dynamic mode enables the processor to optimize power resources across thecores and uncore during runtime. The optimization of the uncore frequency toeither save power or optimize performance is influenced by the setting of theEnergy Efficiency Policy.Energy EfficientPolicyEnables you to select 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.Number of TurboBoot EnabledCores forProcessor 1NOTE: If there are two processors installed in the system, you see an entry forNumber of Turbo Boost Enabled Cores for Processor 2.Controls the number of turbo boost enabled cores for processor 1. The maximumnumber of cores is enabled by default.40
