Option 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.This option is set to Performance Per Watt Optimized (DAPC) by default. DAPC is Dell Active Power Controller.Other options include Performance Per Watt (OS), Performance, and Workstation Performance. NOTE: All the parameters on the system profile setting screen are available only when the System Profile option is set to Custom. CPU Power Management Sets the CPU power management. This option is set to System DBPM (DAPC) by default. DBPM is DemandBased Power Management. Other options include OS DBPM, and Maximum Performance. Memory Frequency Sets the speed of the system memory. You can select Maximum Performance, Maximum Reliability, or a specific speed. This option is set to Maximum Performance by default. Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option is set to Enabled by default. C1E Enables or disables the processor to switch to a minimum performance state when it is idle. This option is set to Enabled by default. C States Enables or disables the processor to operate in all available power states. This option is set to Enabled by default. Write Data CRC Enables or disables the Write Data CRC. This option is set to Disabled by default. Memory Patrol Scrub Sets the memory patrol scrub frequency. This option is set to Standard by default. Memory Refresh Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default. Rate Uncore Frequency Enables you to select the Processor Uncore Frequency option.Dynamic mode enables the processor to optimize power resources across cores and uncores 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 option. Energy Efficient Policy Enables you to select the Energy Efficient Policy option. The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to target higher performance or better power savings. This option is set to Balanced Performance by default. Number of Turbo Boost Enabled Cores for Processor 1 Monitor/Mwait NOTE: If there are two processors installed in the system, you will see an entry for Number of Turbo Boost Enabled Cores for Processor 2. Controls the number of turbo boost enabled cores for Processor 1. The maximum number of cores is enabled by default. Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for all system profiles, except Custom by default. NOTE: This option can be disabled only if the C States option in the Custom mode is set to disabled. NOTE: When C States is set to Enabled in the Custom mode, changing the Monitor/Mwait setting does not impact the system power or performance. CPU Interconnect Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to Enabled by default. Bus Link Power Management PCI ASPM L1 Link Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled by default. Power Management Intel Persistent Memory CR QoS Enables you to select the tunning Method 1 for QoS knobs and is recommended for 2-2-2 memory configuration in active directory, Method 2 for QoS knobs and is recommended for other memory configuration in active directory or Method 3 for QoS knobs and is recommended for 1 DIMM per channel configuration. This option is set to Disabled by default. Intel Persistent Memory Enables you to select the NVMe performance settings depending on the workload behavior. If this option is set to BW Optimized, the performance is optimized for DDR and DDRT bandwidth. If this option is set to Latency Optimized, the performance is better DDR latency. This option is set to BW Optimized by default. Pre-operating system management applications 49
