Table 18. System Profile Settings details Option Description System Profile 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 (DAPC) by default. Other options include Performance, Performance Per Watt (OS), Workstation Performance and Custom. 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 Memory Frequency Turbo Boost C1E C States Memory Patrol Scrub Memory Refresh Rate Uncore Frequency Energy Efficient Policy Monitor/Mwait Sets the CPU power management. This option is set to System DBPM (DAPC) by default. Other option includes Maximum Performance, OS DBPM. 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. Enables or disables the processor to operate in the turbo boost mode. This option is set to Enabled by default. Enables or disables the processor to switch to a minimum performance state when it is idle. This option is set to Enabled by default. Enables or disables the processor to operate in all available power states. C States allow the processor to enter lower power states when idle. When set to Enabled (OS controlled) or when set to Autonomous (if hardware controlled is supported), the processor can operate in all available Power States to save power, but may increase memory latency and frequency jitter. This option is set to Enabled by default. Sets the memory patrol scrub mode. This option is set to Standard by default. Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default. Enables you to select the 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. 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. 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 Bus Link Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to Power Management Enabled by default. PCI ASPM L1 Link Power Management Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled by default. Processor EIST Enables or disables the PCI Processor EIST. This option is set to Enabled by default. 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 Mode 0 by default. Intel Persistent Memory Performance Setting 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 17
