Option Description 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 NOTE: If there are four processors installed in the system, you will see an entry for Number of Turbo Boost Enabled Cores for Processor 4. Controls the number of turbo boost enabled cores for Processor 1. The maximum number of cores is enabled by default. Monitor/Mwait 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 Power Management Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to Enabled by default. 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 Controls the tuning function for Quality of Service (QoS) knobs. Disabled by default. Method 1 is recommended for 2-2-2 memory configurations in App-Direct. Method 2 is recommended for other memory configurations in App-Direct. Method 3 is recommended for 1 DIMM per channel configurations. Intel Persistent Memory Performance Setting Controls the thresholds that trigger switching between near (RDIMM/LRDIMM) and far (DCPMM) memory. BW Optimized, selected by default, optimizes for RDIMM/LRDIMM and DCPMM bandwidth. Latency Optimized offers better RDIMM/LRDIMM latency in the presence of DCPMM. Balanced Profile optimizes performance with Memory Mode-configured DCPMM. System Security You can use the System Security screen to perform specific functions such as setting the system password, setup password and disabling the power button. Viewing System Security To view the System Security screen, perform the following steps: Steps 1. Turn on, or restart your system. 2. Press F2 immediately after you see the following message: F2 = System Setup NOTE: If your operating system begins to load before you press F2, wait for the system to finish booting, and then restart your system and try again. 3. On the System Setup Main Menu screen, click System BIOS. 4. On the System BIOS screen, click System Security. 34 Pre-operating system management applications
