Option Description NOTE: The Dell Fault Resilient Mode option establishes an area of memory that is fault resilient. This mode can be used by an operating system that supports the feature to load critical applications or enables the operating system kernel to maximize system availability. NOTE: Only Optimizer Mode should be selected when Intel DC Optane Persistent Memory is installed. Current State of Specifies the current state of the memory operating mode. Memory Operating Mode Node Interleaving Specifies if Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If this field is set to Disabled, the system supports NUMA (asymmetric) memory configurations. This option is set to Disabled by default. ADDDC Setting Enables or disables ADDDC Setting feature. When Adaptive Double DRAM Device Correction (ADDDC) is enabled, failing DRAM's are dynamically mapped out. When set to Enabled it can have some impact to system performance under certain workloads. This feature is applicable for x4 DIMMs only. This option is set to Enabled by default. Native tRFC Timing for 16Gb DIMMs Enables 16 Gb density DIMMs to operate at their programmed Row Refresh Cycle Time (tRFC). Enabling this feature may improve system performance for some configurations. However, enabling this feature has no effect on configurations with 16 Gb 3DS/TSV DIMMs. This option is set to Enabled by default. Opportunistic Self-Refresh Enables or disables opportunistic self-refresh feature. This option is set to Disabled by default and is not supported when DCPMM(s) are in the system. Correctable Error Enables or disables logging of correctable memory threshold error. This option is set to Enabled by default. logging Persistent Memory This field controls Persistent Memory on the system. This option is only available if the persistent memory module is installed in the system. Persistent Memory details About this task The Persistent Memory screen details can be found in the NVDIMM-N User Guide and DCPMM User Guideat www.dell.com/ poweredgemanuals. Processor Settings You can use the Processor Settings screen to view the processor settings and perform specific functions such as enabling virtualization technology, hardware prefetcher, logical processor idling. Viewing Processor Settings To view the Processor Settings screen, perform the following steps: Steps 1. Power 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 Processor Settings. Pre-operating system management applications 45
