Menu Item System Memory Voltage Video Memory System Memory Testing Memory Operating Mode Description Displays the system memory voltage. Displays the amount of video memory. Specifies whether system memory tests are run during system boot. Options are Enabled and Disabled. By default, the System Memory Testing option is set to Disabled. Specifies the memory operating mode. By default, the Memory Operating Mode option is set to Optimizer Mode. NOTE: The Memory Operating Mode can have different defaults and available options based on the memory configuration. Node Interleaving Serial Debug Output If this field is Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If Disabled, the system supports Non-Uniform Memory architecture (NUMA) (asymmetric) memory configurations. By default, Node Interleaving option is set to Disabled. By default, it is set to disabled. Processor Settings Screen Menu Item Logical Processor QPI Speed Description Allows you to enable or disable logical processors and display the number of logical processors. If the Logical Processor option is set to Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS only displays one logical processor per core. By default, the Logical Processor option is set to Enabled. Allows you to set the QuickPath Interconnect data rate settings. By default, the QPI Speed option is set to Maximum data rate. NOTE: The QPI speed option displays only when both the processors are installed. Alternate RTID (Requestor Transaction ID) Setting Allows you to allocate more RTIDs to the remote socket increasing cache performance between the sockets or work in normal mode for NUMA. By default, the Alternate RTID (Requestor Transaction ID) Setting is set to Disabled. Virtualization Technology Allows you to enable or disable the additional hardware capabilities provided for virtualization. By default, the Virtualization Technology option is set to Enabled. Adjacent Cache Line Prefetch Allows you to optimize the system for applications that require high utilization of sequential memory access. By default, the Adjacent Cache Line Prefetch option is set to Enabled. You can disable this option for applications that require high utilization of random memory access. Hardware Prefetcher Allows you to enable or disable hardware prefetcher. By default, the Hardware Prefetcher option is set to Enabled. DCU Streamer Prefetcher Allows you to enable or disable Data Cache Unit streamer prefetcher. By default, the DCU Streamer Prefetcher option is set to Enabled.
