Menu Item Description NOTE: The Dell Fault Resilient Mode 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. Node Interleaving Specifies if Non-Uniform Memory architecture (NUMA) is supported. If this field is Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If Disabled, the system supports NUMA (asymmetric) memory configurations. By default, Node Interleaving option is set to Disabled. Snoop Mode Specifies the Snoop Mode options. Snoop Mode options available are Home Snoop, Early Snoop, Cluster on Die. By default, the Snoop Mode option is set to Early Snoop. The field is only available when Node Interleaving is Disabled. Processor Settings screen details You can use the Processor Settings screen to view the processor settings and perform specific functions such as enabling virtualization technology, hardware prefetcher, and logical processor idling. You can view the Processor Settings screen by clicking System Setup Main Menu → System BIOS → Processor Settings. The Processor Settings screen details are explained as follows: Menu Item Logical Processor Maximum data rate Alternate RTID (Requestor Transaction ID) Setting Virtualization Technology Address Translation Services (ATS) Adjacent Cache Line Prefetch Hardware Prefetcher DCU Streamer Prefetcher Description Enables or disables the logical processors and displays 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. QPI Speed maximum data rate 9.6 Gt/s, 8.0 GT/s, 6.4 GT/s Enables you to allocate more RTIDs to the remote socket, thereby increasing cache performance between the sockets or easing work in normal mode for NUMA. By default, the Alternate RTID (Requestor Transaction ID) Setting is set to Disabled. Enables or disables the additional hardware capabilities provided for virtualization. By default, the Virtualization Technology option is set to Enabled. Allows you to define the Address Translation Cache (ATC) for devices to cache the DMA transactions. This filed provides an interfaces to a chipset's Address Translation and Protection Table to translate DMA addresses to host addresses. By default, the option is set to Enabled. Optimizes 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. Enables or disables the hardware prefetcher. By default, the Hardware Prefetcher option is set to Enabled. Allows you to enable or disable the Data Cache Unit (DCU) streamer prefetcher. By default, the DCU Streamer Prefetcher option is set to Enabled. 126
