Menu Item DescriptionMemory Operating Mode Specifies the memory operating mode. The options available areOptimizer Mode, Advanced ECC Mode, Mirror Mode, Spare Mode,Spare with Advanced ECC Mode, and Dell Fault Resilient Mode. Bydefault, the Memory Operating Mode option is set to Optimizer Mode.NOTE: The Memory Operating Mode can have different defaultsand available options based on the memory configuration of yoursystem.NOTE: The Dell Fault Resilient Mode establishes an area of memorythat is fault resilient. This mode can be used by an operating systemthat supports the feature to load critical applications or enables theoperating system kernel to maximize system availability.Node Interleaving If this field is Enabled, memory interleaving is supported if a symmetricmemory configuration is installed. If Disabled, the system supports Non-Uniform Memory architecture (NUMA) (asymmetric) memoryconfigurations. By default, Node Interleaving option is set to Disabled.Snoop Mode Snoop Mode options available are Disabled, Home Snoop, Early Snoop,Cluster on Die. By default, the Snoop Mode option is set to Disabled. Thefield is only available when Node Interleaving is Disabled.Processor Settings screenYou can use the Processor Settings screen to view the processor settings and perform specific functionssuch 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.Menu Item DescriptionLogical Processor Enables or disables the logical processors and displays the number oflogical processors.

By default, the Virtualization Technology option is set toEnabled.Address Translation Service(ATS)Defines the Address Translation Cache (ATC) for devices to cache theDMA transactions. This field provides an interface to a chipset's AddressTranslation and Protection Table to translate DMA addresses to hostaddresses. By default, the option is set to Enabled.Adjacent Cache LinePrefetchOptimizes the system for applications that require high utilization ofsequential memory access. By default, the Adjacent Cache Line Prefetchoption is set to Enabled. You can disable this option for applications thatrequire high utilization of random memory access.20
