Menu Item Descriptionlogical processor per core. By default, the Logical Processoroption is set to Enabled.Alternate RTID (Requestor TransactionID) SettingEnables you to allocate more RTIDs to the remote socket,thereby increasing cache performance between the socketsor easing work in normal mode for NUMA. By default, theAlternate RTID (Requestor Transaction ID) Setting is set toDisabled.Virtualization Technology Enables or disables the additional hardware capabilitiesprovided for virtualization. By default, the VirtualizationTechnology option is set to Enabled.Address Translation Service (ATS) Defines the Address Translation Cache (ATC) for devices tocache the DMA transactions. This field provides an interfaceto a chipset's Address Translation and Protection Table totranslate DMA addresses to host addresses. By default, theoption is set to Enabled.Adjacent Cache Line Prefetch Optimizes the system for applications that require highutilization of sequential memory access. By default, theAdjacent Cache Line Prefetch option is set to Enabled. Youcan disable this option for applications that require highutilization of random memory access.Hardware Prefetcher Enables or disables the hardware prefetcher. By default, theHardware Prefetcher option is set to Enabled.DCU Streamer Prefetcher Enables or disables the Data Cache Unit (DCU) streamerprefetcher. By default, the DCU Streamer Prefetcher option isset to Enabled.DCU IP Prefetcher Enables or disables the Data Cache Unit (DCU) IP prefetcher.By default, the DCU IP Prefetcher option is set to Enabled.Execute Disable Enables or disables the execute disable memory protectiontechnology. By default, the Execute Disable option is set toEnabled.Logical Processor Idling Enables or disables the operating system capability to putlogical processors in the idling state in order to reduce powerconsumption. By default, the option is set to Disabled.Configurable TDP Allows reconfiguration of Thermal Design Power (TDP) tolower levels.TDP refers to the maximum amount of power the coolingsystem is required to dissipate.X2Apic Mode Enables or disables the X2Apic mode.Number of Cores per Processor Controls the number of enabled cores in each processor. Bydefault, the Number of Cores per Processor option is set toAll.24
