Menu Item Description logical processor per core. By default, the Logical Processor option is set to Enabled. Alternate RTID (Requestor Transaction ID) Setting 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. Virtualization Technology Enables or disables the additional hardware capabilities provided for virtualization. By default, the Virtualization Technology option is set to Enabled. Address Translation Service (ATS) Defines the Address Translation Cache (ATC) for devices to cache the DMA transactions. This field provides an interface to a chipset's Address Translation and Protection Table to translate DMA addresses to host addresses. By default, the option is set to Enabled. Adjacent Cache Line Prefetch 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. Hardware Prefetcher Enables or disables the hardware prefetcher. By default, the Hardware Prefetcher option is set to Enabled. DCU Streamer Prefetcher Enables or disables the Data Cache Unit (DCU) streamer prefetcher. By default, the DCU Streamer Prefetcher option is set 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 protection technology. By default, the Execute Disable option is set to Enabled. Logical Processor Idling Enables or disables the operating system capability to put logical processors in the idling state in order to reduce power consumption. By default, the option is set to Disabled. Configurable TDP Allows reconfiguration of Thermal Design Power (TDP) to lower levels. TDP refers to the maximum amount of power the cooling system is required to dissipate. X2Apic Mode Number of Cores per Processor Enables or disables the X2Apic mode. Controls the number of enabled cores in each processor. By default, the Number of Cores per Processor option is set to All. 24
