Option Descriptionlogical processor per core. By default, the Logical Processor option is set toEnabled.Alternate RTID(RequestorTransaction ID)SettingEnables you to allocate more RTIDs to the remote socket, thereby increasingcache performance between the sockets or easing work in normal mode forNUMA. By default, the Alternate RTID (Requestor Transaction ID) Setting is set toDisabled.VirtualizationTechnologyEnables or disables the additional hardware capabilities provided for virtualization.By default, the Virtualization Technology option is set to Enabled.AddressTranslationService (ATS)Defines the Address Translation Cache (ATC) for devices to cache the DMAtransactions. This field provides an interface to a chipset's Address Translation andProtection Table to translate DMA addresses to host addresses. By default, theoption is set to Enabled.Adjacent CacheLine PrefetchOptimizes the system for applications that require high utilization of sequentialmemory access. By default, the Adjacent Cache Line Prefetch option is set toEnabled. You can disable this option for applications that require high utilization ofrandom memory access.HardwarePrefetcherEnables or disables the hardware prefetcher. By default, the Hardware Prefetcheroption is set to Enabled.DCU StreamerPrefetcherAllows you to enable or disable the Data Cache Unit (DCU) streamer prefetcher. Bydefault, 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 DCUIP 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 ProcessorIdlingEnables or disables the operating system capability to put logical processors in theidling state in order to reduce power consumption. By default, the option is set toDisabled.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 todissipate.X2Apic Mode Enables or disables the X2Apic mode.Number of Coresper ProcessorControls the number of enabled cores in each processor. By default, the Numberof Cores per Processor option is set to All.HardwarePrefetcherEnables or disables the hardware prefetcher. By default, the Hardware Prefetcheroption is set to Enabled.DCU StreamerPrefetcherAllows you to enable or disable the Data Cache Unit (DCU) streamer prefetcher. Bydefault, 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 DCUIP 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.32
