Using the System Setup Program 39CPU Information ScreensTable 2-3 lists the options and descriptions for the information fields that appear on the CPUInformation screen.Table 2-3. CPU Information ScreenOption Description64-bit Technology Specifies if the installed processor(s) support Intel 64-bitextensions.Core Speed Displays the clock speed of the processor(s).Bus Speed Displays the bus speed of the processor(s).Logical Processor(Enabled default)Displays when the processors support HyperThreading. Enabledpermits all logical processors to be used by the operating system.Only the first logical processor of each processor installed in thesystem is used by the operating system if Disabled is selected.Virtualization Technology(Disabled default)Displays when the processor(s) support Virtualization Technology.Enabled permits virtualization software to use VirtualizationTechnology incorporated in the processor design. This feature canonly be used by software that supports Virtualization Technology.Adjacent Cache LinePrefetch(Enabled default)Enables or disables optimal use of sequential memory access.Disable this option for applications that require high use of randommemory access.Hardware Prefetcher(Enabled default)Enables or disables the hardware prefetcher.Demand-Based PowerManagement(Disabled default)Enables or disables demand-based power management. Whenenabled, the CPU Performance State tables will be reported to theoperating system; when disabled, the CPU Performance Statetables will not be reported to the operating system. If any of theCPUs do not support demand-based power management, the fieldwill become read-only, and automatically set to Disabled.Processor X ID Displays the family and model number of each processor. Asubmenu displays processor core speed, amount of level 2 cache,and number of cores.
