Option
Description
Logical Processor
Enables or disables the logical processors and displays the number of logical processors. If this option is set to
Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS displays only one
logical processor per core. This option is set to Enabled by default.
Virtualization
Technology
Enables or disables the virtualization technology for the processor. This option is set to Enabled by default.
Adjacent Cache
Line Prefetch
Optimizes the system for applications that need high utilization of sequential memory access. This option is set to
Enabled by default. You can disable this option for applications that need high utilization of random memory
access.
Hardware
Prefetcher
Enables or disables the hardware prefetcher. This option is set to Enabled by default.
Logical Processor
Idling
Enables you to improve the energy eciency of a system. It uses the operating system core parking algorithm and
parks some of the logical processors in the system which in turn allows the corresponding processor cores to
transition into a lower power idle state. This option can only be enabled if the operating system supports it. It is set
to Disabled by default.
x2APIC Mode Enables or disables the x2APIC mode. This option is set to Disabled by default.
Number of Cores
per Processor
Controls the number of enabled cores in each processor. This option is set to All by default.
Processor Core
