Description
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.
Enables or disables the virtualization technology for the processor. This option is set to
Enabled by default.
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.
Enables or disables the hardware prefetcher. This option is set to Enabled by default.
Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to
Enabled by default.
Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled
by default.
Enables or disables the Sub NUMA Cluster. This option is set to Enabled by default.
Enables you to improve the energy efficiency 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.
Enables you to reconfigure the processor Thermal Design Power (TDP) levels during POST
based on the power and thermal delivery capabilities of the system. TDP verifies the
maximum heat the cooling system is needed to dissipate. This option is set to Nominal by
default.
NOTE: This option is only available on certain stock keeping units (SKUs) of the
processors.
Enables or disables the X2Apic mode.
Controls the turbo engagement. Enable this option only when System Profile is set to
Performance.
NOTE: Depending on the number of installed CPUs, there may be up to four
processor listings.
Displays the X2Apic Mode setting that is read only and permanently set to enabled.
Controls the number of enabled cores in each processor. This option is set to All by default.
Specifies the maximum core frequency of the processor.
