Description
Enables or disables the Dead Line LLC Alloc. This option is set
to Enabled by default. You can enable this option to enter the
dead lines in LLC or disable the option to not enter the dead
lines in LLC.
Enables or disables the Directory AtoS. AtoS optimization
reduces remote read latencies for repeat read accesses
without intervening writes. This option is set to Disabled 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.
NOTE:
This feature is not supported if CPU Power
Management is set to Maximum Performance.
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 must dissipate. This
option is set to Normal by default.
NOTE:
This option is only available on certain stock
keeping units (SKUs) of the processors.
Enables Intel SST-CP. This option is displayed if Performance
Per Watt (operating system) or Custom (when OSPM is
enabled) system profiles are selected. This option is displayed
and selectable for each system profile mode. This option is set
to Disabled by default.
Enables or disables x2APIC mode. This option is set to
Enabled by default.
NOTE:
For two processors 64 cores configuration,
x2APIC mode is not switchable if 256 threads are enabled
(BIOS settings: All CCD, cores, and logical processors
enabled).
Enables or disables AVX ICCP Pre-Grant License. This option
is set to Disabled by default.
Controls the turbo engagement. Enable this option only when
System Profile is set to Performance or Custom, and CPU
Power Management is set to Performance. This item can be
selected for each system profile mode. This option is set to
Disabled by default.
NOTE:
Depending on the number of installed processors,
there might be up to two processor listings.
Controls the number of enabled cores in each processor. This
option is set to All by default.
Limit CPU physical address to 46 bits to support older Hyper-
V. If enabled, automatically disables TME-MT. This option is
set to Enabled by default.
Specifies the maximum core frequency of the processor.
