Description
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.
Enables you to configure the Dell AVX scaling technology. This
option is set to 0 by default. Enter the value from 0 to 12
bins. The value that is entered decreases the Dell AVX Scaling
Technology frequency when the Dell-controlled Turbo feature is
enabled.
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.
This option enables one of the Mid-Level Cache (MLC) AMP
hardware Prefetcher. This option is set to Disabled by default.
This option allows L1 Data Cache Unit (DCU) to prefetech, when
the Fill Buffers (FB) is full. Auto maps to hardware default
setting. This option is set to Auto by default.
This setting controls whether the Running Average Power Limit
(RAPL) balancer is enabled or not. If enabled, it activates the
uncore power budgeting. This option is set to Enabled by
default.
Specifies the maximum core frequency of the processor.
Specifies the bus speed of the processor.
NOTE:
The processor bus speed option displays only when
both processors are installed.
Enables or disables the local machine check exception. This
is an extension of the MCA Recovery mechanism providing
the capability to deliver Uncorrected Recoverable (UCR)
Software Recoverable Action Required (SRAR) errors to one
or more specific logical processors threads receiving previously
poisoned or corrupted data. When enabled, the UCR SRAR
Machine Check Exception is delivered only to the affected
thread rather than broadcast to all threads in the system.
