Table 13. Processor Settings details(continued)
Option Description
UMA Based Clustering This field is read-only and shows as Quadrant when the Sub NUMA Cluster is disabled, or
displays as Disabled, when Sub NUMA Cluster is either 2-way or 4-way.
UPI Prefetch Enables you to get the memory read started early on DDR bus. The Ultra Path Interconnect
(UPI) Rx path spawns the speculative memory that is read to Integrated Memory
Controller (iMC) directly. This option is set to Enabled by default.
XPT Prefetch This option is set to Enabled by default.
LLC Prefetch Enables or disables the LLC Prefetch on all threads. This option is set to Enabled by
default.
Dead Line LLC Alloc 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.
Directory AtoS 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.
AVX P1 Enables you to reconfigure the processor TDP levels during POST based on the power and
thermal delivery capabilities of the system. TDP verifies the maximum heat that the cooling
system must dissipate. This option is set to Normal by default.
NOTE: This option is only available on certain processor SKUs.
Intel SST-BF Enables Intel SST-BF. This option is displayed if Performance Per Watt (operating system)
or Custom (when OSPM is enabled) system profiles are selected. This option is set to
Disabled by default.
Intel SST-CP Enables Intel SST-CP. This option displays 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.
NOTE: This option is hidden if the processor installed does not support SST
capabilities.
x2APIC Mode Enables or disables x2APIC mode. This option is set to Enabled by default.
NOTE: For two processors with a 64 core configuration, x2APIC mode is not
switchable if 256 threads are enabled (BIOS settings: All CCD, cores, and logical
processors are enabled).
AVX ICCP Pre-Grant
License
Enables or disables AVX ICCP Pre-Grant License. This option is set to Disabled by default.
Table 14. Dell Controlled Turbo
Option Description
Dell Controlled Turbo
Settings
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.
Dell AVX Scaling
Technology
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. When the Dell-controlled Turbo feature is enabled, the
value that is entered decreases the Dell AVX Scaling Technology frequency.
Optimizer Mode Enables or disables the CPU performance. When this option is set to Auto, set the CPU
Power Management to Max Performance. When set to Enabled, enables the CPU Power
Management settings. When set to Disabled, the CPU Power Management option is
disabled. This option is set to Auto by default.
