Table 25. Processor Settings details (continued)
Option Description
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.
DCU Streamer Prefetcher Enables or disables the Data Cache Unit (DCU) streamer
prefetcher. This option is set to Enabled by default.
DCU IP Prefetcher Enables or disables the Data Cache Unit (DCU) IP prefetcher.
This option is set to Enabled by default.
System Isochronous Mode This feature reduces latency of memory transactions at the
expense of bandwidth. Enabling it may be best for real-time
audio and video streaming applications. Disabling it may be
best for applications needing highest memory bandwidth
especially with large number of cores under heavy utilization.
This option is set to Disabled by default.
Sub NUMA Cluster Enables or disables the Sub NUMA Cluster. This option is set
to Disabled by default.
MADT Core Enumeration Specifies the MADT Core Enumeration. This option is set
to default in Round Robin. Linear option supports industry
core enumeration whereas, Round Robin option supports Dell
optimized core enumeration.
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 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.
Dynamic SST-Performance Profile Enables you to reconfigure the processor using Dynamic
or Static Speed Select Technology. This option is set to
Disabled by default.
SST-Performance Profile Enables you to reconfigure the processor using Speed Select
Technology.
Intel SST-BF Enables Intel SST-BF. This option is displayed if Performance
Per Watt (operating system) or Custom (when OSPM is
36 Pre-operating system management applications
