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.
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.

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.
Logical Processor Idling 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.
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.
