Option Description
Hardware
Prefetcher
Enables or disables the hardware prefetcher. This option is set to Enabled by default.
Software
Prefetcher
Enables or disables the software 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.
UPI Prefetch Enables you to get the memory read started early on DDR bus. The Ultra Path Interconnect (UPI) Rx path will
spawn the speculative memory read to Integrated Memory Controller (iMC) directly. This option is set to Enabled
by default.
Logical Processor
Idling
Enables you to improve the energy eciency 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.
Congurable TDP Enables you to congure the TDP level. The available options are Nominal, Level 1, and Level 2. This option is set
to Nominal by default.
NOTE: This option is only available on certain stock keeping units (SKUs) of the processors.
SST-Performance
Prole
Enables you to recongure the processor using Speed Select Technology.
x2APIC Mode Enables or disables the x2APIC 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 congure the Dell AVX scaling technology. This option is set to 0 by default.
Number of Cores
per Processor
Controls the number of enabled cores in each processor. This option is set to All by default.
Processor Core
Speed
Species the maximum core frequency of the processor.
