Option Description
Adjacent Cache Line Prefetch Optimizes the system for applications that need high utilization of sequential memory
access. This option is set to Enabled by default. You can disable this option for 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 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 recongure the processor Thermal Design Power (TDP) levels during POST
based on the power and thermal delivery capabilities of the system. TDP veries the
maximum heat the cooling system is needed to dissipate. This option is set to Nominal by
default.
NOTE: This option is only available on certain stock keeping units (SKUs) of the
processors.
X2Apic Mode Enables or disables the X2Apic mode.
Dell Controlled Turbo Controls the turbo engagement. Enable this option only when System Prole is set to
Performance.
NOTE: Depending on the number of installed CPUs, there may be up to four
processor listings.
X2Apic Mode Displays the X2Apic Mode setting that is read only and permanently set to enabled.
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.
Processor 1
NOTE: Depending on the number of CPUs, there may be up to four processors
listed.
The following settings are displayed for each processor installed in the system:
• Family-Model-Stepping: Species the family, model, and stepping of the processor as
dened by Intel.
• Brand: Species the brand name.
• Level 2 Cache: Species the total L2 cache.
• Level 3 Cache: Species the total L3 cache.
• Number of Cores: Species the number of cores per processor.
