Processor Settings Screen Details - Dell Precision 7920 Rack Owner's Manual

Menu Item Description
Current State of Specifies current state of memory operating mode. Option is Optimizer.
Memory Operating
Mode
Node Interleaving Specifies if Non-Uniform Memory architecture (NUMA) is supported. If this field is Enabled, memory interleaving is
supported if a symmetric memory configuration is installed. If Disabled, the system supports NUMA (asymmetric)
memory configurations. By default, Node Interleaving option is set to Disabled.

Processor settings screen details

You can use the Processor Settings screen to view the processor settings and perform specific functions such as enabling virtualization
technology, hardware prefetcher, and logical processor idling.
You can view the Processor Settings screen by clicking System Setup Main Menu > System BIOS > Processor Settings.
The Processor Settings screen details are explained as follows:
Menu Item Description
Logical Processor Enables or disables the logical processors and displays the number of logical processors. If the Logical Processor
option is set to Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS only
displays one logical processor per core. By default, the Logical Processor option is set to Enabled.
Virtualization Enables or disables the additional hardware capabilities provided for virtualization. By default, the Virtualization
Technology Technology option is set to Enabled.
Adjacent Cache Optimizes the system for applications that require high utilization of sequential memory access. By default, the
Line Prefetch Adjacent Cache Line Prefetch option is set to Enabled. You can disable this option for applications that require
high utilization of random memory access.
Hardware Enables or disables the hardware prefetcher. By default, the Hardware Prefetcher option is set to Enabled.
Prefetcher
DCU Streamer Allows you to enable or disable the Data Cache Unit (DCU) streamer prefetcher. By default, the DCU Streamer
Prefetcher Prefetcher option is set to Enabled.
DCU IP Prefetcher Enables or disables the Data Cache Unit (DCU) IP prefetcher. By default, the DCU IP Prefetcher option is set to
Enabled.
Sub NUMA Cluster Enables or disables the execute disable memory protection technology. By default, the Execute Disable option is
set to Enabled.
Logical Processor Enables or disables the breaking up the LLC into disjoint clusters based on address range with each cluster bound
Idling to a subset the memory controllers. Option is set to Disabled.
Configurable TDP Allows reconfiguration of Thermal Design Power (TDP) to lower levels.
TDP refers to the maximum amount of power the cooling system is required to dissipate.
The options are Normal (set by default), Level 1 and Level 2
X2Apic Mode Enables or disables the X2Apic mode.
Dell Controlled
Turbo
Controls the turbo engagement. Enable this option only when System Profile is set to Performance.
Number of Cores Controls the number of enabled cores in each processor. By default, the Number of Cores per Processor option is
per Processor set to All.

NOTE: The Memory Operating Mode can have different defaults and available options based on the
memory configuration of your system.
NOTE: The Dell Fault Resilient Mode establishes an area of memory that is fault resilient. This mode
can be used by an operating system that supports the feature to load critical applications or enables the
operating system kernel to maximize system availability.
NOTE: Depending on the number of installed CPUs, there may be up to four processor listings.
