Menu Item Description
System Memory
Testing
Specifies whether system memory tests are run during system boot. Options are Enabled and Disabled.
By default, the System Memory Testing option is set to Disabled.
Memory
Operating Mode
Specifies the memory operating mode. By default Optimizer Mode.
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.
Current State
of Memory
Operating Mode
Specifies current state of memory operating mode. Option is Optimizer.
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.
About this task
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
Technology
Enables or disables the additional hardware capabilities provided for virtualization. By default, the
Virtualization Technology option is set to Enabled.
Adjacent Cache
Line Prefetch
Optimizes the system for applications that require high utilization of sequential memory access. By
default, the 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
Prefetcher
Enables or disables the hardware prefetcher. By default, the Hardware Prefetcher option is set to
Enabled.
DCU Streamer
Prefetcher
Allows you to enable or disable the Data Cache Unit (DCU) streamer prefetcher. By default, the DCU
Streamer 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
Idling
Enables or disables the breaking up the LLC into disjoint clusters based on address range with each
cluster bound 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.
