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. The options available are
Optimizer Mode, Advanced ECC Mode, Mirror Mode, Spare Mode,
Spare with Advanced ECC Mode, and Dell Fault Resilient Mode. By
default, the Memory Operating Mode option is set to 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.
Node Interleaving If this field is Enabled, memory interleaving is supported if a symmetric
memory configuration is installed. If Disabled, the system supports Non-
Uniform Memory architecture (NUMA) (asymmetric) memory
configurations. By default, Node Interleaving option is set to Disabled.
Snoop Mode Snoop Mode options available are Disabled, Home Snoop, Early Snoop,
Cluster on Die. By default, the Snoop Mode option is set to Disabled. The
field is only available when Node Interleaving is Disabled.
Processor Settings screen
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.
To view the Processor Settings screen click the System Setup Main Menu → System BIOS → Processor
Settings.
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 displays only one logical processor per core. By default, the
Logical Processor option is set to Enabled.
Alternate RTID (Requestor
Transaction ID) Setting
Enables you to allocate more RTIDs to the remote socket, thereby
increasing cache performance between the sockets or easing work in
normal mode for NUMA. By default, the Alternate RTID (Requestor
Transaction ID) Setting is set to Disabled.
Virtualization Technology Enables or disables the additional hardware capabilities provided for
virtualization. By default, the Virtualization Technology option is set to
Enabled.
Address Translation Service
(ATS)
Defines the Address Translation Cache (ATC) for devices to cache the
DMA transactions. This field provides an interface to a chipset's Address
Translation and Protection Table to translate DMA addresses to host
addresses. By default, the 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
