Menu Item Description
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 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.
Snoop Mode Specifies the Snoop Mode options. Snoop Mode options available are Home
Snoop, Early Snoop, Cluster on Die. By default, the Snoop Mode option is set to
Early Snoop. The field is only available when Node Interleaving is 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

Maximum data
rate
QPI Speed maximum data rate 9.6 Gt/s, 8.0 GT/s, 6.4 GT/s
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
Services (ATS)
Allows you to define the Address Translation Cache (ATC) for devices to cache the
DMA transactions. This filed provides an interfaces 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 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
