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

option is set to Enabled.
Enables or disables the additional hardware capabilities provided for virtualization. By default, the
Virtualization
Virtualization Technology option is set to Enabled.
Technology
Optimizes the system for applications that require high utilization of sequential memory access. By
Adjacent Cache
default, the Adjacent Cache Line Prefetch option is set to Enabled. You can disable this option for

The Memory Operating Mode can have different defaults and available options based on
NOTE:
the memory configuration of your system.
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.
