	Spare with Advanced ECC 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.
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, and Cluster on Die. By default, the Snoop
	Mode option is set to Early Snoop. The field is only available when Node
	Interleaving is Disabled.

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 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

	Translation and Protection Table to translate DMA addresses to host
	addresses. By default, the option is set to Enabled.
Adjacent Cache Line	Optimizes the system for applications that require high utilization of
Prefetch	sequential memory access. By default, the Adjacent Cache Line Prefetch
