Dell R805 owner manual CPU Information Screen

Table 2-3. Memory Information Screen (continued)

Option	Description
Redundant Memory	Enables or disables the redundant memory feature.
(Disabled default)	When set to Spare Mode, the first rank of memory on
	each DIMM is reserved for memory sparing. See
	"Memory Sparing Support" on page 116. Redundant
	memory feature is disabled if the Node Interleaving field
	is enabled.
Node Interleaving	If this field is enabled, memory interleaving is supported
	if a symmetric memory configuration is installed. If this
	field is set to disabled (the default), the system can
	support Non-Uniform Memory architecture (NUMA)
	(asymmetric) memory configurations.
	NOTE: The Node Interleaving field must be set to Disabled
	when using the redundant memory feature.
Memory Optimizer	Sets the behavior of the two DRAM controllers for
Technology	memory optimization. When set to Enabled, the two
(Enabled default)	controllers run in parallel 64-bit mode for improved
	memory performance (running single-bit ECC).When
	set to Disabled, the controllers are joined in 128-bit
	mode running multi-bit Advanced ECC.
Low Power Mode	Enables or disables the low power mode of the memory.
(Disabled default)	When set to Disabled, the memory runs at full speed.
	When set to Enabled, the memory runs at a reduced
	speed to conserve energy.
