Memory Sparing Support - PowerEdge M605

Memory sparing is supported in single- or dual-processor systems that have one

of the fully populated memory configurations shown in Table 3-9.

The memory

sparing feature must be enabled in the Memory Information screen of the

System Setup program. See "Memory Information Screen" on page 83. To use

memory sparing, you must disable node interleaving.

Memory sparing allocates only the first rank of memory of a DIMM. For a

single-rank DIMM, the entire capacity of the DIMM must be allocated for

sparing along with the adjacent single-rank DIMM to spare a memory

channel. For dual-rank DIMMs, two DIMMs are also required for sparing, but

as only the first rank of each DIMM is allocated, only half of a dual-rank

DIMM’s capacity is allocated for sparing. The second ranks on both DIMMs

are available memory. Table 3-9 shows how memory sparing splits the

available and spared memory in each memory module configuration.
