Memory Sparing Support
Memory sparing is supported in single- or dual-processor systems that have one of the fully populated
memory configurations shown in Table 3-1. The memory sparing feature must be enabled in the Memory
Information screen of the System Setup program. See "Using the System Setup Program" on page 37. To
use memory sparing, you must disable node interleaving.
Memory sparing is applied independently to the two groups of DIMMs on opposite sides of the processor
sockets. To support memory sparing, all DIMM sockets within a DIMM group must be populated.
