3.1.3.3 DIMM Population Rules and Supported DIMM Configurations
DIMM population rules depend on the operating mode of the memory controller, which is
determined by the number of DIMMs installed.
DIMMs must be populated in pairs. DIMM pairs
are populated in the following DIMM slot order: A1 & B1, C1 & D1, A2 & B2, C2 & D2. DIMMs
within a given pair must be identical with respect to size, speed, and organization. However,
DIMM capacities can be different between different DIMM pairs.
For example, a valid mixed DIMM configuration may have 512MB DIMMs installed in DIMM
Slots A1 & B1, and 1GB DIMMs installed in DIMM slots C1 & D1.
Intel supported DIMM configurations for this server board are shown in the following table.
Supported and Validated configuration : Slot is populated
Supported but not validated configuration : Slot is
populated
Slot is not populated
Mirroring: Y = Yes. Indicates that configuration supports Memory Mirroring.
Sparing: Y(x) = Yes. Indicates that configuration supports Memory Sparing.
Where x
= 0 : Sparing supported on Branch0 only
1 : Sparing supported on Branch1 only
0,1 : Sparing supported on both branches
