3.3.2.1 DIMM Population Rules
DIMM population rules depend on the operating mode of the memory controller, which is determined
by the number of DIMMs installed. DIMM pairs are populated in the following DIMM slot order: A1 and
B1, A2 and B2, A3 and B3.
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 512 Mbyte DIMMs installed in DIMM slots A1 and B1, and 1 Gbyte DIMMs
installed in DIMM slots A2 and B2. Single DIMM operation is supported with the DIMM populated in
slot A1 only, but populating in pairs is recommended.
