6.5.2.2 DIMM Mounting Conditions
■ Memory modules are added in sets of 16 DIMMs.
■ The DIMMs mounted in the MEM#xxA slot are defined as Group A. The DIMMs
mounted in the MEM#xxB slot are defined as Group B. The standard memory modules
are included in Group A.
■ The memory size of Group A is equal to or greater than that of Group B.
■ Group B need not always include memory modules.
■ Mount memory modules of the same size and rank in each group. Memory modules of
different sizes or ranks cannot be mounted in a single group.
Note – When you upgrade using larger capacity memory than the capacity of
Group-A, move the memory mounted in Group-A to Group-B, and then mount the
upgrade memory to Group-A.
