Placement rules for memory in the 9006-12P or 9006-22P system

Learn about the configurations and rules that apply to adding memory to the IBM Power System LC921
(9006-12P) or IBM Power System LC922 (9006-22P) system.
• The system supports, 2, 4, 6, 8, 12, or 16 memory DIMMs (dual inline memory modules)
• The memory DIMMs can be 8, 16, 32, 64, or 128 GB
• For a single-processor system, the first four DIMMs must be installed in a pairs. After the first four
DIMMs, you must add memory DIMMs in quads.
• For a two-processor system, the first eight DIMMs must be installed in a pairs. After the first eight
DIMMS, you must add memory DIMMs in quads.
• Memory pairs must have the same size and type (A and B must match each other; C and D must match
each other).
• Memory pairs can have different memory sizes and types from other memory pairs (A and B do not need
to match C and D).
• The memory DIMMs must be added in a sequence.
• For a two-processor system, use Table 4 on page 26 and Figure 21 on page 27 to determine the
memory placement.
• For a single-processor system, use Table 5 on page 27 and Figure 22 on page 28.
