8.2.1 Memory mounting rules
Install the memory in accordance with the following rules:
Mount memory in units of eight modules.
Within a unit of eight modules, all the memory modules must be of the same
capacity and rank.
For memory for one CPU, use only R-DIMM (Registered DIMM: 8 GB/16 GB/32
GB) or only LR-DIMM (Load Reduced DIMM: 64 GB).
First mount memory group A and then mount memory group B.
Figure 8-3 shows the mounting locations of all the memory modules. Each
eight-module unit of mounted memory is indicated by letters a to f. Table 8-1, Table
8-2 and Table 8-3 list the supported memory installation configurations. The memory
mounting locations may vary depending on the number of mounted CPU memory
units. Refer to this figure and table when you expand or reduce memory.
As for the mounting order of memory group B, give priority to using a uniform
memory type of either R-DIMM or LR-DIMM for one CPU over the memory
mounting patterns in Table 8-1, Table 8-2,andTable 8-3.
