36 IBM Power System S822 Technical Overview and Introduction
2.2.2 Memory placement rules
The following memory options are orderable:
򐂰 16 GB CDIMM, 1600 MHz DDR3 DRAM (#EM83)
򐂰 32 GB CDIMM, 1600 MHz DDR3 DRAM (#EM84)
򐂰 64 GB CDIMM, 1600 MHz DDR3 DRAM (#EM85)
All memory must be ordered in pairs with a minimum of 32 GB memory required for a
Power S822 system.
The supported maximum memory is as follows:
򐂰 One processor module installed: 512 GB (eight 64 GB CDIMMs)
򐂰 Two processor modules installed: 1024 GB (sixteen 64 GB CDIMMs)
The basic rules for memory placement follows:
򐂰 Each feature code equates to a single physical CDIMM.
򐂰 All memory features must be ordered in pairs.
򐂰 All memory CDIMMs must be installed in pairs.
򐂰 Each CDIMM within a pair must be of the same capacity.
Figure 2-10 on page 37 shows the physical memory DIMM topology.
