Placement rules for memory in the 8348-21C system

Learn about the configurations and rules that apply to adding memory to the IBM® Power® System S812LC (8348-21C) system.

Table 1 lists the supported memory DIMM feature codes and Table 2 shows the allowable memory capacity points for the 8348-21C system. Mixing of memory feature codes is not allowed.

Table 1. Memory DIMM feature codes
Supported feature codes (FC) Size
EM5A 4 GB IS DIMMS, 1333 MHZ, 4 GBIT DDR3 DRAM
EM5C 16 GB IS DIMMS, 1333 MHZ, 16 GBIT DDR3 DRAM
EM5D 32 GB IS DIMMS, 1333 MHZ, 32 GBIT DDR3 DRAM
EM5E 8 GB IS DIMMS, 1066 MHZ, 8 GBIT DDR3 DRAM
Table 2. 8348-21C memory configuration as a function of the number of DIMMs. You read this table by selecting the individual DIMM size row in the leftmost column, then move to the right and select the columns for the memory capacity. The value that is listed is the quantity of the memory feature code that can be ordered, which corresponds to the DIMM size in the leftmost column.
  32 GB 64 GB 128 GB 256 GB 512 GB 1024 GB
DIMM Size DIMMs DIMMs DIMMs DIMMs DIMMs DIMMs
4 GB 81 16 32      
8 GB     161 32    
16 GB       161 32  
32 GB         161 32
Notes:
  1. Default configurations for the listed memory capacity
Use Table 3 and Figure 1 to determine the memory placement. The memory needs to be plugged in a sequence: Slots with blue connectors are plugged first. Slots with ivory connectors are plugged second. Slots with black connectors are plugged last.
Table 3. Memory plugging sequence
Slot latch color Slot number Sequence
Blue 22, 24, 30, 32, 38, 40, 46, 48 Fill these DIMM slots first
Ivory 26, 28, 34, 36, 42, 44, 50, 52 Fill these DIMM slots second
Black 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53 Fill these DIMM slots last
