Supported FB-DIMM Configurations

Use these FB-DIMM configuration rules to help you plan the memory configuration
of your server:
Up to 16 FB-DIMMs can be installed in each CMP/memory module pair.
■
Each bank consists of four FB-DIMMs.
■
Each bank must be populated completely, never partially.
■
For each CPU/Memory module pair, all FB-DIMMs must be of the same capacity,
■
either 2 GB, 4 GB or 8 GB per FB-DIMM.
Memory bank 0 must always be populated.
■
Memory bank 1 must be populated before banks 2 and 3.
■
Memory banks 2 and 3 must be populated simultaneously and completely.
■
The number of FB-DIMMs installed on a processor and its associated memory
■
expansion module must be either 4, 8 or 16. No other combinations are
supported.
4 GB FB-DIMMs at 800 Mhz are available for 1.6-Ghz systems only and cannot be
■
mixed with other FB-DIMMs of different speed within the same system.
