Memory configurations
This server supports up to 1 TB of system memory using DDR3 2-GB, 4-GB, 8-GB, 16-GB, and 32-GB memory
modules across 48 memory sockets.
Population order
The two tables below represent the memory module population order for one processor. The population
order for the other processor is identical. SR denotes Single Rank, DR denotes Dual Rank, and QR denotes
Quad Rank.
All memory modules must follow the population order shown in these two tables for both processors with the
following exception:
• QR memory modules must be installed only in memory sockets 2, 5, 8, and 11, while following the
population order for those memory sockets.
