Memory configurations
This server supports 2 GB to 256 GB of system memory using DDR3 2-GB, 4-GB, 8-GB, and 16-GB memory
modules across 24 memory sockets.
Advanced ECC memory
Advanced ECC memory is the memory protection mode for this server. In Advanced ECC, the server does not
fail because of correctable memory errors. The server provides notification if the level of correctable errors
exceeds a pre-defined threshold rate.
Advanced ECC provides additional protection over standard ECC because it is possible to correct certain
memory errors that would otherwise be uncorrectable and result in a server failure.
Whereas standard ECC can correct single-bit memory errors, Advanced ECC can correct single-bit memory
errors and multi-bit memory errors if all failed bits are on the same DRAM device on the memory module.
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:
