This server supports 2GB to 256GB of system memory using DDR3 2GB, 4GB, 8GB, and 16GB memory modules across 24
memory sockets.
For detailed memory configuration rules and guidelines, please use the Online DDR3 Memory Configuration Tool:

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
Population orderPopulation order
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.

Population rules
When installing memory modules, observe the following population rules:
Use only HP memory modules listed in this document.
Advanced ECC is not available if x4 and x8 memory modules are mixed in channels (A and B), (C and D), or both, but
standard ECC is still available. Advanced ECC is available if x4 and x8 memory modules are mixed in memory channels (A
and C), (B and D), or both.
No more than two UDIMMs may be installed per channel.
Do not mix UDIMMs and RDIMMs within this server.
