This server supports 2GB to 512GB of system memory using DDR3 2GB, 4GB, 8GB, 16GB and 32GB 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.

Online Spare memory
Online Spare memory mode is a higher level of memory protection that complements Standard Memory mode with Advanced
ECC. With Online Spare mode, a DIMM with a rank of memory at least as large as the other ranks in the system, or memory
board, is designated as the Online Spare rank.2 If one of the other DIMMs exceeds a threshold rate of correctable memory
errors, the affected rank of memory within that DIMM is taken offline and the data is copied to the Online Spare rank. This
capability maintains server availability and memory reliability without service intervention or server interruption. The DIMM that
exceeded the error threshold can be replaced at the customer's convenience during a scheduled shutdown. Online Spare
reduces the chance of an uncorrectable error bringing down the system; however, it does not fully protect the system against
uncorrectable memory errors.
Online Spare mode is beneficial to businesses with sites that do not have IT staff available to service a failure, do not always
have replacement memory readily available, or cannot bring down the server until a scheduled shutdown. The cost of
implementation for Online Spare over Advanced ECC is the hardware cost of the extra DIMMs for the spare memory bank.
The user configures the system for Online Spare mode through the RBSU3. Online Spare configuration requirements vary for
each server series, but it does not require operating system support or special software beyond the System BIOS. However, if
messaging and logging are desired at the console along with messages in HP Systems Insight Manager, an operating system
must be used that has system management and agent support for Advanced Memory Protection.

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.
