Memory configurations
To optimize server availability, the server supports Advanced ECC AMP mode:
• Advanced ECC — Provides up to 4-bit error correction. This mode is the default option for this server.
Advanced Memory Protection options are configured in the BIOS/Platform Configuration (RBSU). If the
requested AMP mode is not supported by the installed DIMM configuration, the server boots in Advanced
ECC mode. For more information, see the
HPE UEFI System Utilities User Guide
for HPE ProLiant Gen9
Servers on the
Hewlett Packard Enterprise website
.
Advanced ECC memory configuration
Advanced ECC memory is the default memory protection mode for this server. Standard ECC can correct
single-bit memory errors and detect multi-bit memory errors. When multi-bit errors are detected using
Standard ECC, the error is signaled to the server and causes the server to halt.
Advanced ECC protects the server against some multi-bit memory errors. Advanced ECC can correct both
single-bit memory errors and 4-bit memory errors if all failed bits are on the same DRAM device on the DIMM.
Advanced ECC provides additional protection over Standard ECC because it is possible to correct certain
memory errors that would otherwise be uncorrected and result in a server failure. Using HPE Advanced
Memory Error Detection technology, the server provides notification when a DIMM is degrading and has a
higher probability of uncorrectable memory error.
General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
• Install DIMMs that are optimized for the installed processor.
• To identify the processor type installed in the server, use the BIOS/Platform Configuration (RBSU) of the
UEFI System Utilities.
• Do not mix LRDIMMs and RDIMMs.
• White DIMM slots denote the first slot of a channel (Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D).
• When only one processor is installed, install DIMMs in sequential alphabetic order: A, B, C, D, E, F, and so
forth.
• When two processors are installed, install the DIMMs in sequential alphabetical order balanced between
the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth.
• DIMMs should be populated starting farthest from the processor on each channel.

Identifying the processor type
The processor type installed in the server is briefly displayed during POST. To view this information and
additional processor specifications, do the following:
Procedure
1.
Reboot the server.
The server restarts and the POST screen appears.
2.
Press
F9
.
The System Utilities screen appears.
3.
Select
System Information
|
Processor Information
.
The Processor Information screen shows detailed information about the processors installed in the server.
4.
Press
Esc
until the main menu is displayed.
5.
Select
Reboot the System
to exit the utility and resume the boot process.
