Memory Configurations - HP ProLiant DL G6 User Manual

The memory subsystem may be populated with either RDIMMs or UDIMMs, but mixing the two types is not
supported. To determine DIMM characteristics, use the label attached to the DIMM and the following
illustration and table.

Memory configurations

To optimize server availability, the server supports the following AMP modes:
•
Advanced ECC—provides the greatest memory capacity for a given DIMM size, while providing up to
4-bit error correction. This mode is the default option for this server.
•
Mirrored Memory—provides maximum protection against failed DIMMs. Uncorrectable errors in one
channel are corrected by the mirror channel.
•
Lockstep—provides enhanced protection while making all installed memory available to the operating
system. The server can continue to function if a single- or multi-bit memory failure within a single DRAM
device occurs.
Advanced Memory Protection options are configured in 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
"HP ROM-Based Setup Utility (on page 116)."
