DIMM identification

IMPORTANT:
these two types causes the server to halt during BIOS initialization.
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.
This server does not support mixing RDIMMs and UDIMMs. Attempting to mix
