DIMM identification

IMPORTANT: This server does not support mixing RDIMMs and UDIMMs. Attempting to mix

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.

Item Description Definition

Size —

Rank

1R = Single-rank

2R = Dual-rank

4R = Quad-rank

Data width x4 = 4-bit

x8 = 8-bit

Memory speed 10600 = 1333-MHz

8500 = 1066-MHz

DIMM type R = RDIMM (registered)

E = UDIMM (unbuffered with ECC)

For the latest supported memory information, see the QuickSpecs on the HP website (http://www.hp.com).

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.
