Dual- and quad-rank DIMMs provide the greatest capacity with the existing memory technology. For

example, if current DRAM technology supports 2-GB single-rank DIMMs, a dual-rank DIMM would be 4-GB,

and a quad-rank DIMM would be 8-GB.

DIMM identification

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

Voltage rating L = Low voltage (1.35v)

Blank or omitted = Standard

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.
