Rank 1, 2: DIMM1_A and DIMM1_B

Rank 3, 4: DIMM2_A and DIMM2_B

Rank 5, 6: DIMM3_A and DIMM3_B

The memory modules must be installed in identical pairs in configurations
that have more than one memory module. For example, if socket DIMM1_A
contains a 512-MB memory module, then the second memory module to be
installed must be a 512-MB memory module in socket DIMM1_B.

Table 3-1 shows examples of different memory configurations, based on the
following guidelines:

•

The minimum memory configuration is 512 MB.

•

If only one memory module is installed, it must be installed in the
DIMM1_A socket.

•

A rank must contain identical memory modules.

•

Install memory modules in rank 1, 2(DIMM1_

x) before installing memory

modules in rank 3, 4 (DIMM2_

x), and install memory modules in rank 3, 4

before installing rank 5, 6 (DIMM3_

x).

•

Configurations of three or five memory modules are not supported.
