Configuring and Installing Components 5-23

5.10

Memory Configuration

Become familiar with the rules for memory configuration before

adding DIMMs to the system.

Refer to Figure 5–11 or Figure 5–12 and observe the following rules for

installing DIMMs.

•

You can install up to 16 DIMMs or up to 32 DIMMs, depending on the

system model you purchased.

•

A set consists of 4 DIMMs. You must install all 4 DIMMs.

•

Fill sets in numerical order. Populate all 4 slots in Set 0, then populate Set

1, and so on.

•

An “array” is one set for systems that support 16 DIMMs and two sets for

systems that support 32 DIMMs.

•

DIMMs in an array must be the same size and type. For example, suppose

you have populated Sets 0, 1, 2, and 3. When you populate Set 4, the

DIMMs must be the same size and type as those installed in Set 0.

Similarly, Set 5 must be populated with the same size and type of DIMMs

as are in Set 1, and so on, as indicated in the following table.
