Types of Memory Configurations

2.4.2 Types of Memory Configurations

Interleaved configurations require matched pairs of memory-module kits

(the size and the speed must be the same).

The kits must be installed

in the following order:

pair J1 & J3 (Model 90)

or A1 & B1 (Model

95), then pair J2 & J4 (Model 90) or A2 & B2 (Model 95), and so forth.

This technique of addressing memory in pairs enhances performance.

Noninterleaved configurations do not require matched pairs of

memory-module kits (the size and speed does not have to be the same).

Noninterleaved memory runs less efficiently than interleaved memory,

but will function with mixed sizes of memory.
