What Is a Memory Module?

A memory module is a narrow, printed, circuit board that holds
memory chips. A memory module is inserted into a memory
module slot.
Your notebook has 2 memory module slots, a primary memory
module slot and an expansion memory module slot.
Memory modules increase random access memory (RAM).
Advanced users can change the speed at which the notebook
runs graphics applications, such as 3-D video games, without
increasing RAM. For information about this procedure, refer
to "Video Memory Settings,"

Primary Memory Module Slot

All models of your notebook ship with a memory module
installed in the primary memory module slot. The primary
memory module slot should be accessed only by a service partner.

Expansion Memory Module Slot

Depending on your notebook model, the expansion memory
module slot on your notebook may be vacant or may contain
a replaceable memory module. Procedures for installing or
replacing a memory module in the expansion memory module
slot are provided in
later in this chapter.
