How to Install a Memory Module

Before You Begin
Caution – Dual inline memory modules (DIMMs) are made of electronic
components that are extremely sensitive to static electricity. Static from your clothes
or work environment can destroy the modules.
Do not remove any DIMM from its antistatic packaging until you are ready to install
it on the main logic board. Handle the modules only by their edges. Do not touch
the components or any metal parts. Always wear a grounding strap when you
handle the modules.
Complete these tasks:
"How to Power Off the System" on page 26
"How to Remove the Side Access Panel" on page 31
"How to Avoid Electrostatic Discharge" on page 35
For information about memory configuration, see "About Memory" on page 47.
What to Do
1. Remove the new memory module from its antistatic packaging.
2. Locate the socket into which you will install the module.
See "About Memory" on page 47.
Note – Each bank used must contain four modules of equal capacity (for example,
four 32-Mbyte memory modules, four 64-Mbyte modules) to function properly. Do
not mix capacities within the same bank. See "About Memory" on page 47.
3. Orient the module so that the small notch on the bottom corner of the module is
at the same end as the socket's ejection lever.
