Installing System Memory Modules - IBM Aptiva Handbook

Installing system memory modules

Your system board has four system memory module
sockets, labeled socket 1 through socket 4. These
sockets hold single inline memory modules (SIMMs).
If your computer comes with 8MB installed on the
system board, your SIMM sockets are filled in one of the
following configurations:
•
One 8MB module in socket 1
•
One 4MB module in socket 1 and one 4MB module
in socket 2
•
One 4MB module in socket 3 and one 4MB module
in socket 4

If your computer comes with 16MB installed on the
system board, your SIMM sockets are filled in one of the
following configurations:
•
One 16MB module in socket 1
•
One 8MB module in socket 1 and one 8MB module
in socket 2
•
One 8MB module in socket 3 and one 8MB module
in socket 4
•
One 8MB module in socket 1, one 4MB module in
socket 3, and one 4MB module in socket 4
To upgrade your system memory, you can install
additional memory modules. You can also replace the
existing memory modules with modules that have
higher memory capacity. The maximum amount of
memory you can install is 128MB.
If you add or replace system memory modules, you
must follow these guidelines:
•
You can have a module in socket 1 without putting a
module in socket 2.
•
If you put a module in socket 2, you must have a
module in socket 1.
•
If you have modules in sockets 1 and 2, the modules
must have the same specifications.
•
If you add a module to socket 3 or 4, you must have
a module in both sockets and these modules must
have the same specifications.
