Installing And Removing Memory Modules - IBM Aptiva Hardware Handbook

Installing and removing memory modules

Before beginning these steps, you may have to remove
installed adapter cards. For instructions on removing
adapter cards, see page 84.
Your system board has four memory module sockets
(labeled Socket 1, Socket 2, Socket 3, and Socket 4 in the
picture). Your computer comes with 8MB of memory, a
4MB memory module installed in Socket 1 and a 4MB
memory module installed in Socket 2. You can install
additional memory modules in Sockets 3 and 4. 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.
Socket 1 and Socket 2 work together as a set. Socket 3
and Socket 4 also work together as a set. When adding
or replacing memory modules, you must fill both

sockets in the set. Also, you must use two memory
modules of the same size.
For example, if you install a 2MB memory module in
Socket 3, you must also install a 2MB memory module
in Socket 4. Use these guidelines when adding memory
modules:
•
If you install a memory module in one socket, you
must also install a memory module in the other
socket in the set.
•
The memory modules you install in the two sockets
must be the same size. For example, you cannot
install a 2MB memory module in Socket 3 and a 4MB
memory module in Socket 4.
•
You can use two sets of different size memory
modules. For example, you can have two 4MB
memory modules installed in Socket 1 and Socket 2,
and two 2MB memory modules installed in Socket 3
and Socket 4.
For more information on adding memory, see "Memory
module placement" on page 107.
Each memory module you install must have these
note: specifications: 72-pin; 32-bit or 36-bit; 2MB, 4MB, 8MB,
16MB, or 32MB; 70 ns; gold contacts; DRAM.
