Installing And Removing Memory Modules - IBM Aptiva Hardware Handbook

Installing and removing memory modules

If you have a desktop system, you may
have to remove installed adapter cards.
For instructions on removing adapter
cards, see page 92.
If you have a minitower system, you may
have to remove installed adapter cards
and the riser card. Follow the instructions
on page 113 to remove the adapter cards
and the riser card.
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 memory modules
installed in Socket 1 and Socket 2. For example, if you
have 8MB, a 4MB memory module is installed in Socket
1 and a 4MB memory module is installed in Socket 2.
For 16MB, two 8MB memory modules are installed.
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 a set. You must also use two memory
modules of the same size and type.
For example, if you install an 8MB memory module in
Socket 3, you must also install an 8MB 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 4MB memory module in Socket 3 and an
8MB memory module in Socket 4.
•
You can use two sets of different size memory
