Installing Memory Modules - IBM Aptiva Hardware Handbook

modules. For example, you can have two 4MB
memory modules installed in Socket 1 and Socket 2,
and two 8MB memory modules installed in Socket 3
and Socket 4.
•
You can use either standard memory modules or
Extended Data Out (EDO) modules. You may use
both types, but you cannot mix them in the same
set. For example, if you install an EDO SIMM in
Socket 1, you must also use an EDO SIMM in Socket
2.
If you install EDO memory, you must use the Setup
Utility to configure each set (Bank) of sockets. Socket 1
and Socket 2 are Bank 1. Socket 3 and Socket 4 are Bank
2. For instructions on using the Setup Utility, see
page 69.
For more information on adding memory, see "Memory
module placement" on page 141.
Each memory module you install must have these
note: specifications: 72-pin; 32-bit or 36-bit; 4MB, 8MB, 16MB,
or 32MB; 70 ns; gold contacts; DRAM.

Installing memory modules

To install an additional memory module in an empty
socket:
1.
Find the notched edge of the module, and position
it as shown in step 2.

2.
Insert the module into the socket at a 45-degree
angle as shown. Make sure the connectors line up
and the module is firmly held in the socket at
approximately a 45-degree angle.
