Chapter 1. Overview 3
Handling Static-Sensitive Devices
Have you ever walked across a carpeted floor, then touched an object and received
a small electrical shock? That's static electricity, and although harmless to you, it
can seriously damage computer components and options.
Important
When you add an option, do not open the static-protective package containing
the option until you are instructed to do so.
When you handle options and other computer components, take these precautions
to avoid static electricity damage:
Limit your movement. Movement can cause static electricity to build up around
you.
Always handle components carefully. Handle adapters and memory modules
by the edges. Never touch any exposed circuitry.
Prevent others from touching components.
When you are installing a new option, touch the static-protective package
containing the option to a metal expansion-slot cover or other unpainted metal
surface on the computer for at least two seconds. This reduces static electricity
in the package and your body.
When possible, remove the option and install it directly in the computer without
setting the option down. When this is not possible, place the static-protective
package that the option came in on a smooth, level surface and place the option
on it.
Do not place the option on the computer cover or other metal surface.

.9/ Video memory connector (some models only)
Note: An illustration of the system board and additional information are provided
on a label found inside the computer.
Working with System Memory
You can add memory to your computer to increase system performance. Your
computer has either two or three connectors (DIMM 0, DIMM 1, and DIMM 2) for
installing system memory modules. If your computer has three connectors, the
maximum amount of system memory your computer supports is 384 MB. If your
computer has two connectors, the maximum amount of system memory your
computer supports is 256 MB.
To locate the memory connectors inside your computer, see “Identifying Parts on
the System Board.” DIMM 2 is not on all models.
Chapter 3. Working with Options on the System Board 11
DIMM 0
DIMM 1
DIMM 2
The memory modules your computer uses are dual inline memory modules (DIMMs).
If your computer has an Intel Pentium II or Pentium III processor, the IBM-installed
DIMMs that come with your computer are non-parity or Error Checking and
Correction (ECC) 100 MHz Synchronous Dynamic Random Access Memory
(SDRAM) modules.
If your computer has an Intel Celeron processor, the IBM-installed DIMMs that
come with your computer are non-parity or ECC 66 MHz SDRAM modules.
However, not all models with an Intel Celeron processor support ECC memory.
When installing or replacing DIMMs, follow these guidelines:
Use only 3.3 V dc, unbuffered, 100 MHz DIMMs on models with Intel Pentium
II processors.
Use only 3.3 V dc, unbuffered, 66 MHz DIMMs on models with Intel Celeron
processors.
Each memory connector supports a maximum of 128 MB of memory.
Install only ECC DIMMs to enable ECC. If you mix ECC DIMMs and
non-parity DIMMs, your memory will function as non-parity DIMMs.
Memory Configuration
When you are adding or removing memory, you can use any combination of DIMM
sizes 16, 32, 64, or 128 MB. Be sure to fill each system memory connector
sequentially, starting at DIMM 0. For the location of DIMM 0, see “Identifying Parts
on the System Board” on page 11.
The following table shows possible memory configurations for your computer; this
table and additional information are also found on a label inside the computer.

Installing a Video Memory Module
The video memory module is a small outline DIMM (SODIMM).
Because not all PC 300PL and PC 300GL models have a connector for installing a
video memory module upgrade, the following instructions are for some computers
only.
If your computer comes with 4 MB of video memory, installing a video memory
module on the system board is not an option. To view the amount of video
memory of your computer, see the "System Summary" menu in the
Configuration/Setup Utility program (see Using Your Personal Computer).
