Working with System Memory
You can add memory to your computer to increase system performance.
Your computer has either two or three connectors (depending on the
model) for installing memory modules that provide up to a maximum of
256 MB or 384 MB (depending on the model).
Your computer uses dual inline memory modules (DIMMs). The
IBM-installed DIMMs that come with your computer are unbuffered,
synchronous dynamic random access memory (SDRAM).
When installing or replacing DIMMs, the following rules apply:
Fill each system memory connector sequentially, starting at DIMM 0.
Use only 3.3 V, 100 MHz, unbuffered, SDRAM DIMMs
Use only 16, 32, 64, or 128 MB DIMMs in any combination of
supported SDRAM DIMMs.
Note:
To locate the memory connectors on the system board, see
“Identifying Parts on the System Board” on page 62.
Installing and Removing a DIMM
Before you begin:
Read “Safety Information” on page vii and “Handling
Static-Sensitive Devices” on page 54.
Read the instructions that come with the new system memory.
Turn off the computer and all other connected devices.
Disconnect all cables attached to the computer and remove the
computer cover (see “Removing the Cover” on page 56).
Read “Accessing the System Board” on page 62 to learn the
location of the parts on the system board.
