Installing memory
Your computer has two connectors for installing dual in-line memory modules (DIMMs) that
provide up to a maximum of 512 MB of system memory.
Removing a DIMM
To remove a DIMM:
1. Locate the DIMM connectors. See “Identifying parts on the system board” on page 28 .
2. At both ends of the DIMM connector on the system board, slowly but firmly push outward
on the retaining clips until the module is loosened. Lift the DIMM out of the connector.
3. Store the DIMM in a static-protective package. Do not discard or lose this part. It might be
needed later if you change your memory configuration.
Installing DIMMs
When installing DIMMs, the following rules apply:
• Fill each system memory connector sequentially, starting at DIMM 0.
• Use 3.3 V, 133 MHz, unbuffered, SDRAM DIMMs.
• Use only 64, 128, or 256 MB DIMMs in any combination.
To install a DIMM:
1. To locate the DIMM connectors. See “Identifying parts on the system board” on page 28 .
2. If the retaining clips are not already open, open them.
3. Position the DIMM above the connector so that the two notches on the bottom edge of the
module align properly with the empty connector.
4. Firmly push the module straight down into the connector until the retaining clips pop up and
fit snugly around both ends of the module.
