Replacing memory
The computer has two connectors for installing dual inline memory modules that
provide up to a maximum of 2 GB of system memory.
When installing memory, the following rules apply:
v Use 2.5 V, 184-pin, double data rate static random access memory (DDR
SDRAM), non-ECC memory modules.
v Use 128 MB, 256 MB, 512 MB, or 1 GB memory modules (when available) in any
combination.
Note: Only DDR SDRAM memory moduless can be used.
To replace memory modules:
1. Turn off the computer and disconnect the power cord from the electrical outlet
and from the computer.
2. Disconnect all other cables attached to the computer.
3. Open the cover. See “Opening the cover” on page 25.
4. Access the system board. See “Accessing system board components and
drives” on page 27.
5. Locate the memory module connectors. See “Identifying parts on the system
board” on page 28.
6. Open the retaining clips to remove an existing memory module.
7. Make sure the notch in the replacement memory module aligns with the tab
on the connector. Push or insert the memory module straight down into the
connector until the retaining clips close.
