Installing memory
Your computer has two connectors for installing dual inline memory modules
(DIMMs) 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 synchronous dynamic random access
memory (DDR SDRAM), non-ECC DIMMs.
v Use 128 MB, 256 MB, 512 MB, or 1 GB DIMMs (when available) in any
combination.
Note:
Only DDR SDRAM DIMMs can be used.
To install DIMMs:
1. Access the system board. See “Accessing system board components and drives”
on page 12.
2. Locate the DIMM connectors. See “Identifying parts on the system board” on
page 13.
3. Open the retaining clips.
4. Make sure the notch in the DIMM aligns with the tab on the connector. Push or
insert the memory module straight down into the connector until the retaining
clips close.
5. Replace the PCI riser and adapters if it was removed.
6. Place the drives back to the original position.
7. Replace the cover. See “Closing the cover and connecting the cables” on page
25.
