Your computer has either double data rate (DDR) or double data rate 2 (DDR2) memory. The type of memory required depends on the system board that is installed in your computer.

vIf your computer has just two memory connectors, your system board has DDR type memory. DDR memory modules are 184-pin, 2.5 V and can be used in any combination of 256 MB, 512 MB, and 1 GB sizes.

vIf your computer has four memory connectors, your system board has DDR2 type memory. DDR2 memory modules are 240-pin, 1.8 V and can be used in any combination of 256 MB, 512 MB, and 1 GB sizes.

To install a memory module:

1.Remove the computer cover. See “Removing the cover” on page 10.

2.Access the system board. See “Accessing system board components” on page 12.

3.Remove any parts that might prevent access to the memory connectors.

4.Locate the memory connectors. See “Identifying parts on the system board” on page 13.

5.Open the retaining clips.

6.Position the memory module over the memory connector. Make sure that the notch 1 on the memory module aligns correctly with the connector key2 on the system board. Push the memory module straight down into the connector until the retaining clips close.
