Installing memory

Your computer has two connectors for installing dual inline memory modules (DIMMs) that provide up to a maximum of 2.0 GB of system memory.

When installing DIMMs, the following rules apply:

vFill each system memory connector sequentially, starting at DIMM connector 1.

vUse 2.5 V, 184-pin, 266MHz double data rate synchronous dynamic random access memory (DDR SDRAM).

vUse 128 MB, 256 MB, 512 MB, or 1.0 GB (when available) DIMMs in any combination.

vDIMMs are 38.1 mm (1.5 inches) in height.

Note: Only DDR SDRAM DIMMs can be used.

To install a DIMM:

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