Installing memory

Your computer has three connectors for installing dual in-line memory modules (DIMMs) that provide up to a maximum of 1 GB of system memory.

Note: Your computer will only support DIMM 1 and DIMM 2 (from left to right). DIMM 3 will not be used due to mechanical restrictions.

Installing DIMMs

When installing DIMMs, the following rules apply:

vFill each system memory connector sequentially, starting at DIMM 1

vUse 3.3 V, synchronous, 168-pin, unbuffered, 133 MHz, nonparity, synchronous dynamic random access memory (SDRAM)

vUse 64 MB, 128 MB, 256 MB, or 512 MB DIMMs in any combination

vDIMM heights of 38.1 mm (1.5 inches)

To install a DIMM:

1. Remove the cover. See “Removing the cover” on page 17.
