Adding more memory

You can give your PC more memory by adding or replacing memory modules called “DIMMs”.

The motherboard’s two DIMM sockets accept DIMMs of up to 128 Mbytes in any combination (giving a maximum memory capacity of 256 Mbytes).

IMPORTANT

The DIMMs you use must have the following specification: gold contacts, 3.3V, 64-bit, unbuffered, either SDRAM-type with Serial Presence Detect (SPD) and a CAS latency of 2 at 66 MHz or else EDO-type with 60 ns timing. If you use any other type of DIMM you risk damaging the motherboard.

Fitting and removing DIMMs

Before you begin

1.Turn off the computer and unplug all power cords.

2.Take suitable anti-static precautions and remove the system covers. Take suitable antistatic precautions at all times while the motherboard is exposed.

3.Remove any expansion cards that impede access to the DIMM sockets.

To install a DIMM

1.Take the DIMM out of its anti-static packaging. Hold it by its ends and avoid touching the metal contacts.

2.Align the DIMM with the chosen socket, ensuring that the socket end clips are not obstructing.

◊The indents along the connector edge are asymmetrical to prevent the DIMM being fitted into the socket the wrong way round.
