1.9.2 Installing DIMMs

The procedure for installing DIMMs appears below. Please follow

these steps carefully. The number of pins are different on either side of

the breaks, so the module can only fit in one way. DRAM SIMM

modules have the same pin contact on both sides. SDRAM DIMM

modules have different pin contacts on each side, and therefore have a

higher pin density.

1. Make sure the two handles of the DIMM socket are in the "open"

position. i.e. The handles remain leaning outward.

2. Slowly slide the DIMM module along the plastic guides on both

ends of the socket.

3. Press the DIMM module right down into the socket, until you hear

a click. This is when the two handles have automatically locked the

memory module into the correct position of the DIMM socket.

To take out a memory module, just push both handles outward, and the

module will be ejected by the mechanism in the socket.

Note: We do not recomend the use of both SIMMs

and DIMMs at the same time, due to their different

voltages. This may result in unstable system

operation.
