Upgrading SDRAM Memory
5.2 Upgrading SDRAM Memory
You can upgrade memory in the AlphaPC 164SX by adding more DIMMs or
replacing the ones you have with a greater size. Refer to Figure 2–1 for DIMM
connector locations.
Use the following general guidelines:
1. Observe antistatic precautions. Handle DIMMs only at the edges to prevent
damage.
2. Remove power from the system.
3. Align the DIMM so that the notch in the DIMM matches the key in the socket.
4. Firmly push the DIMM straight into the connector. Ensure that the DIMM snaps
into the plastic locking levers on both ends.
5. Restore power to the system.

64-bit-wide DIMMs can also be used.
