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.
164-bit-wide DIMMs can also be used.
