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.

64-bit-wide DIMMs can also be used.
