Upgrading the AlphaPC 164UX
For higher system speed or greater throughput, you can upgrade SDRAM memory
by replacing DIMMs with those of greater size.
When configuring or upgrading SDRAM, observe the following rules:
•
Each DIMM must be a 168-pin unbuffered version and have a frequency of
100 MHz.
•
All DIMMs must be of equal size if they are in the same bank.
4.1 Upgrading SDRAM Memory
You can upgrade memory in the AlphaPC 164UX by adding more DIMMs or replac-
ing the ones that you have with a greater size.
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.
Open levers and align the DIMM.
4.
Firmly push the module into the connector. Ensure that the DIMM snaps into
the plastic locking levers on both ends.
5.
Restore power to the system.
