Memory and Microprocessor Configuration

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-bit unbuffered version and have a frequency of 100 MHz.

All DIMMs must be of equal size if they are in the same bank.

5.1Configuring SDRAM Memory

Although not an exhaustive list, Table 5–1 lists the tested SDRAM memory configurations available.

For a list of vendors who supply components and accessories for the AlphaPC 164UX, see Appendix A.

Refer to Figure 2–1for DIMM connector locations.
