Upgrading the AlphaPC 164SX
For higher system speed or greater throughput, SDRAM memory can be upgraded
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.
• Each bank consists of two DIMMs and must be fully populated.
• Both DIMMs in the same bank must be of equal size.
5.1 Configuring SDRAM Memory
Although not an exhaustive list, Table 5–1 lists the tested SDRAM memory
configurations available. As additional configurations become available, they will be
posted in online revisions of this manual on the Alpha OEM World Wide Web
Internet site. See Appendix A for the URL.
For a list of vendors who supply components and accessories for the
AlphaPC 164SX, see Appendix A.
Refer to Figure 2–1 for DIMM connector locations.
Note: 1Mb × 72 and 1Mb × 64 DIMMs are not supported.
