WARNING To avoid damage to your server, Apple Computer recommends that only an Apple-certified technician install additional DIMMs. Consult the service and support information that came with your server for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional DIMMs yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your server. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

DRAM configurations

Your server can use any DRAM configuration with DIMMs of these sizes: 8, 16, 32, or 64 MB. The exact configuration depends on the density of the DRAM chips that are mounted on the DIMMs.

You can increase your server’s DRAM to up to 512 MB. The main logic board has eight slots where DIMMs can be installed. To increase DRAM to

the maximum of 512 MB, have an Apple-authorized dealer or service provider fill all eight slots with 64 MB DIMMs. You can also fill slots with 8, 16, or 32 MB DIMMs.

Note: 128 MB DIMMs can fit in the server’s memory slots to increase DRAM to as much as 1 gigabyte (GB). These DIMMs have not been tested for use with Workgroup Server 8550 systems, however.

IMPORTANT The DIMMs should be 64-bit-wide, 168-pin fast-paged mode, with 70-nanosecond (ns) RAM access time or faster. The Single Inline Memory Modules (SIMMs) from older Macintosh computers are not compatible with your server and should not be used.
