DISCUSSION
The following table includes the memory configurations for desktop Power Macintosh computers. For information about upgrading the memory in another Macintosh computer, use the search string "memory configurations" to locate the following articles:
Note
: The Power Macintosh 7300, 7500, 7600, 8500, 8600, 9500, and 9600 series computers support memory interleaving. Although you can install DIMMs one at a time, you can get increased performance by installing them in pairs.
Note
: 128MB DIMMs are available and can fit into the memory slots on the Power Macintosh 7200, 7500, 7600, 8500, and 9500 computers. However, these DIMMs have not be tested with these computers and are therefore not supported by Apple.

Table Notes:
* Too many to list.
** The printed version of the Technical Information Guide does not contain this additional information: a Power Macintosh G3 in a desktop enclosure is capable of taking 128MB DIMMs. However, smaller 128MB DIMMs must be used due to space constraints. For additional information, refer to Tech Info Library article 24343, "
Power Macintosh G3 (Desktop): 128MB Memory DIMM Support
"
*** Only on the Revision 3 of the logic board. To identify which revision logic board you have, refer to article 24924: "
Power Macintosh G3: Identifying The Logic Board Revision
".
**** Although 2 GB can be physically installed, a maximum of 1.5 GB is recognized by the Mac OS Finder.
