Basics SDRAM DIMMs - 64
profile DRAM DIMMs must be used to reach the maximum
DRAM expansion of 384 MB. Using higher-profile DRAM
DIMMs, the maximum DRAM expansion for the Power Mac
G3 Desktop is 192 MB.
The DRAM DIMMs can be installed one or more at a time. The
logic board supports only linear memory organization.
Therefore, no performance gains are seen when two DIMMs
of the same size are installed. Any supported size DIMM can
be installed in any DIMM slot, and the combined memory of
all the DIMMs installed will be configured as a contiguous
array of memory.
Important: Power Macintosh G3 computers use SDRAM
DIMMs. DIMMs from older Macintosh computers are not
compatible and should not be used even though they fit into
the Power Mac G3 DRAM DIMM slots.
