Basics Dual In-Line Memory Modules (DIMMs) - 35
Power Macintosh/Performa 5500 Series
DIMM slots on the 5500 logic board accommodate 168-pin
5-volt EDO DRAM DIMMs. However, 3.3-volt EDO DIMM
cards are not supported and will not mechanically fit into
the DIMM connectors on the logic board.
The 8-byte DIMMs can be installed one or more at a time.
The 5500 logic board supports only linear memory
organization, and no performance gains result when two
DIMMs of the same size are installed. Any supported size
DIMM can be installed in either DIMM slot, and the combined
memory of all the DIMMs installed will be configured as a
contiguous array of memory. The largest DIMM supported is
a two-bank DIMM holding 64 MB.
