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.
