Power Macintosh 5500 & 6500: Memory Expansion (5/97)
What type of memory is supported in Power Macintosh 5500 and 6500 series computers?
The Power Macintosh 5500 and 6500 series computers do not have any DRAM memory soldered on the logic boards. All RAM expansion is provided by DIMMs installed in one of the two 168-pin sockets.
The RAM expansion slots accept DIMMs with the following characteristics:
168-pin 5-volt EDO (Extended Data Out) DIMMs
64-bit wide
70 ns access time or faster
2K refresh rate
Acceptable DIMM sizes include 8, 16, 32, and 64 MB
EDO memory is the only supported memory type in these computers. Note however that 3.3-volt EDO DIMM cards are not supported and will not mechancially fit into the DIMM connectors on the logic board.
You cannot use Fast-Paged Mode (FPM) memory in Power Macintosh 5500 and 6500 series computers.
