Dual In-Line Memory Modules
(DIMMs)
The computers in this manual ship with extended data output
(EDO) DRAM dual in-line memory modules (DIMMs)
instead of DRAM SIMMs. Whereas SIMMs have 72 pins,
DIMMs have 168 pins. The extra pins provide a 64-bit data
path, compared to a 32-bit data path for SIMMs. In addition,
DIMMs do not have to be installed in pairs like the SIMMs on
earlier Macintosh models. (However, to take advantage of
memory inter-leaving, the DIMMs should be installed in
paired slots. See “Memory Configurations” in Basics for
more information.)
Important:
The computers in this manual use +5 V DIMMs
only. Single In-Line Memory Modules (SIMMs) used in
previous Macintosh models are NOT compatible with these
computers.
