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.
