Dual In-Line Memory Modules (DIMMs)

The Power Macintosh 9500 Series computers use 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 interleaving, the DIMMs should be installed in paired slots. See "Memory Configurations" in Basics for more information.)

Important: The Single In-Line Memory Modules (SIMMs) used in previous Macintosh models are NOT compatible with
