Dual In-Line Memory Modules 
(DIMMs)

 

The 5400 series and 5500 use DRAM Dual In-Line Memory 

Modules (DIMMs) instead of DRAM Single In-Line Memory 

Modules (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.

 

The SIMMs used in previous Macintosh models 

are 

 

 compatible with the 5400 series or the 5500. The 

5400 series requires DIMMs with refresh rate of 2K.
