Dual In-Line Memory Modules 
(DIMMs)

 

The Power Macintosh 4400 uses DRAM on dual in-line 

memory modules (DIMMs). Three slots allow for memory 

expansion up to 96 MB using 3.3 V unbuffered 8-byte 

extended data output (EDO) JEDEC-standard 168-pin DRAM 

DIMM cards. DRAM expansion slot 1 only supports single-

bank DIMMs. DRAM expansion slots 2 and 3 support both 

single-bank and dual-bank DIMMs. No DRAM is soldered on 

the logic board.

 

The single in-line memory modules (SIMMs) 

used in previous Macintosh models are 

 

 compatible with  

4400 models. 

 

 use DIMMs that support a 4K refresh 

rate. Use 168-pin, 3.3 V unbuffered EDO, 60 ns or faster 

DIMMs. Also, the JEDEC MO-161 specification shows three 

possible heights for the EDO DIMM. For Macintosh
