Basics Dual In-Line Memory Modules (DIMMs) - 8
Dual In-Line Memory Modules
(DIMMs)
The Power Macintosh 7200 Series and WS 7250 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.
Important:
The VRAM and DRAM Single In-Line Memory
Modules (SIMMs) used in previous Macintosh models are
not
compatible with the Power Macintosh 7200 Series and
WS 7250 computers.
