Why has Apple transitioned memory expansion from 72-pin SIMMs to 168-pin DIMMs for Power Macintosh computers?
New Macintosh computers incorporating DIMMs provide a number of key advantages for an ever-increasing RAM footprint and memory-hungry applications (such as in multimedia development): * a wider 64 bit data path * higher memory capacity * greater flexibility because systems do not require DIMMs to be installed in complementary pairs.
