A dual inline memory module (DIMM) consists of a number of memory
components (usually black) that are attached to a printed circuit board
(usually green). The gold pins on the bottom of the DIMM provide a
connection between the module and a socket on a larger printed circuit
board. The pins on the front and back of a DIMM are not connected.
168-pin DIMMs are commonly found in Pentium® and Athlon®
systems. 168-pin DIMMs are available in EDO, 66MHz SDRAM, PC100 SDRAM,
and PC133 SDRAM. When upgrading, be sure to match the memory technology
that is already in your system. (Information about which memory
technology your system uses is included in the Crucial Memory Advisor™
tool.)
The number of black components on a 168-pin DIMM can vary, but
it always has 84 pins on the front and 84 pins on the back, for a total
of 168. 168-pin DIMMs are approximately 5.25 inches long and 1.375
inches high, though the heights can vary. They have two small notches
within the row of pins along the bottom of the module.
