The DIMM is larger than either of the SIMMs.  They contain 168 pins on the bottom of the circuit board.  There are two notches on the bottom of the board and they must be aligned properly in order for them to be inserted.  These memory modules are primarily used in newer computers and can be inserted one at a time unlike the SIMMs, which have to be inserted in pairs.

168-pin DIMMs are found in Pentium and Athlon systems. Each 168-pin DIMM provides a 64-bit data path, so they are installed alone in 64-bit systems. 168-pin DIMMs are available in FPM, EDO, PC66, PC100 and PC133.

The number of chips on a 168-pin DIMM may vary, but they have 84 pins on the front and 84 pins on the back for a total of 168. 168-pin DIMMs are 5.375" long and 1.375" high, and the heights may vary. They have two small notches within the row of pins along the bottom of the module.
