What is DIMM?
| Dual In-line Memory Module |
|
A printed circuit board with gold or tin / lead contacts and memory devices. A DIMM is similar to a SIMM, but with this primary difference: unlike the leads on either side of a SIMM, which are 'tied together' electrically, the leads on either side of a DIMM are electrically independent, ie actually separate circuits which allows for wider and faster data transfer. Successor of the SIMM memory module. The DIMM has 168 pins and a data path of 64 bit which is twice as much as the SIMM (72 pins, 32 bit). The biggest advantage of the DIMM is that only one module can be inserted into the mainboard when using a 64-bit CPU (like the Pentium or Pentium II). When using SIMM modules an even number must be inserted (2, 4, 6 or 8). Most DIMM modules are assembled with fast SDRAM memory chips which is twice as fast as EDO RAM. A useful option of the DIMM is the integration of an identification chip with type, serial number etc. |
