What is Dimm?

DIMM, which means dual in line memory module, is a type of computer memory used on Pentium or higher computers. DIMM consists of a small plate with circuits that hold either four or nine (with a parity) synchronous dynamic memory of random access (SDRAM) or double data speed (DDR) SDRAM chips to the side. The connecting edge of the pins connects to the socket on the motherboard and transmits the data to the 64 -bits processor at once. DIMS can come in 64 -bit modules of the ECC errors (ECC) or 72 -bit parity modules. There are several types of DIMM; However, the three main types are SDRAM, DDR SDRAM and DDR2 SDRAM. DIMS ranges from 64 megabytes (MB) for older SDRAM to 128 gigabytes (GB) or more on the DDR2 RAM. These modules had one notch and two notches on each side on each side. 184-Pin DDR and 240-pipamus N DDR2 shares similar architecture, with two notches on each side and one notch along the connecting edge. The DDR memory has a clock accelerates up to 200 MHz andIt doubles the SDRAM data speed. The DDR2 memory has a clock accelerating up to 200 MHz and a data acceleration of four times the SDDRAM. Other types include DDR3 memory, higher speed and more expensive diversity and sodimmy for laptops.

By about 2000, DIMMS Simms or disposable memory modules as the standard of computer memory in Pentium computer systems. Unlike SIMM, which contained a 16 -bit or 32 -bit data path and demanded the addition of pairs to make full use of the 64 -bit Pentium PC data path, the data transmission speed of one DIMM perfectly fits the Pentium processor data bus, eliminating the need for pairs.

Another difference between two types of computer memory is the way in which the connects are connected. The connecting edges of both sides DIMM point to different circuits that respond differently to electrical signals. This adds more energy to the computing system, PRMore communication lines of the processor are possible. On the other hand, SIMM carries the same connectors on each side of the module and can manage one communication line with the processor.

Although DIMMS installation is a relatively easy process, DIMM memory types are not interchangeable. Always check the motherboard or PC manuals before replacing DIMM or make memory upgrades and check the type. First turn and disconnect your computer. Remove the case and look for memory slots on the motherboard. DIMM slots are usually black and are located near the processor. Distribute extra static electricity by touching a metal object.

Next, set the ejecting clips to the "down" position. Holding the memory module along the edges to avoid direct contact with the pins, align the notches on the connecting edge against the keyboards in the socket to match. Press the module to the location until it clicks and both ejectors fit on the module. Replace your computer cover, re -connect the cables and turn on the computer. In most casesThe system should recognize a new memory.
