DDR memory

DDR memory ( Double Data Rate memory), is a new high performance type of memory that runs at twice the speed of normal SDRAM. This DDR SDRAM is ideally suited to the latest high performance processors to increase overall system speed. The faster the memory, the quicker DDR Memory PC 3200, PC2700 and PC2100 , PC2100 SO-DIMM - 184 pin, 200 pin instructions can be passed to the processor. DDR memory provides roughly a 15% boost in performance compared to regular SDRAM. With DDR memory now in the affordable price range, and motherboard manufacturers phasing out SDRAM on nearly every new board, it looks like DDR is definitely here to stay

It must be remembered that if you want to upgrade the memory of a computer that uses DDR1, you cannot buy a DDR2 module and use it to supplement a DDR1 chipset. The slots for DDR1, 2 and 3 are different. Some motherboards, however, have slots for all these DDR formats. The booklet on the motherboard should tell you how to install additional RAM on your computer. Sixty-four bit processors often support more than 3.5 GB of DDR RAM. A 64-bit Windows Vista system, for example, will support memory of up to 128GB.

A DDR RAM operates at a lower voltage than an SDR RAM, resulting in lower power consumption. Though it has the same architecture as an SDR RAM, a DDR RAM has 184 pins, instead of 168. It also has a single notch at the connector, not two. The bus width of DDR memory is 64 bits per channel. Most DDR-based chipsets come with matched pairs of modules and are made for processors that are 1GHz or faster.
DDR memory is the latest in high-performance memory module technological advances. It offers twice the data bandwidth of conventional PC100 or PC133 SDRAM, and is particularly well suited for high-performance servers and workstations, which need optimal CPU-memory performance.
