DDR&DDR2 1GB/2GB RAM Memory




























A dual inline remembering ability (DIMM) consists of a separate of remembering components committed to a printed track timber. The metallic pins on the lower of the DIMM ply a connection between the power and a socket on a printed racecourse dwell. The pins on the side and punt of a DIMM are not adjunctive to apiece opposite.

DDR2 SDRAM use 240-pin DIMM sockets for screen computers. Apiece 240-pin DIMM provides a 64-bit assemblage track (72-bit for ECC or listed modules), so they are installed one at a reading in 64-bit systems. DDR2 chipsets are due to concur dual-channel remembering, providing a 128-bit collection course.

Store modules (Unbuffered, Listed, Fine Scheme DIMMs) have a primary "key" or notch in their connector. These keys moldiness adjust with a key in the faculty socket to portion the ability to be inserted. All DDR3 and DDR2 ability types are keyed differently.

To use DDR3 storage, your grouping motherboard staleness score 240-pin DIMM slots and a DDR3-enabled chipset. DDR3 modules use a 1.5V land ply, providing a big country action over the 2.5V DDR modules or 1.8V DDR2 modules. DDR3 is the succeeding multiplication of Flex Collection Grade (DDR) Coinciding Dynamical Ergodic Access Module (SDRAM). It is an evolution of DDR and DDR2 retention application that delivers higher speeds, berth land demand and emotionality dissipation.
