A fast and simple way to sell DDR3 RAM Memory
DDR3 is the improved version of DDR2 with improvements in power consumption and bandwidth. The theoretical bandwidths of DDR3 range from 6.4 GB/s to 17 GB/s. The speeds of DDR3 start from 800 MHz, to 1600 MHz, to 2133 MHz. The speeds range from 6.4GB/s to 12.8 GB/s, to 17 GB/s.
The main advantage of DDR3 SDRAM over DDR2 SDRAM, is its ability to transfer data at twice the rate, allowing increased bandwidth. DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s. DDR3 dual-inline memory modules (DIMMs) have 240 pins and are electrically mismatched with DDR2. A key notch, which is positioned differently in DDR2 and DDR3 DIMMs, prevents inadvertently switching them. Not only are they keyed differently, but DDR2 has rounded notches on the side and the DDR3 have square notches on the side.
What is RAM?
RAM is an acronym or abbreviation for random access memory. RAM is a computer device that works as the short-term memory of a computer where data is stored temporarily. RAM has different speeds and versions and continues to improve with technology. DDR is the abbreviation for Double Data Rate. DDR3, and DDR4 memory are based on the design predecessor RAM SDRAM which stands for Synchronous RAM. This means that they synchronize things using a clock signal. Memories from the DDR category transfer two chunks of data in one cycle.
