Definition – What does DDR3 mean?

DDR3 (Double Data Rate Type 3) is a type of SDRAM that is used for system memory. The RAM is available to use in both DIMM and SO-DIMM form factors. It is similar to DDR2, but uses roughly 30% less power and can transfer data twice as fast. While the DDR2 RAM can transfer data at up to 3200MBps, DDR3 RAM support maximum data transfer rates of 6400MBps that means a computer with DDR3 RAM can transfer data to and from the processor much faster than systems with DDR2 RAM.

Glossary Web explains DDR3

DDR3 RAM modules look similar to DDR2 and DDR chips, but the gap that separates the two set of pins on the bottom of each module is in a different location. This prevents the RAM chip from being installed in a slot that does not support DDR3 RAM. Therefore, when upgrading your PC’s memory make sure you get the appropriate type of memory for your computer.
