What is DDR3?

A:

Quick Answer

DDR3 is the third generation of Dual Data Rate RAM (Random Access Memory). RAM is used to store pieces of data for immediate and random access by a computer. Without RAM a computer will not power up, as it is an essential component that even the Basic Input/Output System requires.

Full Answer

DDR3 was introduced for consumer implementation in 2007. DDR3 has a high bandwidth, compared to previous versions of RAM, therefore it is an excellent solution for intensive computer use.

The most common type of DDR3 RAM is DDR3 SDRAM. This is an abbreviation for Double Data Rate Type Three Synchronous Dynamic Random Access Memory.

DDR3 is not compatible with any other platform. DDR3 can't be used in a motherboard built for DDR2 or any other type of RAM because of significant differences in voltage, timing, latency and form factor. DDR3 SDRAM is built in a similar way to previous versions of memory; the main difference is the interface.

The title "DDR3" does not provide any insight into the build or quality of the RAM. It is merely an interface specification. With each new generation of DDR SDRAM, the transfer speed typically doubles and the maximum capacity per module increases. Therefore, DDR3 has a clear advantage over previous generations of RAM.
