PRODUCT INFO:
DDR3 is the next-generation evolution of DDR2 and older DDR memory technology that will break the Gigahertz speed barrier for memory speed.

DDR3 is an industry standard technology defined by JEDEC. JEDEC is the semiconductor standardization body of the Electronic Industries Alliance (EIA). About 300 member companies representing every segment of the industry actively participate to develop standards to meet the industry needs. Kingston is a long-time member of JEDEC and is active on the JEDEC Board of Directors as well as a number of memory technology committees.

DDR3 memory features faster speeds, higher data bandwidths, lower voltage and power consumption, and enhanced thermal performance. DDR3 memory is engineered to support the next-generation quad-processors which require high data bandwidth to enable higher levels of performance.

DDR3 available on desktops, servers, notebooks, telecommunications/networking and other platforms in the following form-factors:

Unbuffered DIMMs, ECC or non-ECC
Registered ECC DIMMs
MicroDIMMs
SO-DIMMs
Custom Modules

DDR3 memory modules come in 1066MHz, 1333MHz and 1600MHz speeds (data rate)

DDR3 memory module components are show below (Unbuffered, Non-ECC DIMM for desktops shown):

DDR3 Components

DDR3 memory modules are not backward-compatible with DDR2 or DDR modules, due to incompatible pin configurations, voltage, and DRAM memory chip technology. DDR3 modules have a different "key" than DDR modules in the edge connector to prevent insertion into incompatible memory sockets.

JEDEC standard modules

Standard name	Memory clock	Cycle time	I/O Bus clock	Data transfers per second	Module name	Peak transfer rate
DDR3-800	100 MHz	10 ns	400 MHz	800 Million	PC3-6400	6400 MB/s
DDR3-1066	133 MHz	7.5 ns	533 MHz	1066 Million	PC3-8500	8533 MB/s
DDR3-1333	166 MHz	6 ns	667 MHz	1333 Million	PC3-10600	10667 MB/s[1]
DDR3-1600	200 MHz	5 ns	800 MHz	1600 Million	PC3-12800	12800 MB/s

A system with dual-channel memory will deliver twice the peak memory bandwidth listed above. For example, a PC3-8500 based system can deliver a peak memory bandwidth of 2 x 8.5 GB/sec or 17 GB/sec.

A system with triple-channel memory will deliver three times the peak memory bandwidth listed above. For example, a PC3-8500 based system can deliver a peak memory bandwidth of 3 x 8.5 GB/sec or 25 GB/sec.
