DDR 3 Ram Memory Configurations
DDR 3 Ram or double data rate 3 is a random access memory technology used for high speed storage of the working data of a computer system.
 
DDR 3 Ram is the 3rd generation of DDR memory , promising record speeds and a host of improvement over the old DDR 2 standards.
 
It is a part of the SDRam family of technologies , which is one of many Dram and is an evolutionary improvement over its predecessor , the DDR 2 Ram.
 
The DDR 3 ram has this ability to run its I/O bus at 4 times the speed of the memory cells it contains, thus enabling faster bus speeds and higher peak throughput. This achieved at the cost of higher latency. Also the DDR 3 Ram standard allows for chip capacities of 512Mbit to Gbit effectively enabling memory modules of maximum 16Gbytes in size.
 
DDR 3 Ram memory comes with a lower power consumption of approximately 16%.due to DDR 3 Ram 90 nm technology
 
The different standards of the DDR 3 Ram are :
· DDR 3 – 800       ( PC3 – 6400 )
· DDR 3 – 1066     ( PC 3 – 8500 )
· DDR 3 – 1333     ( PC 3 – 10600 )
· DDR 3 – 1600      ( PC 3 – 12800 )

DDR 3 Ram modules have 240 pins , the same number as DDR 2, but with a different key notch location.
 
The DDR 3 Ram prototypes were announced in 2005 , and products appear on the market in the form of motherboards based on Intel’s P35 “ Bearlake “ chipset .
 
Advantages of DDR 3 Ram versus DDR 2 Ram
 
- Higher bandwidth performance ( up to 1600MHz )
- Lower power consumption
- Improved thermal design ( cooler )
 
Disadvantages of DDR 3 Ram versus DDR 2 Ram
 
- Higher Cas latency
- Generally cost more than equivalent DDR 2 technology
 
Again , as I have mentioned before , you can always refer the latest models and pricing of the DDR 3 Ram memory module to your latest computer hardware store in your vicinity.
