When it comes to build up a new computer, you need to choose the components one by one. Processor, motherboard, hard disk are some of the key components of a computer system. RAM or Random Access Memory is equally important. Now the question arises whether to go for DDR2 or DDR3. DDR3 memory is the latest launch in the market. But is it ok to go with this version of memory? This article has been designed to give you some idea on which memory to choose. If you need tech support for computer repair, consult an expert.
There is a standards organization namely JEDEC that provide compatibility and interchangeability for computer memory. The job of this organization is to specify a number of factors such as speeds, timings, communication protocols, voltages, bank addressing, etc. in the design and development of memory DIMMs. And as per their comparison, DDR3 boasts some stunning features that make them stand tall.

We would like to start the comparison taking speed under comparison. As per official specification, speed of DDR2 ranges from 400 to 800 while DDR3 posses a speed range from 800 to 1600 according to the current JEDEC specification. The new Intel processors support the RAM of 1333 speed. It is true that the 1333 processors are compatible with any speed of DDR3 or DDR2 memory but for optimum performance DDR3 RAM with 1333 speed is the best choice.
From technological point of view, DDR3 is the best choice. It uses "fly-by" technology while DDR2 RAMs uses the "T branches". "Fly-by" is the latest technology and it employs automatic signal time delay created by the controller fixed at the memory system training. There is an automatic leveling circuit in the DDR3 DRAM chip for standardization and to memorize the standardization data.
In terms of use of internal banks DDR3 scores higher. It uses 8 instead of the 4 which is used by DDR2 to speed up the system. The benefit is that it reduces access latency which is quite evident if the DRAM is increased.
There has been significant improvement in terms of usage of memory voltage in the last couple of years from 2.5V with DDR to a notable improvement in DDR2 with 1.8V. And with DDR3 it is just 1.5V. This means 16% decrease from its predecessor. Further, this module of memory also features additional built-in power conservation features. For laptops, this is really a very useful feature.
There are plenty of other features that make it a better choice than its counterpart. DDR3 memory is a must for the computers with Core i7 processors. On the other hand, AMD Phenom II processors also recommend DDR3. So, for better computing experience, it is always suggested to go for DDR3 RAM.
