Random Access Memory or as more often called, the RAM or memory is learnt to have the maximum say in functioning of a computer precisely the speed or the performance of a computer. A Careful consideration while buying this computer component hence is one of the most vital things to do.

DDR3 has already gained an entry into the computing world , however the prominence of the DDR2 Still remains and would do for quite some time. Hence if you are looking to upgrade your desktop, then look no further than DDR2 or even DDR if you are still having the old system which is compatible only with the DDR Series of RAMs. DDR2 RAM’s are available in the speed range of 400 – 800 Mbps as an official standard, however there are also DDR2-1066 and DDR2-1266 available but are referred to as the Overclocked RAMs. You can look for the Speed of the RAM which would compatible with your system and go further to the next step.

Next comes the Memory Size, which makes more sense to all people – the technical and the non-technical ones. The memory size more prevalent these days is the 2GB though 1GB and 512 MB are available as an option for those looking for very basic , low to medium end desktops.

If you are looking to build a new PC and cannot wait to explore the new launched DDR3, then you should be prepared to grab some enhanced knowledge not just about the RAM’s but also the Motherboards and other components that would be compatible with the memory. DDR3 is expected to run at a speed of about 1600 MHz , that could make the desktop extremely power provided all things fall in place. They also run at a low voltage of about 1.5V or so. Intel is already learn to have announced an P35 chipset based motherboards compatible with the DDR3 Memory.
