Many aspects of the personal computer have increased in leaps and bounds in terms of performance and what they are capable of doing.

Computer memory, often referred to as Random Access Memory (RAM), has become of greater and greater performance as time has gone on.

One of the famous quotes from back in the eighties was one made by Bill Gates when he said that no one would ever need more than 640KB of memory. Well that has been passed for ages now, with high performance machines sometimes sporting over 1GB of it.

Why choose DDR memory?

DDR (double data rate) is an evolutionary memory technology based on SDRAM. The DDR SDRAM access is twice as fast as SDRAM, as data transfers occur on both edges of the clock. It is fast, transferring data up to 2133MB/s. It also consumes less power than the conventional SDRAM or other types of memories, with an operational Vcc of just 2.5Vcc instead of 3.3Vdc for SDRAM.

Which DDR do you buy?

Depending on your preference and your system, you can get any of the DDR memory available in the market (DDRI, DDR2 or DDR3). Selecting the right DDR variant is a very important factor in determining the overall performance of your system.

There are many advantages that can be had with more memory.

• Programs run faster
• Less waiting time for programs to load
• More programs can be run at a time
• Overall computer speed is increased
