Memory (Ram)
What is Memory and what does it do? RAM stands for Random Access Memory and is typically measured in megabytes. It is responsible for the speed at which the computer processes data and actions.
Why do I need one? The more RAM your computer has, the quicker it can access your programs and files. For example opening your web browser or playing a game. It also allows your computer to run more intensive applications as well as multiple applications at the same time.
How do I know what I need? The type of RAM you need depends on the motherboard you have and the type of socket it uses. They are different shapes and sizes. 2Gb of Ram will be sufficient for day to day use, internet browsing, watching films etc. 3Gb or more will be a better choice for those who wish to play games and use lots of programs on the computer.
Laptop computers use a different type of Ram to desktop Computers. As each type is different, they are not compatible with each other. There are two ways to determine which type of RAM your require. The best way to check is to open up your computer and see what type of RAM is already there. Alternatively you can use our Memory configurator.
This depends on whether it is for a laptop or desktop computer. Laptop memory is a different shape to computer memory so you have to select the right type for your needs.
What is available and what are the benefits of each? TSD RAM is an older style of RAM used in older computers.
DDR: This is a new type of RAM called Double Data Rate RAM. It is used in most computers and is faster than older SDRAM types.
DDR2: A newer style of DDR RAM which boasts extra performance due to the increased speed at which it runs.
DDR3: The latest, and most expensive of the 3 DDR RAM types. It is the fastest and best performing DDR RAM type to date. Brilliant for those who wish to run programs and games at their fastest.
RAM Modules come in a variety of capacities to suit all needs. The most commonly available are 512Mb, 1Gb, 2Gb and 4Gb.
RAM also comes in a variety of speeds which are identifiable by their "PC" number. These range from older style PC2700 for DDR RAM, to between PC3200 and PC6400 FOR DDR2 and between PC8500 to PC12800 for DDR3. Memory speed types are backwards compatible providing it is of the same type. DDR3 is not compatible with DDR2. For example a high speed PC6400 module can be used to replace an existing PC3200 module as it is still DDR2.
