What is a RAM?

RAM (Random Access Memory) is part of the main memory and act as a temporary storage, communicating with your computer processor.  It interacts with your computer processor allowing it to multi task or run multiple programmes that runs at the same time efficiently.  Your computer must have RAM to operate.  RAM is a form of flash memory and is faster than a hard drive memory as it takes less time to find and send out its stored information.

Slow computer – not enough ram

If you don’t have enough RAM in your computer and you have too many programmes opened at the same time then your RAM will overload. If you overload your RAM by having too many programmes open at one time, then data your computer processor needs, must be taken from your computer’s hard drive. This will cause your computer to slow down as it takes longer for a computer to retrieve information from your hard drive.

How to check how much ram your computer has?

To find out how much RAM your computer has:

1.       Open System by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking System.

2.       In the System section, under Memory (RAM), you can view the amount of RAM your computer has.

How much RAM your computer should have?

Here are the minimum requirements of ram for different operating system:

Windows XP – Minimum 1GB of RAM

Windows Vista – Minimum 2GB of RAM

Windows 7 – Minimum 2GB of RAM

Windows Vista and Windows 7 have more features than Windows XP, and they must dedicate more memory into RAM.


Types of RAM

Before performing any RAM upgrade, it is very important to determine what type of memory modules your computer can accommodate.  Here is the different types of RAM a computer uses:

DDR Memory – if your computer is old then it might take double data rate or DDR memory.  When DDR memory first came on the market, it was able to transfer data twice as fast as its predecessors.  DDR transferred at speed of up to 3.2 gigabytes per second and this was a huge improvement in terms of memory speed.

DDR2 memory – a few years after the introduction of DDR ram, the DDR2 came along.  The DDR2 ram attained data transfer rates of up to 8.5 gigabytes per second and in addition DDR2 offered “dual-channel mode” capability.

DDR3 memory – if you have recently purchased a new computer then it probably uses a DDR3 memory.  DDR3 operates at a lower voltage and uses less power than DDR and DDr2.  DDR3 transfers data up to 12.8 gigabytes per second.  DDR3 can operate in dual-channel and triple-channel modes.

Where to buy RAM from?

If you feel like you do not have enough RAM in your computer for the amount of multi-tasking your computer does then you should consider purchasing more RAM.  A great website to purchase RAM form is . will tell you what type of RAM your computer uses, how much RAM your computer can handle, and sells you the RAM you need at a reasonable program.  To find out more please visit their website.  Another good site where you can purchase RAM form is .  This site offers free and fast shipping and their price is very reasonable.

You can buy RAM from your local electronic stores such as PC world, Currys or best buy but they often charge more than online stores.  When buying your RAM make sure that you are buying the correct one for your computer.  If you need assistant refer to your system specification or guide for details.  If you are unsure then its best to get your computer checked by a IT technician who should be able to tell you exactly what you need.
