Installing extra memory What to consider

How to choose your memory

Use retailers' websites to determine what memory you already have.

Certain memory retailers' websites (including www.crucial.com/uk) have online programs that help you determine what memory is already installed. You may be required to download an ActiveX program (software created by Microsoft to enable interactive web content). It's OK to do this in this instance.

These memory detection tools report back on how much memory is installed, the amount of memory your PC will support and the number of free memory slots. Either buy memory directly from the online stores based on the recommendations provided or jot down the details and look to purchase your Ram elsewhere.

Safety first

Once your new memory's arrived you're ready to install it. Before you go rooting around inside your computer, however, you need to ensure that it's safe. Switch your computer off at the mains and remove any cables.

Remove the cover

First remove the screws located around the edges of the back panel of your computer chassis. The side panel adjacent to your computer ports should then slide off after applying mild force. Check with your manufacturer about warranty restrictions before you do this.

Before you install

Even the smallest of electrical charges can damage memory modules. To discharge any static, touch something metal before you start work and make sure you wear an anti-static wrist band (£5, PC World).

Locating your memory

The motherboard is the large circuit board that everything plugs into. The memory slots are near the central processor - look for a cluster of thin slots about five inches (12.5cms) long. If you can't reach your existing RAM then unplug any connectors that are in the way from the motherboard noting how they go back in.
