Gallery: Find and fit the right PC memory

There are several ways to figure out what kind of memory to buy for your computer – from checking the manual or the manufacturer’s website to opening up the PC to physically identify the type of memory modules it uses. However, for the vast majority of people there’s a much simpler way – use an online memory finder tool. Just supply your computer’s make and model number, and the service will tell you exactly what kind of memory module is compatible with your computer. We’ve included links to two popular services (from memory manufacturers Crucial and Kingston) on our own website at www.computeractive.co.uk/2201722, so launch your web browser, type this into the Address or Location bar at the top of the screen and then press Enter.

When our website appears, click one of the links to be transferred to one of the listed memory finder services. We clicked the one for Crucial, an online memory retailer. Begin by using the various dropdown menus to select the computer’s manufacturer, type and model number, then click the Find It button. Other memory finder tools work in similar ways. Almost all modern computers use Dimms, although the exact type will depend on your computer. The tool should tell you what kind of memory modules your computer takes and the maximum amount of memory it can accommodate. If not, you may need to call the company instead. You now need to buy the necessary items - it’s up to you how and where you do this. At the same time, we’d advise buying an anti-static wriststrap - Crucial calls this tool an ESD Wriststrap - because it would be wise to have one when it comes to installation.

It’s time to put the modules into the appropriate slots. Regardless of the type of computer, this is generally an easy job, but it’s wise to proceed carefully. Begin by donning an anti-static wriststrap (follow the supplied instructions), then remove the case from your computer. This may involve undoing a few screws, or flipping a couple of levers. Either way, if you’re unsure how to proceed, consult the manual that came with your computer or call the manufacturer for guidance.

Peer inside your computer and look for the memory slots, using our picture of a desktop PC’s memory slots as a guide. Depending on how much memory you’re installing, it may be necessary to remove some existing modules, but most desktop computers tend to have spare slots. If you need to remove memory modules, flip down the retaining clips at either side of a module and gently, but firmly, pull it out and away from the slot. It should work free without great force.

Now open and unpack the memory modules. Holding them at the edges with your fingertips, inspect them for any signs of damage. You should avoid touching any part of the circuitboard. Decide which slot the memory module is destined for and then lower it into place, lining up the notch with the corresponding post in the memory slot. Push down on the top of the module: the retaining clips at either end of the memory slot should move up to lock it in place. Repeat the process for additional memory modules.

Now reverse Step 3, putting your PC back together. When all the casing panels and screws are back in place, start up the computer and watch the display for clues that the new memory has been identified. Most PCs will show the amount of memory available just after they are turned on. A message may be displayed and a series of short beeps may be emitted. If the computer doesn’t power up, turn it off, open it up and check that the memory modules are fully inserted.
