How to upgrade or add more memory to your computer

As a computer repair technician, I get many questions about how to speed computers up. Adding more memory has always been the best 'bang for the buck' when improving your computer's performance. And it's pretty easy to do. Here's how to upgrade or add more memory to your laptop or desktop computer.

When you start to look at upgrading your computer's memory, you need to know three (3) things: the type of memory it uses, how much memory you currently have, and the maximum amount of memory your system can handle. Computer memory is installed into slots on the motherboard. Laptops use SO-DIMM (Small Outline Dual In-line Memory Module) slots, and desktops use DIMM (Dual In-line Memory Module) slots. The amount of memory slots varies from a laptop (1-2) to a desktop (2-8). High-performance motherboards, like the ones used in servers, can have 16 or more memory slots.

There are a couple of ways to find out your computer's memory specs. The first is the tried-and-true method: reading the manufacturer's manual (either system or motherboard) and physically checking the slots in the computer (some laptops have memory slots in two different locations). You can also download a program like CPU-Z to find out what type of memory your computer has. In some cases, you may have to replace the existing memory modules with larger ones instead of just adding more memory.

If you are planning on adding more memory, you want to make sure the timings match between the existing memory and the new modules. Mixing memory modules with different timings can affect your computer's performance. You should always try to add or upgrade memory in pairs.

Once you know what type of memory you need, it's time to purchase it. You can buy it online or locally. But remember, if you need to return it, it's easier to do it locally. Also, if you need two or four memory modules, many vendors offer twin and quad packs for less than the individual price. Once you have your new memory, it's time to install it.

Note: Remember to disconnect the power going to the system before working on it.

• Desktops - Disconnect the power cord going to the computer
• Laptops - Disconnect the AC charger and remove or disconnect the battery
