What is PC Memory?

Desktop PC memory stores the programmes and applications that are running on a computer including the operating system. Referred to as RAM (Random Access Memory) and installed in the PC as modules typically in banks of 4 or 8GB the more memory a computer has the more easily it can cope with multitasking.

Upgrade Your Computers Performance With Desktop PC Memory

One of the easiest and cheapest way to improve the efficiency and performance of your computer is to install additional PC memory. Adding Random Access Memory, or RAM, to your computer will enable it to run more programmes and perform more simultaneous tasks. This is because increasing the memory increases the speeds at which the computer carries out different processes.

So, should you add memory to your computer? Multi-tasking without adequate memory will make the PC unpractically slow so if your computer is sluggish and is prone to freezing or crashing then installing additional memory should certainly help. Basically, the faster the speed and the higher the capacity of the memory the quicker the PC will accomplish tasks.

Upgrade Options

At Ebuyer.com we have a wide range of PC memory to choose from to enable you to upgrade your machine to cope with even the most complex and resource intensive tasks.

Find the PC memory you need according to the type, capacity, speed and form factor required. You can view the different upgrade options on the left of the screen.


Installing additional memory does of course involve physically adding a component to your computer. But even for the inexperienced, PC memory is fairly easy to install and a small screwdriver is the only tool needed.

Confused by memory? Don’t know your DRAM from your SRAM? Mystified by semiconductors, capacitors, and transistors? Not a problem. Help is at hand. We’ve put together this handy buyer’s guide to explain the ins and outs of PC memory; what it is, how it can improve your computers performance, and how you can choose the best memory for your PC. Let’s start by going back to basics.

What is PC memory?

The concept of PC memory can cause some puzzlement with computer users confusing it with storage memory. Understandable really. PC memory is more easily referred to as RAM (Random Access Memory) and performs very different tasks to storage memory which is found on a hard drive or SSD.

RAM, in the form of a memory module, is a component in your computer which enables short-term or temporary data access. This could be anything from loading a file or editing a spreadsheet. By contrast storage memory, for example a hard drive, allows long-term data access. In other words it will permanently store programmes, applications, and all your data files.

RAM memory determines how fast your computer accesses data. If your PC seems sluggish, upgrading the memory, i.e. increasing the RAM capacity, should speed it up appreciably. Because RAM and storage work together it is often best to upgrade your hard drive too. The general rule though, is the more RAM your machine has, the faster it will access data.

So RAM, or PC memory, is a vital component that has a big impact on the performance of our computer. So, we know we need memory. But, just to slightly muddy the waters again, there are two types of RAM.


There are two common types of PC memory; Dynamic (DRAM) and Static (SRAM). Of the two DRAM is the more common. It is cheaper, packs more data into a smaller space, and is the memory used in the vast majority of computers. You can find a huge range of DRAM modules from trusted manufacturers such as Kingston on the Ebuyer site.

SRAM, though faster, is expensive and more likely to be found in portable gadgets such as mobile phones though it can be found in cache memory (not something the average computer user needs to worry about).

Types of DRAM

When it’s time to select a new memory module you will find different types, capacities and speeds. Don’t worry, choosing new memory is not too complicated a task. But first of all…..

Here comes another acronym

Memory modules will be labelled with DDR (Double Data Rate) followed by a number. The number simply refers to the generation of the module, e.g., DDR3. The lower the number the older the technology. DDR3 is the most common memory type available however DDR4 is now established. However, the simple rule to remember here is that any new memory must be compatible with your motherboard. If you currently have DDR3 in your PC you cannot add DDR4 to it, you must use components from the same generation.

Why you should upgrade your PC’s memory

Adding more RAM to your PC is one of the easiest and most effective upgrades you can perform.

PC memory will speed up your computer

If your computer is running slowly, or you need to have multiple applications running simultaneously, installing additional memory will make it faster and more efficient.

How much memory should I add?

It depends. It’s a little simplistic but the general rule here is the more memory it has the quicker and more efficient the computer will be. How much memory you can add will depend on the number of RAM slots on your motherboard. Most motherboards will have either two or four slots which are assigned to a memory channel.

Memory modules can be purchased either singly or in kits. Best performance is usually attained by mounting memory in multiples so, for example, two 8GB modules will perform better, albeit slightly, than a single 16GB module. Memory can be purchased in various capacities from 2GB right up to 64GB though for everyday use including multimedia, web browsing and word processing, 8GB to 16GB in total will usually be more than adequate.

Installing the memory

The good news is that physically adding the memory to your machine is very easy, even for those who have never peeked inside a computer case before. It takes only a few moments.

installing pc memory

Match up the notches on the bottom of the memory with those on the motherboards slot and simply push into place.
