Why is RAM So Important for PCs?

If you’re in the process of buying a new computer, then you may find RAM is one of the many specifications you need to understand. RAM is very important for your PC, and it’s certainly something that needs to factor into your decision. Without enough RAM, your experience will be much slower, so you need to make sure you have enough.

Short Term Memory

RAM is like your computer’s short-term memory. It stores the most important information here for easy keeping, so when it needs it, it can access it extremely quickly.


This is important when running basic tasks and allows your experience to be much more seamless. For example, the most common tasks, such as switching between browser tabs, are instant because all the information is stored in RAM rather than longer-term memory. Without RAM, you’ll have a much slower experience, which, as we all know, is very frustrating.


RAM is all about allowing you to do things with speed. When an application is open, all the core information is stored on RAM, so the computer doesn’t have to keep searching through its memory every time you take an action.


It’s a little bit like when you’re on a quiz show. For the easy questions, the answer is easily accessible, but for the difficult ones, you have to spend time searching your brain for the answer.

When information is stored on RAM, your PC is going to find the answer to your request much more quickly.

Minimum RAM Requirements

When you are looking to buy desktop computer, RAM is an important consideration. RAM can make a big difference to your PC’s performance, but this will be reflected in the price. Not everyone needs a PC with a massive amount of RAM. The applications you use will tell you a minimum RAM requirement, so this can be a good guide for how much RAM you need.



If you’re using your PC just for basic tasks such as browsing the internet, then you may well not need extra RAM. However, if you’re purchasing your PC to play complicated games, or you’re using very powerful applications, then RAM is going to be much more of a consideration.


The more complex an application is, the more information your computer will need to store, and in order to access this quickly, it needs a good amount of RAM. If this isn’t the case, then you will experience lags while your PC searches for information on other memory storage devices.


Other Considerations

RAM is important, but it certainly isn’t the only consideration when it comes to buying a PC.

You may find you have adequate RAM, but other aspects are holding you back. A faster CPU or improved graphics card could unlock more potential for your computer, especially if you’re playing a lot of games. Again, it’s all about matching your PC to your specific requirements, and RAM is just a part of this. Take some time to write down what it is you want from a PC and if in doubt always ask a professional.
