How to Find Your RAM Speed, Type, and Size on Windows and Mac

Knowing a couple of specs about your computer such as RAM can be helpful in different scenarios. For example, if you are facing some issues with the RAM or need more memory to improve the performance of the computer, you’ll need to know the RAM specs.

This way you’ll be able to figure out the right size, speed, and brand of the RAM to purchase in case you want a RAM upgrade.

In this article, we will guide you through the steps to follow if you want to learn your computer’s RAM specs like its speed, type, capacity, serial number, and so on.

Understanding RAM

What Is RAM?

RAM can be defined as the short-term memory that is responsible for storing data that can get deleted once they’re done. Short for Random Access Memory, RAM saves all the important information required for running your OS and other programs installed on your system.

It gives your device a higher processing capacity that handles data flows through the machine so that tasks are processed faster. So, if you have a higher RAM that means your system has more space to handle such tasks and a higher capacity to multi-task.

An obvious advantage of this is that the device can handle many applications at the same time and not hamper the machine’s performance.

Why Is It Important To Know How Much RAM Your Computer Has?

If you own a computer, ideally, you should know how much RAM it has. This will ensure that a certain application or game you want to get will run smoothly on the system.

Other than that, knowing how much RAM your computer can support and other details are required when you decide to upgrade your system’s RAM. Else, the purchase will go in vain and it will become a costly mistake.
