How to Check How Much RAM do You Have

How Much RAM do I have

Did you know that a computer’s RAM capacity determines the number of open files and application programs that it can process concurrently? Now you know. So, how much RAM do I have? Let’s find out….

A computer’s processing capacity and speeds are determined by, among other factors, the amount of RAM installed. The more of it, the better the PC’s performance.

If your computer has less RAM, you might have to deal with frequent slow speeds, sluggishness, endless spinning wheels, and even error alerts notifying you of the computer's low memory status. Also worth noting is that the latest RAM models are considerably better than previous versions in terms of speed and overall performance.

Before we get to the specifics of knowing how much RAM your PC has, let’s begin with some basic definitions.


What’s RAM?

RAM stands for Random Access Memory, and it’s basically your PC’s physical or working memory. This hardware component acts as the speedy short-term storage for temporary data for instant access by the CPU.

Simply put, when you click to launch a computer program like you do when you want to access a video or word document, the file is transferred from the PC’s storage drive to the RAM to make it readily accessible by the central processing unit. The Random Access Memory is located between the CPU and HDD or SSD storage drives.

How to Check RAM on Linux Operating System

 

Checking RAM on Linux is not as straightforward as is the case with Windows or Mac operating systems. Here you’ll use commands. And there are a number of them. Some of the Linux commands you can use to access memory information include “free”, “vmstat”, “/proc/meminfo”, and “dmidecode”. In this post, we’ll only discuss how to check RAM using the “free” command. Below is a quick summary of the steps to follow:

Step 1: First, run/launch/ initiate the Terminal, which is very similar to the Windows CMD interface on your PC.

  • Tip! In order to see your system’s memory utilization in MBs, use the “free” command with the “-m”.

The free command will output info about the memory (actual RAM) and virtual memory (swap). On your screen, you’ll notice that both these variables are categorized into total, used, free, and shared. Using the “free” command with “-h” makes the output much easier to read and interpret.

If you want the display to be in columns for easier comparison of the amount of RAM and swap on your system, use the “free” command with the “-t” option.

To see the system memory utilization by installed applications, use the command “top”.


Windows Memory Diagnostics: Check Your RAM for Errors

Whenever you experience frequent or random system crashes, restarts, or system freezes on your computer, it’s about time you checked the system memory to see if you’re dealing with hardware failures. Windows 7, 8, 10, and 11 all have this awesome feature called Windows Memory Diagnostics, whose main function is to check your PC’s memory for potential system problems.

The utility feature provides you a detailed breakdown of the health of your system’s RAM. If, after running the tool, some errors are detected in your Random Access Memory, consider buying a new RAM chip in order to keep your PC running at its optimum.


When to Upgrade RAM

Upgrade RAM

Not sure whether or not your PC needs a RAM upgrade? Look out for these pointers: Painfully slow speeds even after system optimization, random crashes, “running low on memory” reminders, and auto-restarts. If you experience any or all of these telltale signs routinely, then you’re a candidate for a RAM upgrade.

And in case you didn’t know, RAM is super easy to install on most PCs. As long as you can comfortably open the bottom cover of your computer and have the new RAM handy, an upgrade is as easy as unplugging your old RAM and slotting in the new one.

Note, however, that some PC models and Macs have their RAMs embedded onto the motherboards. In such cases, an upgrade can be a little cumbersome. You may want to seek the services of an expert to help with the upgrade if you’re having trouble doing it on your own.

How to Free Up RAM

When your PC’s RAM is filling up, the computer will present with all the cardinal pointers of hardware malfunction. Usually, what happens when your RAM is packed to near capacity is that the operating system will try to compensate by extending the functions of RAM to the hard drive, a phenomenon called paging.

The whole compensatory process, though it makes up for the memory insufficiency, comes at a huge cost in terms of system performance. To remedy the low RAM problem, all you need to do is free up some memory space. Here’s how to free up memory space the easy way on Windows or Mac operating systems.

How to free up RAM on Windows

The quickest way to free up memory space on windows is to make use of the Task Manager utility.

Step 1: Launch the tool by typing “Task Manager” in the search tab, then go ahead and open the application.

Note that some programs, though closed, are set to continue running in the background. Even so, you should see a considerable boost in system performance after closing most of these hog applications.

How to Free Up RAM on MacOS

 

Devices that are powered by the Mac operating system, such as iMac and MacBooks, can readily run out of memory. This is especially true for devices that have a RAM of 4GB or less.

Here’s how you can free up some memory space on your Mac:

Step 1: On the macOS top menu bar, click on Go. Then on the menu options, select Utilities.

Go Utilities

Step 2: Next, double-click on the Activity Monitor. A window of all the apps that are currently active on your PC will appear.
