How To Check RAM Speed on Windows , Linux and Mac

As the world is getting more and more digitalize the demand for Gadget’s specs to be high is increasing day by day. And your computer is one of the main characters of this whole digitalization world.

So, it is obvious that your computer should have great specification, to meet the modern requirements. It should have a great processor, a huge hard disk, and great RAM. 

Today, we are going to talk about one such component and that is RAM, as it is one of the most important ingredients in this dish which we call a computer.

What is RAM?

RAM, Random Access Memory is one of the most vital components of your computer. Higher RAM specs are something that will gravitate the buyer’s attention.

If you are going to buy a laptop or a desktop, there is a very thick chance that the first thing you are going to ask the vendor, will be about the RAM.

RAM Explained - Random Access Memory

Let’s say your budget was tight and you bought a computer with lower RAM. Now, as your requirement increases, you might want to increase your RAM’s capacity as well in order to achieve maximum performance.

This might leave you wondering “what is the maximum RAM capacity I can achieve?”. So, do not worry I got you covered. In this article, I am going to cover all of your doubts regarding the “How To Check RAM Speed” topic.

How To Check RAM Speed on Windows, Linux, and Mac

Before checking your RAM’s speed, you should first consider checking your memory as it will give a comparable knowledge of your current speed of the RAM.

In this article, we are going to discuss three main operating systems:-

  1. Windows
  2. Unbuntu Linux
  3. Mac

How To Check RAM Speed on Windows 10

Windows operating systems are one of the most common operating systems. From Windows XP to Windows 10, the Microsoft gem has ruled the operating system market over the years.

Check current RAM available:-

Since this Operating System is famous for its easy and user-friendly interface. So, checking the RAM is not a very difficult task for this operating system.

So, follow these few uncomplicated steps and you will be able to check your RAM.

There are Four methods in windows 10 by which you can see your RAM capacity:-

1. Task manager:-

Task manager is a place where you can see your system’s performance and in this method, we are going to identify your RAM’s capacity and its type with Task Manager in just two steps.

Step 1: Launch Task-manager via Task-bar, right-click on the taskbar+scroll to the third last option “Task-manager”. Or you can use this shortcut as an alternative cltrl+shift+Esc.

As you can see the RAM available in this example is 16GB and the type is DDR3.

2. This PC

This PC in Windows 10, is a place where your PC is integrated, and in this method, we are going to use “This PC” to sneak into your computer and find your RAM out

Note: we are just using Windows 10 as reference these methods is applicable for all versions of windows.

Step 1: Search “This PC” from your start menu. Click on “properties”.

3. Using System Information

Windows come with a utility named system information that you can access from the Start menu by search ‘system information“.

In the System Summary tab, You are able to view Installed physical memory, Total Physical Memory, Available Physical memory, Total Virtual Memory, and available virtual memory.

How To Check RAM Speed

4. Using DirectX Utility

Windows 10 comes with a tool named DirectX utility that will give you information about Directx components including BIOS version and installed RAM.

To access it, search for the “dxdiag” in the start menu. Under System tab, you are able to view the Installed memory.

Check RAM’s performance:-

RAM speed is something, that we all strive for. If your computer is lacking speed you might want to check your RAM speed first. So, for that, you have different third party applications. And we are going to use CPU-Z

Step1: After Installing CPU-Z from the above-provided link. Open the app.

Step 2:Launch the app and click on the memory option. You can see “DRAM frequency” the number written there is your RAM’s frequency. And since we have DDR RAM i.e; Double Data Rate. We are going to multiply it with two.

How To Check RAM Speed on Windows , Linux and Mac

In the above case, our DRAM frequency is 799.0 MHz. Therefore, your RAM’s speed is 1598.0 MHz.

Maximum RAM capacity:-

Now, since you know your RAM’s type and performance, you can think about adding more RAM to your system.

So, by obeying the following procedures, you can see how much RAM does your computer supports in the windows PC.

Step 1: Launch Command Prompt from the Start menu.

Step 2: Type command “wmic memphysical get MaxCapacity, MemoryDevices

How To Check RAM Speed on Windows , Linux and Mac

Note: the result here is in kilobytes if you want to change it to GB divide it by 1048576.

How To Check RAM Speed on Windows , Linux and Mac

As you see from the result above, the maximum RAM capacity of that particular PC is 32GB.

How to check your RAM for errors in Windows

If you are facing random PC issues like PC freezes or crashes then it’s time for you to check your computer RAM for an issue, luckily windows come with an inbuilt tool for this job named “Windows Memory Diagnostics“.

To access this tool, search for the “Windows Memory Diagnostics” in the start menu.

it will open like below image, if you want to check for problems then click on the Restart now option otherwise click on the “Check for problems the next time I start my computer”.

if this test is showing any error means it’s time for you to replace your RAM.

Free up memory on Windows 10

The best easiest way to free up RAM on your Windows PC is to use only the required applications that you want to use and close the remaining applications with windows task manager.

You can close the un-used application from the task manager, open the task manager by right-clicking on the taskbar, and select “Task Manager” option.

Under “Process” tab, select the applications that you don’t want to run and select the ‘End Task” option to end the task.

if you closely monitor your process tab, you will realize Google chrome is one most memory hog application.

I tried many tricks available on the internet to fix the google chrome memory hog issue and finally cam with a solution! 🤷‍♂️ Really, yes I changed my Google Chrome browser with Brave Browser (Download Here) which is also based on the same Chromium engine that Chrome is using.

The best part with chrome is it is using less memory then chrome and you are easily able to control with third-party trackers.

Below is the screenshot of my laptop after using the chrome.

Did you notice one point in the “System Information” screenshot there is one “Page File Space” memory and it’s also taking some RAM space. So the question is what exactly the page file is why it’s used? 🤔

In simple words, the page file is a small space in the hard drive that windows are using at the time of physical RAM completely full.

By-default once you shutdown the windows PC, your system RAM got cleared but still page file is stored. Clearing page file will help your PC to run effectively after the reboot.

Search for “regedit” in the Windows Start menu or search for the “Registry Editor” and navigate to below mentioned path

Navigate to this path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

How To Check RAM Speed on Windows , Linux and Mac

Double-click on the “ClearPageFileAtShutdown” option and change value of 0 to 1.
