How to Find your RAM Type, Speed, and Size on Windows 10 and MacOS

While computers are more popular than ever, the technicalities of hardware specifications can still be confusing for many. Your computer’s RAM (Random Access Memory) can be one of the most difficult areas to understand.

It doesn’t matter if you are upgrading RAM or building a custom computer, understanding computer hardware is essential. You need to be able to see what happens when the computer is running. This guide will help you determine your RAM size, type, speed, and other details.

Understanding RAM

You will need to know some basics depending on how advanced your computer skills are before you start the tutorial. If you know exactly what you are looking for, you can skip to the next step.

What is RAM?

RAM is the system’s memory. It stores all information necessary to run an OS or any programs that you use on your computer. RAM is a short-term memory bank that can be used on all tech devices (computers and smartphones, tablets, etc.). The SSD and HDD are faster for accessing files and running programs on a computer.


Your device’s CPU stores critical information, such as information about your operating system, apps and other information. However, RAM is limited in terms of the memory that can be stored on a CPU. This means your computer will run slower. The SSD or HDD must be used by the PC to temporarily store cache.

What RAM is your computer’s RAM?

It is important to know how much RAM your system has in order to make sure that a game or an application runs smoothly. Knowing your system’s capabilities will help you avoid disappointment and irritation.

If you are looking to upgrade your system, you may need to know details about your RAM. It is crucial to know what RAM you have and what compatible with the components that you plan to install.

How much RAM do you need?

It is easy to determine how much RAM you require. There is no reason to have less RAM than 4GB, as that is sufficient for most applications. 8GB RAM is sufficient unless you are a serious gamer, or use CAD and video editing software. If you are in this situation, 16GB RAM is recommended.


Windows 10: How to Find Your RAM Speed, Size, Type

It is easy to find out how much RAM your computer has. This information will not give you any insight into the performance of your computer, but it will let you know what your system can handle.

  1. To determine how much RAM your computer has, press ‘Win + I’ for access to your PC’s Settings.
  2. Click on and then “System.”
  3. Next, click ‘About’ and you can view your RAM to the right.

Windows 10 Command Prompt: View RAM Information

The best way to find out details about your computer’s RAM is to use the Windows 10 Command Prompt and PowerShell. Other built-in programs like “System Information” or “Control Panel”, only provide partial information such as the size, type, and/or both. This is how you can view detailed RAM information on your computer.

  1. Enter “cmd” in Cortana’s Search Box, then click “Command Prompt” to open the list.
  2. Enter the following code in the command prompt, and hit enter.
    wmic MemoryChip get MemoryType, Name, Capacity, Configuredclockspeed, DeviceLocator, FormFactor, Manufacturer, Serialnumber, Speed
  3. You can also add other aliases for more detailed information:
    ConfiguredVoltage DataWidth, MaxVoltage , CreationClassName, InterleavePosition
    Some aliases might not display any information.
    Type the following to see all possible aliases. Look under the “FULL” section.
    WMIC MemoryChip Listing /?

View RAM Information via Windows 10 PowerShell

  1. Right-click Windows 10 ‘Start Menu’, and choose PowerShell.” This task doesn’t require admin privileges.
  2. Enter the following code in PowerShell
    Get-CimInstance -ClassName Win32_PhysicalMemory | Format-Table Capacity, Manufacturer, MemoryType, FormFactor, Name, Configuredclockspeed, Speed, Devicelocator, Serialnumber -AutoSize
  3. You can find a complete list (Speed, Serial Number and FormFactor) of all properties. You can find more information on Win32_PhysicalMemory Properties.

Get Windows 10 Memory Details through CPU-Z

  1. Download CPUZ and execute the executable. Most likely, you will need the “CLASSIC VERSIONS” option.
  2. Navigate to the Tab “Memory to see how many slots you have and what type of memory is installed (DDR, DDR2, DDR3, DDR4, etc. The RAM size (GB) and its frequency. If you need it, you’ll be able to see real-time information about the RAM’s running frequency and a breakdown of latency/clock speeds.

Find your RAM speed, size, and type in macOS

It is easy to find the information you need about your memory, as with most Apple products. This process will allow you to see general information about your RAM.

  1. Click on the Apple logo to select “About This Mac” and your simple RAM information will be displayed under the “Overview”.
  2. You can request a more detailed report by clicking System Report. This breaks down components into tabs including memory, processor, and hard drive.
  3. To see the memory usage of your Mac running the most recent software, type “Activity Monitor”, then press Cmd + Spacebar, then click on the link to open it. Finally, select the tab.

You can also view real-time information about memory by opening “Finder”, clicking on “Applications”, then selecting “Utilities”, followed by “Activity Monitor” and finally choosing the “Memory” tab.

There are many options available to determine the RAM specifications, some more complicated than others. You can use CPU-Z to get a friendly GUI if you don’t like the command line tools.
