Windows 11 check RAM specsSource: Windows Central

If you have a Windows 11 laptop or desktop computer, understanding the system memory — or RAM (Random Access Memory) — specifications may come in handy to troubleshoot problems with technical support or confirm the changes after tweaking the settings in the Unified Extensible Firmware Interface (UEFI).

Also, if the device is due for an upgrade, understanding the RAM details can help determine the brand, speed, size, and other information you may need to get the right modules to improve system performance.

Whatever the reason it might be, you can use Command Prompt on Windows 11 to find out all the information quickly without using Task Manager or third-party tools.

In this Windows 11 guide, we will walk you through the steps to find out the specifications for the memory installed on your computer.

How to check RAM specs with Command Prompt on Windows 11

Using Command Prompt, you can determine many details about the system memory installed on the computer, including manufacturer, part and serial number, capacity information, speed, type, form factor, and more.

Although you can use Command Prompt to query many different details about the system memory, some information may not be available depending on the hardware.

Check manufacturer

To find out the memory manufacturer, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to determine the memory manufacturer name and press Enter:

    wmic memorychip get devicelocator, manufacturer

    RAM manufacturerSource: Windows Central

  4. Confirm the memory manufacturer name under the "Manufacturer" column.

Check part number

To determine the part number for each of the memory modules, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to determine the memory part number and press Enter:

    wmic memorychip get devicelocator, partnumber

    RAM part numberSource: Windows Central

  4. Confirm the product number under the "PartNumber" column.

Check serial number

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to get the RAM stick's serial number and press Enter:

    wmic memorychip get devicelocator, serialnumber

    RAM serial numberSource: Windows Central

  4. Confirm the product serial number under the "SerialNumber" column.
  5. (Optional) Type the following command to find out the physical location of the stick on the motherboard and press Enter:

    wmic memorychip get banklabel, serialnumber

Check capacity

On Windows 11, you can also use different commands to determine the total system capacity or capacity per module.

Determine capacity per module

To find out the amount of memory available in each stick, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to determine each module capacity and press Enter:

    wmic memorychip get devicelocator, capacity

    Memory module capacitySource: Windows Central

  4. Confirm the amount of RAM per module under the "Capacity" column.

Since the capacity is returned in bytes, you have to divide the number by 1,073,741,824 (1 gigabyte in bytes) to convert the information into gigabytes.

Determine capacity total

To determine the total amount of RAM installed on a Windows 11 device, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to determine the total amount of RAM installed on the computer and press Enter:

    wmic computersystem get totalphysicalmemory

    Windows 11 total system memorySource: Windows Central

  4. Confirm the amount of RAM per module under the "Capacity" column.

To convert the information to gigabytes, you must divide the number by 1,073,741,824 (1 gigabyte in bytes).

Check speed

To find out the speed of the memory modules, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to check the memory speed and press Enter:

    wmic memorychip get devicelocator, speed

    RAM speed Source: Windows Central

  4. Confirm each of the memory module's speed under the "Speed" column.

Check type

To determine memory type (such as DRAM, DDR4, RDRAM, etc.), use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to check the memory type and press Enter:

    wmic memorychip get devicelocator, memorytype

    RAM memory typeSource: Windows Central

  4. Confirm memory type under the "MemoryType" column.

Supported memory types

Here's the list with the memory types that the command can detect:

  • 0: Unknown.
  • 1: Other.
  • 2: DRAM.
  • 3: Synchronous DRAM.
  • 4: Cache DRAM.
  • 5: EDO.
