How to check RAM (size, speed, type, part, form factor) on Windows 11 (2024)

How to check RAM (size, speed, type, part, form factor) on Windows 11 (1)

If you have a Windows 11 laptop or desktop computer, understanding the system memory — or RAM (Random Access Memory) — specifications could be helpful 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 ready for an upgrade, understanding the RAM details can come in handy to determine the brand, speed, size, and other information you may need to get the correct modules to improve system performance.

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

This guide will walk you through the steps to determine the specifications for the memory installed on your computer.

How to check RAM specs with Command Prompt on Windows 11

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