If you have aWindows 11 laptopor 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 onWindows 11to quickly find out all the information without using Task Manager or third-party tools.
Thisguidewill 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.

To find out the memory manufacturer, use these steps:
Check part number
To determine the part number for each of the memory modules, use these steps:
Check serial number
To check the memory serial number, use these steps:
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:
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 Windows 11, use these steps:
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:
Check type
To determine memory type (such as DRAM, DDR4, RDRAM, etc.), use these steps:
Supported memory types
Here’s the list of the memory types that the command can detect:
Check form factor
To determine the memory sticks form factor (such as DIMM, SODIMM, etc.) on Windows 11, use these steps:
If the output is8, the computer usesDIMMmodules (usually available on desktops). Otherwise, if the command output the number12, the device usesSODIMMmodules (commonly used on laptops).
Supported form factor
Here’s a list of the form factors that the command can detect:
Check full specs
You can use the previous command to find specific information about the memory modules individually. However, you can also query all the memory specs with a single command on Windows 11.
To view all the memory details, then use these steps:
Once you complete the steps, you will have a full overview of the memory specifications.
