On Windows 10, the ability to check the technical specifications of the memory installed on your computer will come in handy in many situations. For example, when you have to resolve hardware and software related issues, details such as manufacturer name, part number and serial number will be useful when contacting technical support.

If your computer's performance is degraded due to memory-hungry applications or games, upgrading the memory can improve performance. In addition, knowing the memory specifications can also help determine the right size, speed and brand to facilitate the purchase of a compatible upgrade kit. When adjusting memory settings in the Unified Extensible Firmware Interface (UEFI) or Basic Input/Output System (BIOS), pre-recorded memory information can also help you understand if the configuration has been applied correctly.

While you can use Task Manager to view memory specification information, if you want to determine more specific details such as manufacturer, part number, serial number, etc., it is recommended that you use the command prompt.

Before entering any commands, first search for "cmd" in Windows, and then open Command Prompt as administrator.

Check the memory manufacturer

Type in the following command and press Enter:

wmic memorychip get devicelocator,manufacturer

Confirm the memory brand under the "Manufacturer" column.

Check the memory part number

Type the following command and press Enter:

wmic memorychip get devicelocator,partnumber

Confirm the part number under the "PartNumber" column.

Check the memory serial number

Type in the following command and press Enter:

wmic memorychip get devicelocator,serialnumber

Confirm the product identifier under the "SerialNumber" column.

Tip: In this command, you can also replace "devicelocator" with "banklabel" to list the serial number of the physical label that shows the memory on the motherboard.

Checking memory capacity

Using the command prompt, you can determine the total capacity of each module and the entire system.

1. Determine the capacity of each memory module

Type the following command, and then press Enter.

wmic memorychip get devicelocator,capacity

Under the capacity column, confirm the size of each memory module.

Tip: The capacity information is displayed in bytes, but you can convert the data to GB by dividing the number by 1,073,741,824 (1 GB byte).

2. To determine the total system memory capacity

Type the following command, and then press Enter.

systeminfo|findstr/C: "Total Physical Memory"

Confirm the total amount of physical memory (in megabytes) installed on the device.

Check the memory module speed

Type the following command, and then press Enter.

wmic memorychip get devicelocator,speed

Under the speed column, check the speed of the memory module (in MHz)

Check the memory type

Type in the following command and press Enter.

wmic memorychip get devicelocator,memorytype

Under the "MemoryType" column, confirm the number that identifies the memory type.

Check the memory form factor

Type the following command and press Enter.

wmic memorychip get devicelocator,formfactor

Under the FormFactor column, confirm the form factor information.

Note: If the output is 8, the device uses DIMM modules (usually available on desktops). Otherwise, if the command outputs the number 12, the computer uses a SODIMM module (usually available on laptops).

Check all memory details

The above command will help you determine the most useful information about the memory installed on your computer, but use another command to check all available details at the same time.

Type the following command and press Enter:

wmic memorychip list full

Confirm the information available for each memory module installed on the device.

After completing these steps, you will get a lot of detailed information about the memory modules installed on your Windows 10 computer.

Please note that while you can use the command prompt to look up many details about the memory specifications on your computer, some information may not be available depending on the hardware of your system.
