 Here's how to check the number of RAM slots and maximum RAM capacity using Command Prompt

Sometimes, it becomes mandatory for a user to upgrade or change the RAM; the reasons can differ. While upgrading or changing the RAM, a question might come into the user’s mind, i.e., what is the maximum RAM capacity supported by his laptop.In some scenarios, your laptop became short on memory (especially in old gaming laptops). In this case, you also need to upgrade the RAM. And this time, you might want to upgrade it to the maximum RAM capacity, but you didn’t know how much RAM you could extend. So that’s why we bring two easy tutorials for you to check how much RAM your laptop can support.

1. Open Command Prompt as administrator:

• Windows 11: Right-click the Start menu and select "Command Prompt (Admin)".
• Windows 10: Press Windows key + X and select "Command Prompt (Admin)".

2. Check the number of RAM slots:

• Type the following command and press Enter:

wmic memphysical get memorydevices Or Wmic memphysical get Maxcapacity

• The output will show the number of RAM slots and other information about the RAM banks. Look for the "MemoryDevices" value. The number displayed is the number of available RAM slots.

3. Check the capacity of installed RAM:

• Type the following command and press Enter:

wmic memorychip get devicelocator, capacity

• This will display the capacity of each installed RAM module.

4. Check the maximum RAM capacity supported by the motherboard:

• Type the following command and press Enter:

wmic memphysical get maxcapacity

• The output will show the maximum amount of RAM supported by your motherboard in kilobytes. Divide this number by 1024 to get the maximum capacity in megabytes.

Example:

C:\> wmic memphysical get memorydevices

MemoryDevices   8

C:\> wmic memorychip get devicelocator, capacity

DeviceLocator    Capacity
BankLabel=0      8192
BankLabel=1      8192

C:\> wmic memphysical get maxcapacity

MaxCapacity    33554432

In this example, the user has 8 RAM slots, 2 RAM modules installed with 8GB capacity each, and the maximum supported RAM capacity is 32GB.

Additional notes:

• These commands work on Windows 10 and 11.
• You need administrator privileges to run these commands.
• Make sure to type the commands accurately, including spaces.
• These commands only provide information about the hardware; they do not show how much RAM is actually being used.

By following these steps, you can easily check the number of RAM slots and maximum RAM capacity of your computer using Command Prompt. This information can be helpful when you want to upgrade your RAM.
