Is your PC sluggish? You might want to consider adding more memory (if you’ve got spare RAM slots). You can check this information using these steps.

Thinking about upgrading your system RAM? You’ll need to know how many memory slots you have available.

If you’re running Windows 11, you can find your available memory slots in a few different ways. Whether you can upgrade them or not will depend on your device. Laptops are typically harder to upgrade, but desktop PCs are fairly straightforward.

If you want to know how to find the number of available memory slots on Windows 11, follow the steps below.

If you need to check to see the amount of available memory slots on your Windows 11 PC, use the following steps.

1. Right-click the Start button and select Task Manager from the menu.
2. When Task Manager opens, click the Performance tab at the top.
3. Select Memory on the left.
4. You can find the number of slots next to the Slots used option at the bottom-right of the window. In this example, our PC has two slots and both are being used.

How to Check Available Memory Slots with PowerShell

Another built-in tool you can use to determine the number of available RAM slots is to use PowerShell. This is a good option for users who enjoy using the command line. You can also use the newer Windows Terminal for these commands. However, the older command prompt won’t work here.

1. Open the Start menu.
2. Search for PowerShell and select the Run as Administrator option on the right.
3. Once PowerShell opens, enter the following command:

   Get-WmiObject -Class "Win32_PhysicalMemoryArray"

   

4. After running the command, you can see the number of slots available on the motherboard.
5. To determine the number of used slots, enter the following command in PowerShell:

   Get-WmiObject -Class "Win32_PhysicalMemory" | Format-Table BankLabel

   

6. After running the command, you can see the used slots to confirm the number of memory sticks installed.
