How To See How Many Memory Slots Are Used

7/10/2022

On my laptop, command line probes say I have 4 slots (2 used, 2 empty), yet upon unscrewing I actually have 2 slots (perhaps I have 2 hidden slots elsewhere yet not visible removing bottom panel). How do you see how much RAM is in your computer? You can easily check the details of RAM in Windows 10 using the Task Manager. The task manager performance tab shows a majority of memory details including the total amount of RAM, how much is in use, committed/cached and paged/non-paged amount of RAM, RAM speed and frequency, form factor, hardware reserved and even how many slots are being used. Although you can open your computer case or check your documentation to verify the total RAM slots, you can also confirm the total number of slots supported on your motherboard via Task Manager.

When a user wants to add or upgrade memory (RAM) in a computer, they need to know how many memory slots are available. The following section helps you to determine the number of memory slots in your computer, and how many are used.

Examine the motherboard

Sometimes the best way to determine the available memory slots is to open the computer and examine the motherboard. Opening the computer is the best option if were unable to get the Windows Task Manager or CPU-Z to work.

Looking inside the case, the motherboard is the primary large circuit board. On most motherboards, the memory slots are on either side of the CPU, and resemble what is shown below.

Most computer motherboards have two, three, or four memory slots. Some higher-end motherboards have as many as eight. The above motherboard picture above has no memory modules installed in any of its three slots.
