Do you want to know how much RAM your PC can take per slot?
Sometimes, along the way we need to upgrade the memory of our computer by adding more memory sticks.
But to avoid buying the wrong memory stick we need to check the model (e.g DDR3, DDR4, DDR5, …), the frequency, and most importantly the maximum size supported by the motherboard.
In this tutorial, we will see how much RAM our system has and how much GBs can we add per slot. Yes you read that right, there is a maximum size per slot per model of motherboard.
Let’s dive in!
Check Maximum Size of Memory Sticks on Windows 10
To know how much RAM your system has, just press WIN+Pause.
Read the information next to “Installed memory (RAM):“.
If you want to see the slots available and the size of RAM per memory stick head to the Task Manager.
You can open the Task Manager from the Taskbar or by pressing Ctrl+Shift+Esc.
Head to the “Performance” tab and check “Memory“.
You will find the Speed and Slots used.
How to Know Maximum RAM We Can Use
Now it’s time to know how much GBs per stick of RAM we can use in our Windows 10 system, this information is related to the motherboard manufacturer if you want to use more RAM than this limit you need to change the motherboard.
First, open the Command Prompt from the Start menu, you can use regular command prompt but I have the habit of using it as administrator.
Type in this command:
wmic memphysical get MaxCapacity, MemoryDevices
I got this output:
MaxCapacity MemoryDevices 67108864 4
Here’s the calculation you will need to do to find the maximum GBs per RAM stick (per slot):
67108864 / 1048576 = 64 / 4 = 16GB
I converted the amount in KB to GB by the first division, then I divided by the number of slots in total to get the maximum amount of GB per slot.
There you have it dear friend
