How Much Ram Can My Computer Take?

The amount of RAM (Random Access Memory) that your computer can take will depend on each computer. The motherboard and the operating system will be the two things that affect your PC’s total RAM capacity. When you are upgrading or installing your RAM it is very important to understand your PC’s maximum RAM capacity. Going over this limit would be a waste as your PC would not utilize the extra memory. Believe it or not, this is something that many people forget to consider. Every single computer has a maximum allowance varying significantly. Depending on your computer you may even be at the maximum amount already. Checking how much RAM your computer can take is quite easy to do. In all honesty, it can be done in under a minute at most.

Max RAM on Operating System

Depending on which operating system your PC has your RAM capacity may be limited. Within Windows, you first want to identify which type of OS you are using. Thankfully, Windows makes this quite easy to do. If you are running a 32-bit operating system your RAM capacity will be significantly less than a 64-bit operating system.

With a 32 bit OS, you will be limited to 4 GB of RAM for all versions of Windows. However, if your system is running 64 GB it can support up to 128 GB of RAM under Windows 10 Home. If you have Windows 10 Education, Enterprise, or Pro, it can support up to 2TB.

How Do I Check Max Ram Capacity?

The windows command prompt is a super easy and efficient way to check your computer’s RAM capacity. We are also able to check how many memory slots your computer has to use.

1. Press the Windows key + R or search for “Command Prompt” in the Windows search tool

2. Type in “cmd” on the tool that opens up and press Enter. If you searched for “Command Prompt” in the Windows search tool you can skip this step

3. Type in “wmic memphysical get MaxCapacity, MemoryDevices” followed by Enter

There will be two important pieces of information displayed on the screen. First, it will tell you your system’s maximum RAM capacity displayed in kilobytes. We will have to convert this to GB in order to understand it better. All you have to do is take that value and divide it by 1048576 to get GB.

For example, 33554432 kilobytes / 1048576 = 32 GB

The second piece of useful information is the “MemoryDevices”. This will tell you the amount of RAM slots your computer has. If it reads a value of 2, it is stating that your motherboard has two RAM slots.

This is important to remember as you don’t want to use any RAM sticks over these limits. So for example, if your system has a max capacity of 32 GB, with two RAM slots, your capacity per slot would be 16GB.

If you are looking to check your RAM speed, you will have to use different software.

Motherboard Support

Depending on the model of your motherboard you may be left with a different amount of memory slots. Generally speaking, most motherboards come equipped with either two or four slots available. If you have a desktop computer this is quite easy to see as all you have to do is look at the motherboard.

However, it is worth mentioning that even though your motherboard may have a large number of available memory slots. They do still sometimes have a limit as to how much RAM they can use. To find this information out all you need to do is a quick search on the motherboards model. From here you will be able to identify the maximum capacity that it will support.


Once you have been able to find out how much RAM your computer can take you can continue on to upgrading it. Again you want to make sure that your computer has the ability to handle the increase of RAM. Going over this limit would not impact your system in any negative way. But, it would not use anything over this threshold.

Depending on how old your PC is this might be frustrating. Typically older computers have a significantly lower limit making it hard to upgrade. On the other hand, if you have a relatively new PC you should not have to worry about this too much. On newer computers, the limit is quite higher than it used to be. Generally, new PC’s will come equipped with the capability to support up to 32 GB’s at a minimum.
