Why Your Installed RAM May Not Show Up On Windows!

Upgrading our PC is an ever-ongoing process. One of the easiest ways to make our PC faster is by upgrading the RAM.

But upgrading RAM doesn’t mean Windows will also register it.

It may sound odd, but installing RAM isn’t as simple as placing your newly bought RAM stick in its slot, even if you bought the correct supported RAM.

There are various factors that one must take account of before upgrading their RAM. Otherwise, you will find your installed RAM not showing up.

Here I have discussed all the details on why your RAM may not show up on your Windows and how you can fix it.

We have shown a VIDEO walk through at the end of the post for easy solution.

RAM Not Showing Up On Windows

When you buy a RAM, the first thing is to make sure it is supported on your system.

Now, assuming you have done that and still the installed RAM is not showing up on your system, follow the methods I have given here to solve it.

1) Are You Using 32-Bit Windows?

One of the most glaring mistakes many users make is not checking their Windows architecture before upgrading their RAM.

Windows versions come in two architecture, 32-bit and 64-bit.

If you are using a 32 bit Windows, then your system will only register 4 GBs of RAM. Even when you have more installed.

How to check it? Type About Your PC in the search bar and select the top result. On the window that appears, check the System type under the Device Specifications.

So, what’s the solution? You will have to install Windows 64-bit to have more RAM registered on your system.

2) Check If RAM Exceeds Windows Physical Memory Limit

Other than the Windows system architect, Windows versions also have limits for RAMs.

For example, Windows 7 Home basic 64 bit users have a limit of 8 GB RAM. Anything more will not get registered by the system.

Check if the physical memory limit of your Windows version. Visit here to learn the memory limits for Windows and Windows server.


3) Check If Memory Is Limited In Windows System Configuration

Memory on Windows can be limited by changing certain settings in the System Configuration.

You may have done this by mistake or someone else may have done this on your PC. Here is how you can check whether this is the case:

  • Press the Windows + R keys to open Run utility. Type msconfig in the command box and press Enter.


  • Click on the Boot tab in the System Configuration window and select Advanced Options.


  • See if the Maximum memory box is checked. If yes, uncheck it.


  • Click on OK and then Apply and OK to save the changes. Restart your PC to boot with the entirety of your installed RAM.

4) Check If Integrated Graphics Is Utilizing The Missing RAM

Does your system have integrated graphics and not a dedicated graphics card? Integrated graphics will allocate a certain amount of memory for usage.

Dedicated graphics cards come with inbuilt RAM for its work. That’s not the same for integrated graphics, which is why it uses your system’s RAM.

Type About Your PC in the search bar and select the top result. In the window that opens, check the Installed RAM in Device specifications.

If your PC has integrated graphics, it should show the installed RAM correctly while mentioning the usable portion beside it.integrated_graphics_using_memoryThe portion of memory missing is being used by the integrated graphics of your system.

The only thing you can do here is get a dedicated graphics card and uninstall the integrated graphics drivers.

5) Motherboard Limiting Installed RAM

One of the important things to check before buying RAM is to make sure it stays in the motherboards limit. Motherboards have RAM size limits.

If you install more RAM than supported by your motherboard, it won’t show up.

So, when your computer is not recognizing RAM, it may be that your motherboard doesn’t support the size you have installed.

The easiest way to check this is by entering BIOS and checking the system information for recognized RAM sticks.

If BIOS recognizes RAM but Windows does not, then the issue lies with Windows.

If it does not register all the RAM sticks, then the first thing you must check is your motherboards RAM limit.

You can check this by visiting the motherboard’s manufacturer. If the motherboard does support the installed RAM, then follow last few methods mentioned below.

6) Check If RAM Is Seated Properly

If the RAM doesn’t register in your BIOS, and your motherboard should support it, then it may not be seated properly.

Try reseating your RAM and check if still installed RAM is not available on your PC.

Also, if you have free channels left, try seating RAM on another channel than it was previously on.


Make sure that the RAM is properly seated and clip it from both sides. If reseating also doesn’t work, see the next solution.

7) Defective RAM

If none of the above solutions could make your installed RAM appear on the system, it is likely that the RAM stick is defective.

One of the easiest ways to check this is seating the RAM in another PC (that should support it) and check if it works.

If it also fails to work on the other PC, then the RAM is likely faulty and you will have to buy a new one.
