Usable RAM Limited by Windows

First things first, we’re going to check some obvious reasons why your RAM is limited on Windows.

Here is a table with the maximum RAM supported by each version of Windows, if your Windows version is one of these and you have the usable memory issue then you need to upgrade to a 64-bit version of Windows.

Version Limit in 32-bit Windows Limit in 64-bit Windows
Windows 7 Ultimate 4 GB 192 GB
Windows 7 Enterprise 4 GB 192 GB
Windows 7 Professional 4 GB 192 GB
Windows 7 Home Premium 4 GB 16 GB
Windows 7 Home Basic 4 GB 8 GB
Windows 7 Starter 2 GB 2 GB

Loose RAM? Check your hardware!

The second thing to check is if you have your RAM stick not inserted correctly, open your PC and check if the connections are alright!

How to Fix Usable Memory in Msconfig

Go to “Boot” tab and click on “Advanced options…

Uncheck “Maximum memory” and click “OK“, restart your PC.

One of the best solutions you can try is to flash your BIOS using a firmware that you can download from the constructor’s website.

Make sure you have the feature “Memory Remap” enabled in your BIOS.

You can access the BIOS using one of these keys when the PC is booting: Esc, F2, F10, F12, Del.
