How to Troubleshoot ‘Windows 10 won’t Use Full RAM’ Problem

Random Access Memory (RAM) is a non-volatile storage device that is typically used to store working data and machine code. When you turn off your computer, all data in it is lost because it is temporary memory. The more memory your computer has, the more smoothly it can multitask.

However, you may run into a problem with Windows 10. In the system properties or in the Task Manager, you may find that Windows is only using a fraction of the total amount of RAM.

What is the reason why Windows 10 is not using all the RAM?

  • It may be because the RAM module is not inserted correctly. If you recently installed a new RAM, you may not have fixed it properly, which is what is causing this problem.
  • Your RAM may be faulty. In most cases, faulty RAM causes the “blue screen of death” to appear. So, if your computer restarts frequently, it is possible that your RAM is faulty.
  • If Windows 10 is not using all the RAM, it may be because the RAM modules are not installed in the right order. Many motherboards are quite specific about the order of the RAM modules.
  • Sometimes Windows 10 doesn’t use all of your RAM because it doesn’t match your motherboard. In this case, it is not recognized by your computer and cannot be used.
  • If Windows 10 is not using all of your RAM, it may be because your BIOS is not up to date. It is likely that your memory is not compatible with your motherboard.
  • According to users, this problem was caused by a modified BIOS. Some users report that Windows 10 doesn’t use all the memory because they have a modified version of the BIOS.
  • Windows 10 often doesn’t use all of the working memory because the integrated graphics aren’t working. The integrated graphics card is built into the motherboard and uses a certain amount of RAM.

How to solve the problem when Windows 10 doesn’t use all of the working memory?

Enable the “Memory Reallocation” feature

Enabling the “Memory Reallocation” feature seems to solve the problem of Windows 10 not using all of the RAM.

  1. Reboot your computer and press F2, DEL, or F12 (depending on the manufacturer) at the same time when you turn it on to access the BIOS settings.
  2. Go to the Advanced Chipset Features section.
  3. Then under North Bridge Configuration or Memory Feature, locate Memory Remap Feature.
  4. Set Memory Remap Feature to Enable.
  5. Save and complete the changes and reboot the computer as normal.

Disable the Maximum Memory Remap option

  1. Press Windows + R, type MSConfig, and press Enter to open System Configuration.
  2. Go to the Boot tab and make sure you highlight the currently installed operating system.
  3. Then click on Advanced Settings, uncheck the Maximum Memory checkbox, and click OK.
  4. Now click Apply, then OK, and close everything. Restart your computer to save your changes.

Launch Windows memory diagnostics

  1. Type memory in the Windows search bar and select “Windows Memory Diagnostics”.
  2. From the options that appear, select “Restart now and check for problems”.
  3. This will restart Windows to check for RAM errors and hopefully show possible reasons why Windows 10 is not using all of its memory.
  4. Reboot your computer to save your changes.

  6. Monitor your memory and clean up your processes.
  7. Disable unnecessary startup programs.
  8. Stop applications running in the background.

The problem may be caused by incorrect BIOS settings. Check your BIOS settings to see if memory reallocation is enabled. Memory reallocation allows Windows to access more memory. You can enable the memory reallocation feature in the BIOS by going into System Setup.

Find and click the Settings or Hardware menu. Check the amount of RAM specified in your computer's BIOS. Make sure that the amount of RAM matches your recent update. Click the appropriate button to save your BIOS settings and exit the computer.
