Computer not using all RAM? How to increase usable RAM

If necessary, you can also check and make sure that the locks correctly maintain your RAM memory. Please note that you must be very careful when handling the device in order not to damage the PC.

If you don’t know how to check your RAM, it’s best to consult an expert.

4. Check if your RAM is damaged.

If Windows 10 does not use all of your memory, your memory may be faulty. In most cases a defective RAM causes a blue-screen error. For example, if you regularly reboot your PC, your RAM may be faulty.

The easiest way to test your memory is to check your modules one by one. Just remove everything but one module and see if your PC recognizes all the RAM. Repeat these steps for all memory modules until you find the defective module.

If you want to perform a detailed analysis, it is highly recommended to analyze each RAM module with the MemTest86+ tool. This is a free tool that allows you to perform a detailed scan of your RAM.

Just make a USB stick bootable with MemTest86+ and boot your PC from this USB stick. Then start the scan and let it run for a few hours. Note that you will need to analyze each RAM module separately, which may take some time.

Once you have found the problematic module, remove it and replace it with a new one. Several users have reported that this error occurred on their computer due to a RAM error, so check the RAM.

5. Reconnecting the RAM modules

If users say that Windows 10 does not use all of their RAM, your RAM modules may have been installed in the wrong order.

Many motherboards are quite specific about the order of the RAM modules, so it may be necessary to remove and reorganize the RAM to solve this problem.

We also recommend that you refer to the motherboard manual for instructions on how to install the RAM modules correctly.

If you are using two modules, do not forget to plug them into their respective sockets. Their plugs are of different colors. If you are using two modules, make sure that you insert them into the sockets with the corresponding colours.

Users have reported that rearranging RAM has solved the problem, so feel free to try it.

6. Changing BIOS settings

If Windows 10 does not use all your memory, this can usually be due to the BIOS settings. To solve the problem, you need to go into the BIOS and change some settings. Refer to your motherboard’s manual for information on accessing the BIOS.

After entering the BIOS, the following settings have to be changed:

  • Vitualization – ON.
  • IGPU – OFF.
  • Lender stability – including
  • iGPU memory – Auto
  • Multimonitor – Disabled people

The Memory Remap function must also be activated. To do so, go to Advanced > System Agent Configuration > Memory Recast and set it to Enabled.

Then save the changes and solve the RAM problem. If the BIOS has internal or built-in graphics options, make sure they are disabled.

Several users have reported that the only way to solve this problem is to change the iGPU settings in the BIOS, so give it a try.

If you would like to know more about these settings and how to access them, we strongly recommend that you consult your motherboard’s manual.

Also note that changing the position of the frame buffer from more than 4G to less than 4G may solve the problem, so you might want to try that.

7. use mconfiguration

  1. Press Windows + R and type msconfig. Press Enter or OK.
  2. The system configuration window then appears. Click on the Boot tab and then click on the Advanced Options button.
  3. Select the Maximum memory size check box and enter the amount available in megabytes. 1Gb is 1024Mb, and since we have 4Gb of RAM on our computer, that’s 4096Mb. Make sure you enter the correct amount of memory in megabytes for your PC. When you’re done, click OK.
  4. Save the changes and restart the computer.

Some users recommend repeating the steps in Solution 1 and disabling the swap file after setting the maximum memory size, so you can try this too.

It should also be noted that many users have been able to solve this problem simply by disabling the Maximum Memory option. If this option is enabled in Windows, make sure it is disabled and see if this solves the problem.

8. Change of registration

  1. Press Windows + R and type regedit. Press Enter or OK.
  2. Not necessarily: Changing the registry can be dangerous, so it is advisable to make a backup copy before making any changes. To save the registry, click File > Export.
    Now select All as the export range and enter the desired file name. Choose a safe place and click Save.
    If you experience problems after changing the registry, you can easily restore the original state by running the file you just created.
  3. In the left window, go to the next button: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerStorage management
  4. Double-click the DISPLAY FILE WORD in the right window to open the properties.
  5. Set the value to 1 and press OK.
  6. Not necessarily: Many users say that the DWORD ClearPageFileAtShutdown value data should be set to 2 and the changes saved. Then set the same DWORD data value to 0 and save the changes.

After making the necessary changes, turn off the computer and see if the problem persists.

You don’t have access to the registry editor? Read this guide and solve the problem quickly.

9. Check RAM compatibility with themotherboard .

Sometimes Windows 10 does not use all RAM memory because it is not compatible with the motherboard. In this case it is not recognized by the computer and you cannot use it.

To solve this problem, please refer to your motherboard’s manual and check if your current memory modules are supported.

Some RAM models are not fully compatible with some motherboards and you will need to replace the RAM with a compatible model to solve this problem.

10. BIOS Update

If Windows 10 does not use all your memory, your BIOS may be outdated. Chances are that your memory is not compatible with your motherboard, and by updating the BIOS you can solve the problem.

BIOS updates offer new features and better hardware compatibility, so a BIOS update may be the solution for you.

We have to warn you that the BIOS upgrade is a complicated process that, if you don’t do it correctly, could cause your motherboard to stop working.

To update the BIOS, carefully follow the instructions in your motherboard manual to avoid damage to your PC.

BIOS update is not a risk-free process and is carried out at your own risk.

Several users reported that the problem was resolved after a BIOS update, so consider updating the BIOS.

With this handy guide, updating your BIOS is like a walk in the park!

11. Make sure you use the officialBIOS.

According to users, this problem was caused by a modified BIOS. Some users reported that Windows 10 did not use all their memory because they had a modified version of the BIOS.

However, they managed to solve the problem by flashing their BIOS and using the official version instead.

Modified versions of the BIOS may not be safe to use. Therefore, always use the official BIOS if you want to avoid problems.

12. Make sure you have integrated the illustrations.

Windows 10 often doesn’t use all the memory because of the built-in graphics. Built-in images are built into the motherboard and use a certain amount of RAM.

Dedicated graphics cards on the other hand have their own memory, so they do not use the memory of your system. To check if you have a built-in graphics card, all you have to do is check your motherboard information.

You can also check the connections to your computer box. If you have a VGA, DVI or HDMI connection in addition to other connections on your motherboard, you probably have integrated graphics.

To disable the use of embedded graphics in RAM, you need to install a special graphics card and disable embedded graphics in the BIOS.

For instructions on how to do this, please refer to your motherboard’s manual for detailed instructions.

Check the graphics card information like a real technician with these tools!

13. Make sure the BIOS recognizes your RAM.

If Windows 10 does not use all of your RAM, you may have exceeded your RAM limit.

All motherboards have a certain limit on the amount of RAM they can support. If you have an older motherboard, you may have exceeded the maximum amount of RAM the motherboard can use.

To find out how much memory your motherboard can support, please refer to your motherboard’s user manual.

In addition, it is recommended to check the system information in the BIOS. If the BIOS indicates the correct amount of RAM, it means that your motherboard can recognize and support it.

This means that the problem is caused by Windows and not your hardware.

Windows 10 does not use all your memory, which can be a big problem because it can significantly reduce your performance.
