Windows 10 - Why is my usable RAM only half of my Installed RAM?

Why is Only Half My RAM Usable?

It can be frustrating to see that the PC you spent a lot of money on only uses half the RAM you put on it. There are numerous factors that can cause this issue and, fortunately, they do have fixes.

If you have been experiencing the issue that only half of your RAM is usable, the first fix below might do it for you already.

So, if you’re asking why only half of your RAM is usable, these are the most common causes and the fixes to unleash your RAM to full capacity.

Only Half of RAM is Usable: Causes & Fixes

Windows installation

We’ll start by trying to determine why only half of your RAM is usable on Windows 10.

If you remember how you installed your Windows operating system on your PC, you should know if you have installed the 64-bit or the 32-bit version. To double-check, you can open the systems information application and check your PC’s specifications.

On your Window search bar, type systems information and open it. Once you open it, go to the systems summary tab and you will be able to see a ton of information about your computer. Look for “System Type” and you will see if you are currently running a 32-bit or a 64-bit Windows.

Another way to check is by opening “Dxdiag” from your computer. You can search it on the Windows tab or run the keyword on the Command Prompt. When you open Dxdiag, look for your operating system and it should say something like “Windows 10 Pro 64-bit”.

The reason you are checking this is that if you are running a 32-bit system, your computer can only access 4GB of RAM. The difference between a 32-bit and 64-bit system is immense.

At this point, if you see yourself running a 32-bit system, you have identified the problem right away and the only way to fix it is by reinstalling your operating system (Windows) to a 64-bit installation.

Memory Limitation

Another possible issue would be your computer having a set limitation for the usable memory available on your computer. It has to be manually applied but it does happen that this might be the cause of the problem.

To fix the issue, go to your search bar and open “run”. Type “msconfig” to bring up the system’s configuration settings.

You can also just search system configuration on the Windows search bar and open the application. On system configuration, go to the boot tab and click advanced options.

You will see “Maximum memory” with a check box. Make sure to untick the check box so that your PC can freely use all the memory your PC has at the moment.

Check if your RAM is connected properly

Before you blame your PC for only using half the RAM available, check your RAM physically if it is connected properly on your motherboard’s DIMM slots. Use a trial-and-error if you see that it is properly connected.

This is to check if the RAM is faulty or not. Attach one RAM at a time and boot the PC up.

Open the task manager and check your memory usage. Just open the performance tab and check the memory capacity and usage if it aligns with the RAM you just connected to your PC. Do this for each of your RAM sticks by turning off the computer and reconnecting the other RAM stick after booting.

Generally, you might want to do this option last since you might be able to fix your memory with the other methods especially if you are unfamiliar with building PCs.

Registry Editor

Export your Registry Editor first so you can restore it to the original settings if you do something wrong. This is important because if you make mistakes in deleting or editing other files here, things can go wrong when you use your PC.

Once you open the Registry Editor, look to the left table and find the HKEY_LOCAL_MACHINE folder. Under that, find Systems and then CurrentControlSet (1 word). Find Control under the CurrentControlSet and then Session Manager. Under Session Manager, find the Memory Management folder. This should be the last folder out of this long list of steps.

To sum it up – HKEY_LOCAL_MACHINE > Systems > CurrentControlSet > Control > Session Manager > Memory Management

Inside the Memory Management folder, switch to the right table and find “ClearPageFileAtShutdown”. Once you open it, you will see the value name, value data, and base. Just change the value data from 0 to 1. If it was already set to 1, it is already fine.

Conclusion

It is best to go in order when you follow these steps in fixing your usable RAM.

It can be risky to break open your PC or tweaking the registry. If you have no choice, it is better to take precautions on how to carefully open your PC to check your RAM because all the parts are fragile.

If you absolutely have no idea how to open your PC, it is best to just bring it to a computer store and have it checked for a fee. Most likely, they will be fixing everything for you.

If you have a broken RAM, you can check how many RAM slots you have and also see how to check your RAM type for your current PC build. Both can be done through the task manager and researching your motherboard’s specifications. This is for adding new RAM sticks for your PC build if you really need more memory.

Fix: Windows Update Error Code 0x800f0922

This article will help you to fix Windows Update error code 0x800f0922 received after failure of update installation in Windows 10.

It is often recommended that you install latest available updates in your Windows 10. However, sometimes you may not be able to finish installing updates due to an error code. 0x800f0922 is one of such error code which you may receive with Windows Updates.

FIX 1 – Using Command Prompt

1. Right click Start Button or press W8K + X keys and select Command Prompt (Admin) to open Command Prompt as administrator.

2. In the Command Prompt window, type following command and press Enter key. It will simply fix the counter database.

lodctr /R

If the command execution is successful, you would receive ‘Info: Successfully rebuilt performance counter setting from system backup store’ message.

3. Next, execute the following command to make the counter consistent and resync them with Windows Management Instrumentation (WMI).

winmgmt.exe /RESYNCPERF

 

 Once these command executed successfully, you can try installing the updates again. You’ll no longer receive the error code 0x800f0922 now.

What is the USO Core Worker Process or usocoreworker.exe? Are they viruses?

Starting with Windows 10 version 1903, many users noticed some strange processes running on the system when checking Task Manager such as usocoreworker.exe, usoclient.exe or USO Core Worker Process. So what role do these processes play in the operation of the system or are they malware? Let's find out in this article.

USO Core Worker Process on Windows 10 1903

USO stands for Update Session Orchestrator (a new tool to coordinate and manage update sessions), a new Windows Update Agent.

Previously, on older versions of Windows, you used the wuauclt.exe / detectnow command to schedule a Windows update scan through the Command Prompt, but now you can no longer use this command on 1903. On Windows 10, Windows Update settings are moved from the traditional Windows Control Panel to the new System Settings app. If you've tried managing Windows Updates on Windows 10, Windows Server 2016, and Windows Server 2019 with the wuauclt command, you'll realize that this command no longer works.

From Windows 10 1903, Windows Update uses usoclient.exe, usocoreworker.exe, usoapi.dll, usocoreps.dll and usosvc.dll to scan for updates, install and continue updates. Windows will also call these processes when adding new features to Windows.It is difficult to find details related to usoclient.exe, or usocoreworker.exe in Microsoft documents. Microsoft did not provide any specific information, they just said: This command is not created to call outside the internal operating system (internal OS). No one outside the operating system can run usoclient directly.

In summary, it can be understood that, usocoreworker.exe, usoclient.exe or USO Core Worker Process is a type of system process, related to the management, installation of Windows updates as well as new features of this operating system. It runs in the background.

Thank You!

3) You should then see the Services window again. Double-click Windows Update.

4) Set its startup type to be Disabled and click Stop. Then click Apply > OK.

5) The CPU usage on your computer should return to normal. If it doesn’t you can try Method 2 below.

Method 2: Change your Internet setting

The other way to stop Windows Automatic Update on your computer is to change your Internet to metered connection. See how:

Case 1: You’re using a Wi-Fi Network
Case 2: You’re using an Ethernet Network

Case 1: You’re using a Wi-Fi Network

1) Go to Start > Settings > Network & Internet > Wi-FI. Then click Advanced Options.

2) Tick on Set as metered connection

You’re done. Check if the problem still exists.

Case 2: You’re using an Ethernet Network

1) On your keyboard, press the Windows key and R at the same time to invoke the Run box.

2) Type regedit and click OK.

3) Click Yes when prompted by UAC ( User Account Control ).

4) On the open window, go to
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > NetworkList > DefaultMediaCost
Then Right-click  DefaultMediaCost and select Permissions.

5) Click Add...  Then type your user name into Enter the object names to select and click Check Names.
