Why is only half my ram usable

Why is only half my ram usable. It can be discouraging to discover that the computer you spent a lot of money on is only using half of the RAM you installed. Although there are a variety of reasons that can contribute to this problem, all of them can be remedied.

If you have been experiencing the problem where only half of your RAM is usable, the first repair listed below may already have resolved the problem for you.

For those wondering why only half of your RAM is usable, here are the most common causes and solutions to help you use your RAM to its full potential.

Causes & Solutions for Using Half of Your RAM

Windows installation

Initially, we’ll try to figure out why Windows 10 only uses half of your RAM.

Your PC’s operating system should tell you if it is 64-bit or 32-bit if you remember how you installed it. You can double-check your PC’s specifications by opening the system information application.

Type systems information into the window’s search field and click on the resulting result. To learn more about your computer, click on the “systems summary” tab after it is open. Make sure you check the “System Type” section to determine if you’re currently operating a 32 or 64-bit Windows.

You may also launch “Dxdiag” on your computer to perform the same test. You can use the Windows tab to do a search or the Command Prompt to do a keyword search. In Dxdiag, look for your operating system and you should see “Windows 10 Pro 64-bit.”

This is because if you are using a 32-bit operating system, your computer can only access 4GB of RAM. A 64-bit system is light years ahead of a 32-bit one.

As of this writing, the only option to fix the problem is to reinstall your operating system (Windows) to a 64-bit installation. At this point, you’ve already recognised the problem.

Memory Usage Restrictions

Another possibility is that your machine has a predetermined limit on the amount of usable memory it has. Manual application is required, however it can be the cause of the issue.

To repair the problem, type “run” in the search field and press enter. To access the system’s configuration options, type “msconfig” in the command line.

To access the application, simply type “system configuration” into the Windows search box and click on it. Navigate to the Boot tab and select Advanced Options from the System Configuration menu.

A checkbox labeled “Maximum memory” will be displayed. Your PC should be able to use all the memory it currently has, so make sure you uncheck the box.

Verify that the RAM is correctly connected

Make sure your RAM is physically linked to your motherboard’s DIMM slots before you blame your PC for only using half of the RAM it has available. If you’re confident that everything is linked properly, go ahead and try it out.

The purpose of this test is to determine whether or not the RAM is defective. Boot the computer one piece of RAM at a time.

Take a look at your memory consumption in the task manager. Make sure that the memory capacity and utilization are in line with the RAM you just installed on your computer by opening the performance tab. Turn off the computer and then reconnect the other RAM stick after the computer has restarted.

If you’re not experienced with building PCs, save this option for last because you might be able to fix your memory in another way.

Registry Editor

Before you begin, make a backup of your Registry Editor settings so you have a backup in case something goes wrong. You need to pay attention to this because if you make mistakes in deleting or modifying other files here, your PC may not function properly.

To discover the HKEY_LOCAL_MACHINE folder, look to the left table in the Registry Editor. To go to CurrentControlSet, go to Systems and then (1 word). Session Manager can be found under Control in the CurrentControlSet. Memory Management is located in Session Manager. This extensive list of actions should end with the creation of this folder.

HKEY_LOCAL_MACHINE > SYSTEM > CURRENT CONTROL SETTINGS > CONTROL > Session Manager > Memory Management is where you’ll find all of this information.

Go to the right table in the Memory Management folder and look for “ClearPageFileAtShutdown.” Value name, value data, and base are all displayed when you open the value. All that needs to be changed is the digit value from 0 to 1. A setting of 1 indicates that everything is fine.

Conclusion

Follow these steps to restore your usable RAM in the correct sequence.

The act of disassembling your computer or tinkering with the registry can be dangerous. For this reason, it’s best to take measures when opening your PC to inspect your RAM because all of the components are delicate.

A computer retailer can perform an open-system check for you for a cost if you don’t know how to open your PC. They’re almost certainly going to take care of everything for you.

If your RAM is corrupted, you can discover how many RAM slots you have and what sort of RAM you have installed in your PC by following the steps outlined below. Researching your motherboard’s specifications can also be used to accomplish this. If you need to expand your PC’s RAM capacity, this is the place to go.
