How to Change the Size of Shared System Memory in Windows 10

Shared system memory is an important resource in Windows 10 that allows the operating system and applications to efficiently share and utilize memory. By default, Windows 10 automatically manages the size of shared system memory based on the system's needs. However, in some cases, you may want to manually change the size of shared system memory to optimize performance or troubleshoot issues.

In this article, we will guide you through the process of changing the size of shared system memory in Windows 10. Please note that modifying this setting requires administrative privileges, so make sure you have the necessary permissions before proceeding.

Step 1: Open the System Configuration Utility

The first step is to open the System Configuration utility, also known as "msconfig." To do this, follow these steps:

1. Press the Windows key on your keyboard to open the Start menu.
2. Type "msconfig" (without quotes) in the search bar.
3. Click on the "System Configuration" app that appears in the search results.

Step 2: Access the Boot Configuration Data (BCD) settings

Once the System Configuration utility is open, navigate to the "Boot" tab. Here, you will find the Boot Configuration Data (BCD) settings.

Step 3: Modify the shared system memory size

In the Boot Configuration Data (BCD) settings, click on the "Advanced options" button. This will open a new window with additional advanced settings.

Look for the "Maximum memory" option and check the box next to it. This will enable you to manually set the size of shared system memory.

Enter the desired size of shared system memory in megabytes (MB) in the text box provided. It is recommended to consult your system's documentation or manufacturer's website for the optimal size of shared system memory for your specific hardware configuration.

Once you have entered the desired size, click on the "OK" button to save the changes.

Step 4: Restart your computer

After modifying the shared system memory size, you need to restart your computer for the changes to take effect. Make sure to save any unsaved work and close all open applications before proceeding.

Click on the "OK" button in the System Configuration utility to close it.

Press the Windows key on your keyboard to open the Start menu.

Click on the power icon and select "Restart" from the options.

Step 5: Verify the changes

Once your computer restarts, you can verify if the changes to the shared system memory size have been applied successfully. To do this, follow these steps:

1. Press the Windows key + R on your keyboard to open the Run dialog box.
2. Type "msinfo32" (without quotes) in the Run dialog box and press Enter.
3. In the System Information window, navigate to the "System Summary" section.
4. Look for the "Installed Physical Memory (RAM)" field. The value displayed here should match the size you specified for shared system memory.

If the displayed value matches the size you set, it means that the changes have been applied successfully.

Congratulations! You have successfully changed the size of shared system memory in Windows 10. Remember that modifying this setting should be done with caution and only if necessary. If you experience any issues or instability after changing the shared system memory size, it is recommended to revert back to the default settings or consult with a technical expert.
