Adjust BIOS Settings to Reduce Hardware Reserved Memory

One of the primary reasons for excessive hardware reserved memory in Windows 10 is how the BIOS allocates system resources. The BIOS may reserve memory for integrated graphics or other hardware components, which decreases the amount of RAM available to the operating system. Adjusting BIOS settings can help reduce hardware reserved memory.

Access your computer’s BIOS or UEFI firmware settings by restarting and pressing the appropriate key (often F2, Delete, or Esc) during boot. Once inside the BIOS menu, consider the following changes:

  • Disable Integrated Graphics if you use a dedicated GPU. This frees up memory reserved for onboard graphics.
  • Adjust Memory Remapping Feature: Ensure that “Memory Remapping” or “Memory Hole Remapping” is enabled to allow the OS to access all installed RAM.
  • Disable Unused Hardware: Turn off devices or peripherals that are not in use, such as serial ports or onboard sound cards, which might reserve memory.
  • Update BIOS Firmware: Sometimes, outdated BIOS versions have bugs causing improper memory allocation. Updating to the latest BIOS version can fix this.

After making changes, save and exit the BIOS setup to reboot the system and check if the hardware reserved memory has decreased.

Modify Windows Memory Settings via System Configuration

Windows 10 allows users to configure the maximum memory available to the system through the System Configuration utility (msconfig). Incorrect settings here might limit usable RAM and increase hardware reserved memory.

To verify and modify these settings:

  • Press Win + R, type `msconfig`, and press Enter.
  • Navigate to the Boot tab and click on Advanced options.
  • Ensure the Maximum memory checkbox is unchecked. If it is checked, Windows restricts available RAM to the specified value, which can cause increased hardware reserved memory.
  • Click OK, then Apply, and restart your computer.

This step ensures Windows can access the full range of installed memory without artificial limitations.

Disable Memory Remapping Conflicts in Device Manager

Hardware reserved memory can sometimes be caused by conflicts between device drivers and memory mapping. Windows allocates memory addresses to hardware devices, and improper mappings can cause excessive reservation.

To identify and resolve such conflicts:

  • Open Device Manager (press Win + X and select Device Manager).
  • Expand categories such as System devices and look for devices with a yellow exclamation mark indicating conflicts.
  • Right-click problematic devices and select Update driver to ensure the latest drivers are installed.
  • If updating does not resolve the issue, try disabling and re-enabling the device or uninstalling and reinstalling the driver.

Additionally, check the Resources by connection view in Device Manager to see how memory is assigned to hardware and identify any overlaps or conflicts.

Use Command Line Tools to Check Memory Usage

Windows provides tools to inspect memory allocation in detail, which can help diagnose hardware reserved memory issues.

  • Open **Command Prompt** as administrator.
  • Run the command `systeminfo` to view installed and available physical memory.
  • Use `wmic MEMORYCHIP get BankLabel, Capacity, DeviceLocator, MemoryType, TypeDetail, Speed` to list details about installed RAM modules.
  • Run `msinfo32` to open the System Information window, and navigate to **System Summary > Installed Physical Memory (RAM) and Hardware Reserved** to compare values.

These tools provide insight into how much memory is installed, reserved, and usable, helping pinpoint the cause of memory reservation.

Optimize Paging File Settings for Memory Management

The paging file (virtual memory) settings influence how Windows manages RAM and hardware reserved memory. Although the paging file does not directly reduce hardware reserved memory, improper configuration can exacerbate memory issues.

To optimize paging file settings:

  • Right-click This PC and select Properties.
  • Click Advanced system settings, then the Advanced tab.
  • Under Performance, click Settings, then the Advanced tab.
  • Click Change under Virtual memory.
  • Ensure that Automatically manage paging file size for all drives is enabled, or manually set a paging file size recommended for your system.
  • Avoid setting the paging file to zero or excessively low values, which can cause memory management problems.

Proper paging file management ensures efficient use of available memory resources.
