Windows 10: Hardware-reserved memory is just too much!

Hey Microsoft.

I've got an HP Compaq 6005 Pro Microtower PC with 8GB of RAM installed. Previously it used to show that 7.50 GB memory was usable. Now, however, it displays only 3.50 GB usable, which means that more than half of the memory is being wasted. Kindly give suggestions to solve this, if any! Oh yeah, I forgot to mention, the RAM is DDR3.

Thanks!

Hardware reserved memory

Got that Nikola. The error you are getting which is the "hardware reserved" is almost related to BIOS. Since the previous steps did not work, let us check if the steps below will make any difference on the issue:

1. Delete some files that you are no longer using.

2. Re-instate the old BIOS. If it is still not working, install the newer BIOS instead.

3. Check possible issues with the physical RAM. Check whether you have bad memory modules and if standoff cards are used. Make sure that the memory arrangement is correct.

Let us know if there's any changes.

Thank you.

 

System Reserved Memory issue

Hi Rowan,

The reduction in available system memory depends on the configuration of the following:

• The devices that are installed in the computer and the memory that is reserved by those devices
• The ability of the motherboard to handle memory
• The system BIOS version and settings
• The version of Windows 10 that is installed
• Other system settings

As an initial troubleshooting step, I suggest that you check your system for memory problems.

Here's how:

• Type mdsched.exe in the search bar and select the best match.
• When prompted by the User Account Control, enter an admin user name and password, and click
  Yes.
• Follow the on-screen instructions to run it.

Let us know how it goes.

 

How to reduce Hardware Reserved Memory in Windows 10 Pro

Hi Lmo,

You cannot release or use full of hardware reserved memory. The amount of usable memory in the examples are not exact amounts. Usable memory is a calculated amount of the total physical memory minus "hardware reserved" memory. Memory that is reserved
for use by the BIOS and some drivers for other peripherals. The reduction in available system memory depends on the configuration of the following:

• 
  The devices that are installed in the computer and the memory that is reserved by those devices.
  
• 
  The ability of the motherboard to handle memory.
  
• 
  The System BIOS version and settings.
