Windows 10: Reserved hardware ram fix

I have a Lenovo Legion Slim 5 with 16GB of installed RAM, but 2.3GB is reserved for hardware. I want to fix this issue. I checked the BIOS, and the UMA buffer is set to 512MB. Why is the reserved memory so high, and how can I reduce it?

Half of RAM 'Hardware Reserved'

I have 32GB of RAM installed and half is "hardware reserved" by Windows. I've tried every suggestion I can find, including moving the modules around to different slots. My MB does not have onboard graphics. Specs:

• Motherboard: Gigabyte GA-AX370M-DS3H (BIOS on latest firmware)
• CPU: Ryzen 7 2700X (upgraded from 1700x and it didn't help)
• RAM: Corsair VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 2400MHz C16 Memory Kit
• GPU: Nvidia RTX-2060 Super

The BIOS, Windows, CPUZ and HWInfo all show 32GB installed and both slots used, but Windows says "Hardware Reserved: 16.1GB". This was occurring on Windows 10. I am currently running Windows 11 (beta channel) and it didn't help. I also upgraded my CPU from a Ryzen 7 1700 with no change. Pics: Imgur: The magic of the Internet

Hi John,

Thank you for posting in Microsoft Community.

I understand that you would like to uncheck/change the hardware reserved memory size.

I would like to let you know that Hardware reserved memory is reserved for use by the BIOS and some drivers for other peripherals. I would suggest you to not make any changes to this. This will help the computer run smoothly.

If you are facing any problem with the hardware reserved memory, please post back with the issue. We’ll be glad to check and help you accordingly.

Thank you.
