I agree. There should not be nearly that much stuck in Hardware Reserved. Sorry, but mapping does not work that way. I have just 42MB in Hardware Reserved
and my graphics card has 4GB of GDRR5.

I have 32GB installed, and as can be seen, with 7.2GB in use, I still have 25.4 available.
When excessive Hardware Reserved is seen, as satrow noted, it typically means you have a faulty hardware driver. You might try booting into Safe Mode and see what happens. To enter Safe Mode in Windows 10, go to Settings > Update & Security > Recovery > Advanced startup, click Restart now. After PC restarts, in Choose an option menu, select Troubleshoot > Advanced options > Startup Settings > Reset. After second restart, in Startup Settings menu, select Enable Safe Mode (usually #4) to restart a third time into Safe Mode. See

And/or you might disconnect all extra hardware and leave just your boot drive, keyboard and mouse and see where you are.
