Hardware reserved memory issue

memorywindows 7

I've seen lots of folks having problem with hardware reserved memory issue in Windows 7/Server 2008 R2. I have it myself but not as huge as others have.

Problem description

When you install Windows 7 (or its bigger brother Windows Server 2008 R2) your memory may not be fully utilised. If you look at

Task Manager >
    Performance Tab >
        Resource Monitor >
            Memory Tab

And scroll to the bottom of the list you will see a graphical representation of your memory. Some of it may be hardware reserved. Previous Windows versions didn't have this problem. System was able to utilise all memory available.

Question

Is there any solution to lower/remove hardware reserved memory?

Sidenote

I tried installing 32 and 64 bit versions but to no avail. I also tried both Windows: 7 and Server 2008 R2. But always get the same amount reserved by HW. On previous Windows versions I had more memory available because I'm simultaneously running 2 VMs on host (so three machines all together). And my memory peaks much higher now as it did on older versions.

Best Answer

Your PC always consumed that RAM, but older versions of Windows didn't show.

Now if you think that the hardware reserverd memory is a lot we need to which device is consuming that and how much each device.

For do that open the Device Manager (devmgmt.msc), go to the view menu, Select Resources By Connection and expand the Memory subtree. There you have the ranges of RAM used by each device.

Convert the two values of each device from hexadeximal to decimal, and substrac them. The difference is how much memory is a device using. This way we will know what are taking you RAM.
