Hardware reserved memory issue

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.

My problem solved as follow:

Windows 7 SP1 64-bit, Fujitsu NB, 4GB dual channel DDR3 1 bar samsung, 1 bar kingmax, Windows see them, 2050MB hardware

reserved, all solutions found online couldn't solve it.

I tested boot with 1 bar at a time, the samsung bar good ==> 2GB installed, 2MB hardware reserved only ! while the kingmax bar couldn't boot at all !

2 bars of samsung ram, ==> 4GB installed, <2MB hardware reserved only !

Checked with "resmon.exe" of Windows 7 !

Conclusion: Windows 7 may find little problem with the RAM, therefore marked

it as hardware reserved !

Suggestion: Try to set your ram to run at same speed, use same brand of ram.
