    Win 10 Pro

    6GB of RAM installed but only 4.96 usable

    I installed windows 10 Home 64 bit.
    I have an Acer laptop and I checked the BIOS for any memory options and there's nothing there.

    The BIOS itself, gives me 6144MB of RAM, so I'm guessing everything is fine.
    I checked that the max memory tab in MSCONFIG is unchecked.

    I dont know what to do. I know that Windows doesnt use the whole 6GB but I believe it should be something like 5.XX gb in use.

    Some of it is dedicated to your graphics, it`s called Hardware Reserved, there is nothing wrong, don`t worry about it.

    If you want you can open Task Manager, Performance, Resource Monitor, then click the Memory tab and it will have a bar graph explaining everything.

    Windows 10 Pro x64

    Same issue here on an older Dell Dimension, Win 10 Pro 64-bit, with only 3Gb of 4Gb usable. This machine has a 2Gb add-in video card, so doesn't really need any system memory dedicated to the video. Same reason still?
