6GB of RAM installed but only 4.96 usable

BDani · 28 Oct 2016

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.

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?
