    Why 2.66 GB usable in 4 GB ram?

    Thanks to everyone for their valuable suggestions. I guess the problem was with the OS.Because after increasing my ram from 4 gb to 8 gb still the usable memory was 2267 mb out of 8 gb, then I did a clean install of Windows 7.Now everything is fine and smooth, and usable memory is 7.9 gb out of 8 gb.

    8 GB RAM installed but only 3.23 GB usable


    I have recently upgraded to Windows 10 Home from Windows 7 Home. And I replaced my 4 RAM sticks with 8 GB RAM but my system shows : Installed memory (RAM): 8.00 GB (3.23 GB usable). Please advise if anyone knows how to fix this.

    Why is it only 3 GB usable?

    My laptop has 12 GBs of RAM installed, but it said that only 2.41 GBs of RAM is usable. How do i change this.

    Done. It didn't detect any problem but then it still says that that only 2.41 Gigabytes are usable. Im even adding a photo showing the problem. Take a look at the Installed RAM.
