    Exclamation [CentOS] RAM upgrade not used


    BISMILLAHIRRAHMANIRRAHEEM
    Hi,
    I'm using CentOS 7 on vmware. I reserved the RAM from 2 GB to 4GB in vmware settings. CentOS shows 4 GB RAM in system monitor and free -m command, however, system monitor shows that only 1.9 GiB of 3.7GiB (51.7%) of RAM is being used. It is using ~450MiB for swap.

    swappiness is 30.

    vmware has also reserved 4GB RAM in Windows 7. I have 8GB installed.

    There is no /boot/grub/grub.conf

    How do I get CentOS to use full RAM?

    Edit: It recently started using 2.1GiB (57%), but still there's more free.
