    Just did a new build yesterday with a ryzen 2700x, msi x470 gaming plus motherboard with 16 GB xpg 3200 mhz ram with an rx580 8 GB video card, and when I right click on this pc, it shows that I have 16.0 GB (7.95 GB usable) How do I make it all usable? I've tried all the methods that I've seen on YouTube to no avail. I want to have access to all of my ram, also have an issue getting the full speed of the ram, whenever I set the ram to 3200 mhz, it crashes

    Do not pay too much attention to the report in your screenshot
    Use resource monitor to show exactly how ram is being allocated
    Windows 10 resource monitor
    To get started with Resource Monitor, press Windows +R, type Resmon.exe in the Open text box
    when it opens click the mem tab
    post screenshot please
    I suspect you will find a large amount hardware reserved

    Lets sort this aspect before we move to the speed question. However I can tell you that the SPD speed for ram on that processor is 2933

    which msi x470 there are three if not four different models

    answer the other question please, sorry added after original post
    When you reply type in box that appears AFTER my post please, not by clicking reply on my post as that will, as you see, quote back all I have said.
    Would not matter if just a couple of posts between us but this could be a LONG topic

    Cheers
    I did not mean that it ONLY supported 2933 - that is the default speed of ram on that processor
    http://www.cpu-world.com/CPUs/Zen/AMD-Ryzen 7 2700X.html

    Give me some time please to check your motherboard manual
    I am about to have dinner so it will be a couple of hours before I return
    In the meantime check which BIOS version you have and check if any BIOS update offers greater ram capability

    Also check on the MSI site if BIOS update is required for that processor

    Sometimes excess hardware reserved is cured by BIOS required flash

    Also check IN UEFI BIOS - firmware setup - if ram is shown allocated to onboard graphics, it should NOT be as that CPU does not have onboard graphics, but the board as you know does have ports on the I/O plate for graphics therefore check if they are shown as allocated ram.

    If you solve it PLEASE do post to save me searching your board manual

    Further to the above
    https://www.msi.com/Motherboard/support/X470-GAMING-PRO

    CHECK I have correct board there is PRO and PLUS that is a better search link than MS7B79

    check as shown on previous post
    FOUR dim slots - if your ram is 2 x 8GB check you have it in correct slots as per manual
    Back as stated approx. 2030 UK time.

    I am not quite sure what you last post means
    I know what legacy UEFI means
    legacy is traditional BIOS for MBR - master boot record and UEFI is Unified Extensible Firmware Interface for GPT
    Globally unique identifier partitioning table

    what I do not know is IF you are now saying the problem is solved
    If it is please mark your topic so, by clicking mark solved on your opening post
