    I'm not a AMD user.

    Just some suggestion on my part.

    I will set back and watch.

    That's pretty much all I can do at the moment too, and going to bed soon.

    Well I built the pc myself, I will try re-seating the RAM sticks today, but they are definitely matched sticks, they are 2x8g sticks,
    from the same packet, all numbers on them match.
    I haven't changed any settings in the bios for the ram speed or timings, I bought 2100mhtz DDR3 RAM assuming it would de-clock itself to the correct setting maybe this is the issue.
    It says its running at 1866mhtz but I can set it back to 1600mhtz and I will let you guys know what happens within 24 hours.
    The 2100 ram was as cheap as the 1600 ram is why I bought it. I know sabertooth boards don't like anything over 1728mhtz usually but I just never thought of this, so thanks people I will go test this stuff out and get back to you all.

    The reason I need more RAM than 8g is, I am a game tester for Empyrion and I have been doing huge world tests and I am eating RAM like its going out of fashion.

    I have an Intel system, 5960x i7 @ 3ghtz, with 16g ram @ 2100mhtz, gtx980 video ,x99a mobo, where the maps in Empyrion will use more than 8g of ram on some of these maps, I really need to get the AMD system up to speed with the amount of RAM available to use to do proper testing.
    Empyrion is a game like Space Engineers, very demanding on pc recourses.

    Thanks for every ones time on this, much appreciated.

    It is possibly a misconfiguration, keep us posted :)

    I am running 16GB on 890FXA no problems with 1600MHz.

    It wouldn't hurt to go here: MemTest86 - Download now!

    Get the Image for creating bootable USB Drive under the Windows Downloads section, then give it two or three passes. I'd do the re-seating and configuration things the others have mentioned first, though. :)

    OK hello everyone,
    First I want to thank every person who put a reply in here.

    The problem has been resolved.

    Special thanks to Layback Bear, and GoKay, the problem was indeed the RAM speed setting, I re-seated RAM, had no effect, so I then entered the bios and manually set the RAM speed to 1600mhtz as it was setting it to 1866 automatically, at 1600mhtz it reads the full 16gig and it has access to use the full 16g.

    So thanks for the effort to help me resolve this niggly problem, I have 20 odd years of building pc's [W3.11 ! ] and I am not a pc technician or programmer, for me I learn something new every generation of cpu !
    Thanks for the education .
