    CPU-Z sees 32GB ram, Windows 10 sees 16


    I've had two 8 gig sticks in slots 1&3 for some time. Bought 2 more of the exact same Crucial ram sticks and plugged them into slots 2&4. Bios sees 32, Windows 10 sees 16 still. CPU-Z also sees all 4 of the sticks and reports 32G.

    Tried using just the new sticks in slots 2&4. Sees both.

    Updated all the drivers, except the latest Windows 10 update - can't do that right now because I would have to uninstall an application it doesn't like.

    "BOOT Advanced Options" doesn't have a max memory limit set.

    MB is ECS Z87H3-A3X.

    Ram Has to be installed in a pre designed order of your MOBO. You could try a Ram test from Windows 10 but it takes about 45 minutes.

    All the sticks are exactly the same. Don't know how I'd change the order.

    Good thought. I'll kick that off later tonight.

    Remove your cpu and clean the contacts.

    Yeah, I read that thread. I was afraid I might have to do that. His is a little different - two of his slots were dead (at least to Windows). All my slots work but only two at a time :-D

    I'll try the ram test first - and flashing the firmware. Rather not remove the CPU unless I have to. I'd have to pick up some thermal paste first.
