    I have 32GB of RAM. My computer only recognizes 16GB of it.

    I'm running Windows 10, version 1903 (OS Build 18362.592), and have four 8GB sticks of RAM installed.

    My computer has been working well for years.
    Today, while using the computer, it crashed, giving the 'Memory Manager' error code. I reseated my RAM, and it seemed to have fixed the issue. Then it crashed again, giving me a 'Kernel Data Inpage Error.' After reading up on some forums, I ran the Memory Diagnostic Tool - no errors detected. Finally, I checked my BIOS and was told that I had 16GB of RAM installed, despite having 32GB.

    I've tested each stick individually, and all of them show 4GB when they're 8GB sticks of RAM.

    I've scanned multiple forum threads on different sites, and the common solution is to check msconfig and uncheck the 'maximum memory' option in the 'Boot' tab. Upon trying that, the box was already unchecked, and after checking the box, restarting, unchecking the box, and restarting again, I still only have 16GB.

    I've spent hours on this issue, trying every individual stick of ram in each of the 4 slots, and nothing has worked.

    Is there something I'm missing? Have I been cursed by the gods?

    How much RAM does the BIOS recognize?
    Have you made any changes to the system before this started happening?
    Did you always have 4 sticks of RAM?

    The BIOS recognizes 16GB of RAM.

    I haven't made any changes to the system. I'm not all that knowledgeable when it comes to software stuff, and I know just enough about hardware to actually build a PC.

    I started with 2 sticks, and then upgraded about a year ago with no issues.

    You say you know enough to build a PC and that you upgraded the RAM.
    Did you build the PC you are having issues with or is it a pre-built that you added more RAM to?
    The reason i ask is that if it is a "brand" PC (Dell, Acer etc) it is possible the firmware has been updated through Windows update and that is causing the issue, it's not entirely impossible for a firmware update to make things worse sometimes.
    Can you post shots of your BIOS, specifically the RAM pages if any, use a phone if you can't save to a USB from the BIOS.
    Also can you run a utility such as CPU-Z or HWInfo64 (there is a portable version of HWInfo, no install needed) and post shots of the summary and memory pages.
    Also a shot of taskmanager showing the Performance page, then click on the Memory category and post an image as well.

    It would really, really help to know what make and model the motherboard is. It's impossible to offer any relevant advice without that information.

    I built my PC. I had a friend help me pick out the products, I purchased them and put the PC together myself. The motherboard I have is a Gigabyte Z97-HD3 unit.

    The next question is what RAM do you have installed and is it on the supported list?


    RAMMON may help you determine what RAM is installed:
