    Windows won't recognize half my RAM


    Both in task manager and system properties it says the installed ram is 16.0 GB and 2 of 4 slots are used. There is an 8.0 GB stick in each of the 4 RAM slots on my mobo and CPUZ agrees, showing 32.0 GB. I've updated my bios, disabled onboard graphics, and tried just about everything in a thread I've found here and elsewhere, nothing works. Any ideas?

    I'm missing the point.

    The OP posted that there are four 8GB Dimms installed. The MB supports up to four 16 GB Dimms.

    Does your post suggest any reason that Windows isn't showing all 32 GB?

    Guess I need to upgrade motherboard/cpu to use all 32 gb then?

    @Silariuss Please download CPU z and post screenshots (https://www.tenforums.com/tutorials/...en-forums.html ) of the CPU tab, mainboard tab and each of the 4 SPD tabs. On the SPD tab, you can select each Dimm slot from a dropdown in the upper left. Please wshow all 4 slots.I've never heard of a retail motherboard that requires 16 GB ram sticks.

    Here's the page from Crucial about the RAM combinations possibilities:

    To get Dual-Channel does require a matched pair but may be best if all 4 are matched.

    Just buy different RAM.

    Does the motherboard's UEFI recognize that you have 4 sticks of ram and show 32GBs or 32/768?
    If not there's your problem.
    Windows only recognizes the hardware that your motherboard's UEFI does, as far as cpu, mobo, ram, usb2/3/3.1, lan/wi-fi, sound and video.
