Moved a stick of RAM. The bios still "sees", but won't use it or count it towards total memory.

    Question

  • Hello all,

    Recently I opened my case up to take a look at how and whether I would be able to configure things to start using an SLI setup. While I had the case open and the motherboard manual out, I noticed that the company who built my computer didn't plug the RAM into the optimal slots according to the manual, and that they hadn't connected the front chassis fans to the motherboard. I fixed the fan issue, moved one stick of RAM (they had the other in the right spot), closed the case up, and moved on. I later noticed in task manager that the amount of RAM was half what it used to be. I checked in the BIOS and saw that both sticks were shown, but the second wasn't added to "total memory" in the BIOS. I updated the BIOS and checked again: same result. I ran the Windows Memory Diagnostic Tool (2 passes normal, then 1 pass complete), and it told me it couldn't find any problems.

    Possibly involved parts:

    Motherboard: ASUS X79-DELUXE

    Bios Version: 0901 (Just updated to try to solve the problem)

    Memory: Kingston HyperX Blu DDR3 1600MHz (2x8GB)

    OS: Windows 8.1

    If you have any questions, let me know.

  • The easy answer is to move it back where it was.
     
    As for being the most optimum, hard to tell, it could be the manual was
    wrong, or there is something wrong with the PC, and for that, you're going
    to have to contact the PC's manufacturer.

  • I moved it back and it worked, so I moved it to the "new" slot, and it still worked. I'm guessing it was seated enough to be recognized, but not to be useful.

    Thanks!
