    Could be a BIOs limitation or a video card siphoning. Check your video RAM, it might of 'stolen' some of it.

    GPUs share RAM with the main system most of time, especially if the GPU does not have its own dedicated RAM, or, if you have a dedicated GPU, the onboard memory on the GPU may not sufficient.

    If you have a integrated GPU, or a dedicated card, with a name such as "TurboMemory", the GPU will take some RAM.

    Question why would video siphon with this config and not other? I have "Hypermemory" it does not report as RAM "missing" because it is avilable to both system and GPU.
    I would run CPU-Z and see how it reports each stick together and seperate, I would even switch which slot you put the RAM in, couldn't hurt? SiSoft can tell you how much RAM your MoBo can support. This will give you info whether it helps I don't know, good luck.

    What are you using to measure Ram if using "sys properties" then Cpu-Z should tell actual RAM installed.
