hmmm im not too sure sorry. I was always told that the top command was not a good way to find out exactly what is using your memory, as it has issues or does something weird with your page file. Another idea is that it might be your video card that driver that is consuming your RAM (if your computer is running a GUI). My computer allocates 1gb of memory to the video card (I have 8gb of RAM too).
