Thanks man. That is helpful. But I'd like to know exactly what is using RAM and when.

"Memory - The memory meter shows how much system RAM is being used by Pro Tools. If you are using Pro Tools 10 and earlier, which are 32 bit applications, then this is limited to around 3GB, irrespective how much RAM you may have installed in your computer. Pro Tools 11 is a 64 bit application, so is theoretically able to access as much memory as you throw at it. Plug-ins, particularly Virtual Instruments with large libraries use lots of memory so it is good to have as much in your computer for Pro Tools to access. However you need to remember that Pro Tools accesses RAM for other functions too, this includes; The Audio and Video Engines, plug-ins and disk cache (if available & enabled)."
