Hi Mike,
Adding more system memory will certainly go a long way in reducing the freezing or crashing, but there are other factors at play that have to be considered.
One major factor is your graphics card. If your graphics card is weak with low on board memory, or especially if it is an integrated card, this will also cause problems if the graphics card can't cope with the textures in the scene.
Also no matter how much system memory you have, if a project is extremely large or overly complex, it may eventually just put too much strain on iClone to maintain stability.
Really I think every user will soon begin to notice the danger signs when they start to reach the limits of their system. For example when everything starts to slow, and response is sluggish, then it is time to call a halt to any further growth of the project.
Ideally you should always try to break very large projects into smaller more manageable parts that you can later edit together in your video editor. In the long run it will save you a lot time and headaches.
