The addressable memory will depend on the operating system. WinXP  
under the best of circumstances may have 3.5 GB of capacity, whereas  
Linux and Mac OS (Leopard with 64 bit binary from ATT site) will be  
effectively constrained by your RAM budget. I am using about 1/2- 3/4  
of my available8 GB memory when using a workspace that contains  
multiple models (which consume 150-300 MB each)  and a primary working  
dataframe that has 1.5 rows and 110 variables.
