There are problems with memory at and over 2GB with XP. One of them is that XP splits that 4GB of RAM so that an
application can only access 2GB of RAM. The OS takes the other 2GB. You can use the /3GB switch to split the
application address space to 3GB and 1 GB for the OS. Lot's of problems reported with this though most of them should
have been worked out by now.
On 64 bit you are looking at a potential of Terabytes.
2003 Server and a few other 32 bit MS servers can be configured to up to 16 GB and more. Though the memory management
techniques are only for the brave.
I've seen FS9 use all 2GB of memory on a friends machine. Though he was experiencing crashes. Not sure if he ever
worked that out or not.
