It is also worth noting that you can use the /USERVA switch to tune
the amount of RAM that is available to "large address aware"
applications. That extra GB comes at the expense of RAM available for
the kernel and some applications can run into issues when the kernel
is squeezed. I specifically had issues with the LANDesk remote
management tools on a machine with 4GB and I had issues with
enumerating files on network shares on a machine with 3GB of RAM.
Giving back a 100 MB or so by setting /USERVA=2900 solved the issues
in both cases.

By default I run my machine with the /3GB /USERVA=2900 switches and
have had no stability or compatibility issues to speak of.
