Absolutely. Stata for 64-bit Linux running on an Opteron with enough
memory can allocate as much as the operating system is willing to give it.
With 16 GB of memory on a system, you should be able to allocate 15 GB
or more to Stata assuming there is not much else being done on the system.

Yes, a 64-bit Windows version of Stata, when available, should be
able to allocate a similar amount of memory on a 64-bit Windows machine
with a similar amount of RAM. We do not yet have an anticipated date
when we think a 64-bit Windows version of Stata will be available.
