The amount of physical memory you have is irrelevant.  What's important
is virtual memory and memory fragmentation.  You might want to read up
on these concepts.  I suspect fragmentation is your problem.  Because
you are dealing with large datasets, you might want to consider building
your code as 64 bit.
