  Can you be more specific about what graphical representations
you're using that are causing the memory exhaustion problem? There
may be a simple adjustment to your display parameters that can
dramatically reduce memory usage. This is particularly true for
the surface representations, isosurface, and the various ribbon/cartoon
representations which have either quadratic or cubic memory consumption
vs. their respective "resolution" parameters of various kinds.

If you share more about what representations and parameters you're using,
I may be able to give you advice to overcome the issue.

Going forward I'm working on a 64-bit Windows build of VMD, but
this has been complicated by the fact that I don't have effective remote
access to my normal Windows VMD build systems, and I'm having to setup
a new one that I can use here at home. That would ultimately increase
the amount of memory available to VMD, at least on modern machines
with say 8GB or more of memory, but I've got probably a week or two
of work to do there and I'm waiting on the next rev of the Windows
CUDA tools to be released (a matter of days now) so that I can ensure
compiler version compatiblity etc.
