Hi Chris,
Which PDB code is running you out of memory? How are you
visualizing it? It should be possible to visualize structures
with say 5 to 10 million atoms even with only 2GB of memory
depending on how it is done. I can give you some advice if you
tell me more about what you're doing.
Best,
John
