impossible to say from this information.
you have about 4.5GB RAM available. with 437660 atoms at 12 byte coordinate
storage per atom, you should have sufficient space to load about 900 frames
from your trajectory file(s).

the memory consumption while loading the file(s) can be monitored with the
usual tools like top or htop.
