That plugin is definitely useful to speed up Vim with large files
and to use less memory.

Vim has to load the entire file in memory (unlike a few editors
that can load on demand). However, I would not expect crashes
or running out of memory on a 3GB file with 32GB of RAM (and
possibly more of virtual memory).

Which version of Vim are you using?
Can you get a stack trace where it crashes?
Make sure you use the latest version of Vim to avoid wasting time
on bugs possibly already fixed. I see a recent version of Vim
for Windows here:
