There are two versions: a 32-bit one that is limited to 4GB, and a 
64-bit one that is not. We will be releasing the 64-bit one soon, the 
release candidate is already available on 
https://downloads.python.org/pypy/. You want the one that has win64 in 
the name.

Please try it out and tell us how it worked for you. Note if you want to 
use any c-extension packages like NumPy and lxml you will have to 
compile them yourself.
