The size of the matrix is 160MB, nothing to do with 64 bit indexing.

As far as I can remember, this may have to do with memory fragmentation
under Windows.  I am sure Windows users can be more specific, and that
if you look for that keyword you should find earlier explanations, but I
suspect that rebooting the system will help at least for a while.
