I was actually wondering if the problem went the other way: 257M unique relations sounds like an awful lot for a 31-bit job. Is it possible that this is too much oversieved? Can you build a matrix with higher density if you cut down the relations to e.g. 210M? It's counterintuitive, but I've seen this sort of thing work before.
