I can compile with -j40 on 16GB if I want, Windows will just use swapfile, it takes much longer that way, and thrashes the disk like hell, but no out of memory.

If you're trying to use a 32-bit environment or something, keep in mind that's no longer officially supported, and on the machine you have, there's no reason to do that.
