Dear SoaSE Community,
I came across this handy tool, that enables any exe to use more than 2 GB of memory (even on Windows XP, instructions in the readme). I edited the bat files to work for SoaSE, SoaSE E and SoaSE D.
I modified my SoaSE Exe and both addon exe files with it and now I can play SoaSE with mods like Distant Stars on highest details without getting a minidumb.

It surely will disallow you to play online, but I am not sure. You can try it, if you risk BUT I'M NOT RESPONSIBLE FOR IT, IF YOU GET BANNED! (Therefor the Tool renames the modified exe files, so that you can launch the normal SoaSE and the 3GB Enabled SoaSE)
I hope this tool will be of use for some people
