Yeah, if its a ram problem, this will fix it
2 games it works well on, sins of a solar empire: diplomacy and the original supreme commander (expansion shipped with this already modded).

And if you mod a file and give it to someone for their windows XP machine, it won't hurt it, XP will just ignore the setting
