Vista only uses 300mb of ram which is still a ton, but, there's plenty free.

I moved the slider to 0% and saw a drastic difference in crash frequency, and, like Shabitz, no longer due to Out of Memory.
I have the same issue where every few turns the game crashes. I've also noticed that the game only uses 1gb of real ram and 2gb of virtual even though I have 2gb real and 4gb virtual, though, that may be a windows limitation. (I'm using Vista btw). So what I do is when the auto save fails, I do a manual one, cause I know I'm gonna crash within 2-4 turns. I haven't tunred the silder down on the planet models yet.
I already have a new one because I just crashed from an out of memeory error >< I did email the previous one though.
I've gotten it 3 times since i started using beta ver 4. It's happened doing different things. First was turn, next was done during trade negotiations, and this last one was while clicking on a constructor. I've emailed the exception log.
