from what I remember being mentioned in the starwars threads, they suggest using medium settings for the ship,planet and modules in your game options as they have added a fair bit of extra data to the game, which already is getting close to the 2GB ram limit for 32 bit windows programs, and the lower details settings use less ram, so you can play longer before the minidump.
by the way it is a good idea to also post system specs like the windows version you are useing( including weather it is x86 OR 64bit, the amount of ram in the computer, the type of video card, the settings you are playing at and which expansion you are playing in eg sins,entrenchment or diplomacy.
