unfortunately the large address aware can CAUSE crashes in the operating system (unless you are using a 64 bit OS) and also in the applications, so the best means of improving the stability of the sins game is to LOWER the graphical settings from highest to medium or lower depending upon how muh RAM is in the system and how large a map you want to play on (the lower graphical settings also has a sideeffect of helping to speed up the game engine a bit by giving less detail to be calculated for EACH of the MANY thousands of ships, strikecraft, planets and asteriods that are continiously worked with each game 'tick'.
