It is possible that this is because of a flaw in your code and adding RAM will not fix it. It is also possible that the calculation is just too big (in this case adding RAM may help), but I strongly suggest to try to optimize the code first. Any suggestion will involve code modifications, so I cannot say much ... Learning about packed arrays may turn out to be very useful. There's also Share[] (which might actually increases mem usage a little before decreasing it) and $HistoryLength = 0 can be useful, too.
