You shouldn't mix and match different types of ram.
I don't know what combinations are okay if any, but even if it seems to work okay right now, who's to say it won't crash when you try to run some demanding application like a game?
If you need more than a gig of ram, you should probably just get another couple 512 sticks of the same brand.
