hey I've got a pre SR macbook and want to up the ram. I'm aware my macbook will only support up to about 3.2/3.3 gb of ram but I'm just wondering the best way to achieve this. 1) Buy a 2gb stick and a 1gb stick. This would be cheaper and less wasteful. or 2) Buy 2X2gb sticks and let the macbook recognise 3.2 of it. The only reason I'm thinking of this is just because in my searches everyone is agreed that ram should be in matched pairs but seems wasteful. Will this REALLY make a difference to me? I use Logic Pro, Parallels and just general stuff.
