It's known that no name ram memories are a lot cheaper than brand ones. My question is : do you have good reasons (besides lifetime warranty)to stay away from no name rams? Anyone have had problems with those? Making a parallel, are there differences or they work exactly the same way? Brand is what makes the cost difference or it's something else? I've seen people selling AUM memory macbook compatible on ebay at very good prices, anyone have used/heard about AUM?
