ok so i bought a 1gb stick fro Kingston that is on its way via fed ex. I've been checking the status and i noticed that they might be shipping me memory i did not want? this is what is says when i review my cart for the item shipped: Kingston 1GB DDR2 SDRAM Memory Module - 1GB - 333MHz DDR2-667/PC2-5300 - DDR2 SDRAM - 200-pin SoDIMM is this memory 667mhz or 333mhz, it was suppose to be the faster one. when i trace the steps i took from kingston.com --> macbook and so on, i got it from buy.com it was the cheapest, it all seems to be what i wanted in terms of speed and size. but did i get played here?
