Going to upgrade my MBP and thinking about a RAM upgrade. Not trusting too much to some 3-party assemblers (Kingston etc.) I decided to take a look to world brands (Micron, Hynix, Samsung). As I earlier dealt with OWC I went to their homepage and found along with their own branded chips also Micron and Samsung ones: http://eshop.macsales.com/shop/memory/MacBook/Pro/Core2/ The price is excellent ($64.97 for Micron and $63.99 for Samsung 2Gb chip). That's great, I thought, it's time to order! But for a start I decided to check information on Micron homepage. Yes, I found there this module: http://www.micron.com/products/partdetail?part=MT16HTF25664HY-667 But the price was $266.64!!! Almost 4 times more!!! Could anybody tell me why? I can imagine only two answers. 1. The memory OWC sells is slightly defective, not passed factory tests or something about it that not allowed it to be sold right from Micron. 2. This is not FACTORY ORIGINAL Micron memory (as OWC says) but Micron chips maybe on Micron plate assembled by OWC or some China craftsman. And additional bucks we pay not for original Micron memory but only for original sticker. Correct me if I'm not right.
