I've been a long time customer of OWC and have been using their RAM for years. Why? Because when one of my sticks of RAM gave up the ghost a few years ago, OWC replaced it for me at no charge. This is why they are my goto shop for memory, and have gained a lifelong customer.

There is not really much to say here, other than that when OWC say their memory upgrade kits are compatible with a certain hardware that claim can be totally relied on. I wholeheartedly recommend the OWC memory upgrade kits.
