Rating: 5/5 Good memory November 20, 2015 This memory performs as you would expect from DDR2 667 MHz RAM. Of course, people familiar with computers will realize this type of memory is rather dated. But this memory, in a matched set, performs well for what you'd expect. I bought this to upgrade a laptop from 2007. Installed it as well as a new 7200 RPM hard drive, and that old 2007 laptop actually runs with nearly the kind of responsiveness you expect from modern computers.

5/5, excellent product.

Rating: 5/5 Maxed Out MY Laptop RAM August 29, 2015 I purchased a used 2008 macbook pro 15" with only 2GB of RAM. Not knowing anything about them really, I figured I order 8 or 16 or more GBs of RAM and max it out for top performance. Then I went to the OWC RAM pages to find that 4GB is the official max. (you can add chips larger than 2GB to each of the 2 slots and get a slight improvement - but I didn't want to push it). I've been doing just fine, surprisingly, and enjoying mobile computing for my photography hobby.

Rating: 5/5 New Life into an Old Friend August 3, 2015 I added a new hard drive and went from 2 to 6 Gig of ram in my mid 2007 iMac last week. The huge improvement in speed was noticeable instantly. Glad I went for 6 instead of the 4 that Apple says is the max. Wow, what a fantastic difference! I would recommend these upgrades to anyone who feels their old iMac has slowed down. The 'how-to' video for the hard drive made the process absolutely simple. Thanks for a great product and straightforward video.

Rating: 5/5 Pushed an old MacBook to 6GB August 1, 2015 This 6GB kit pushed my bargain MacBook to standards it did not have when it was new. Friends are amazed that I purchased this 2009 MacBook for $100.00 and then upgraded it with a hybrid SDD drive and 6GB of memory. I needed an additional computer with OS 10.5 in order to run some older software. Thanks to OWC, I have what I need.
