Rating: 5/5 so easy, works great! February 1, 2016 can't believe I waited so long to upgrade my iMac. I bought it in 2007, and it had gotten so slow I was ready to junk it. Then I found out I could add more ram. Price was very reasonable, and I was able to install it with help from a youtube video. Computer works great! Thanks

Rating: 5/5 Excellent Value, Top Quality! January 15, 2016 I was given a 2007 Mac Mini with 1.5GB ram (which just isn't enough today for browsing), so I bought the 4GB upgrade that OWC offers. Viva la differance! Just what this little machine needed. I was experiencing the dreaded beachball almost constantly with multiple tabs open and now the beachball is seen next to never. The machine is faster, too. A GREAT, inexpensive upgrade that made a HUGE difference- from frustration to pure enjoyment. Thanks, OWC!

I did have a problem with delivery (not OWC's fault) and UPS ended up delivering on a Saturday, which surprised me. They were two days late from their scheduled delivery. Again, no fault of OWC.

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.

It installed easily and allowed me to upgrade the MacBook from Leopard to Snow Leopard to Lion. It also provided the oomph to power a copy of Minecraft. Yahoo!

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 Great up grade June 26, 2015 Took out 2MB of ram from my White Apple iMac and installed 4MB of ram in less than 10 minutes. Fired up the iMac and looked at 'about this mac' and 4MB was the the answer, Thanks. Did not have to zap the pram. NO 3.3MB. The old White Apple is faster than ever running OS X 6.8 Snow Leopard. Thanks OWC and Liz for all your help and what a great price. Received the ram in 3 days.

Rating: 5/5 Three years strong May 28, 2015 I've been using this upgraded 4GB of RAM for almost three years now. Never had any issues with it. It upgraded my 2008 black Macbook 4,1 to the highest memory settings possible and makes it run faster and more efficient than the stock 2GB RAM. Well worth the purchace. Great price. Highly recommended.

Rating: 5/5 Excellent product. I'm very satisfied with it and OWC. April 27, 2015 Upgraded the RAM from 1 GB to 4 GB on my old 2007 iMac. The Mac went from basically unusable to a pleasure to use again. I would definitely recommend doing the same to your old (or new) iMac for a better experience and less of that dreaded loading wheel while running multiple processes. First time using OWC and I will definitely use them again in the future.
