Rating: 5/5 Like having a new computer!! March 23, 2012 I have an old Mac G4 PowerBook, originally purchased back in '03. Basic tasks slowed it down to the point of being nearly intolerable to use. Two upgraded Memory Modules have this Old Girl running like a Spring Chicken! And they arrived in half the estimated shipping time given when I ordered them.

Rating: 5/5 Do-It-Yourself Installation, Great Price, Why Wait to Upgrade? October 5, 2011 Service by phone and fast delivery by USPS ground was outstanding. I added a Wireless USB to the order. Now I can use my Powerbook G4 a bit longer. I won't hesitate to order from OWC again.

Rating: 5/5 Worked perfect in iMac G4 1Ghz February 24, 2011 Hello, I wanted to speed up my old iMac G4. I trust OWC's RAM since I have used it in my iBook G4 1.33Ghz machines. Really made a difference in boot time, launching programs and shut down. Very satisfied. Didn't want to take a chance on some other brand that might or might not work...

I would recommend this item to a friend!
