Rating: 5/5 Prompt Service April 9, 2017 Ordered some RAM for an old iMac G3 I wanted to fix up. Those old small RAM modules are hard to find. Order came promptly, and was exactly what I needed. Piut them in and they're working fantastically!

Rating: 5/5 This product is working perfectly for my classic mac August 13, 2016 I recently got a powermac 450 with 256 MB memory that made it is ok by running OS9. Now it indeed is upgraded after being filled with 4 slots of the products 512 MB. Besides, I don't have to worry about the fitness between a classic mac and the new purchases. I could purchase any specific products I needed for my computers from OWC and they just fit perfectly.

I would recommend this item to a friend! Customer Videos:

Rating: 5/5 Works! April 6, 2013 Bought this (3 of them) for my old Power Mac G4 Cube. I'll just say that it works perfectly. Computer feels about as new as a 13 year old computer could. I can run Adobe Photoshop CS well enough. Also, I don't know if it is related or not, but the sound through its USB speakers improved ever since I installed and maxed out the RAM. (Prior to the RAM upgrade sound was garbled via USB speakers. Perhaps the added memory allowed it to better transmit sound via USB? I have no idea honestly.) The only negative comment I can say is that my brother ordered this item a couple years back and the RAM modules were an awesome bluish-purple color but mine were generic green :(

I would recommend this item to a friend!

Rating: 5/5 This memory works fine May 26, 2012 This product is perfectly suited to my old Power Mac G4 400 MHz AGP (sawtooth) running Mac OS 10.4.11 (Tiger). 2 GB SDRAM avoids incessant swappings on the hard drive and thereby improve its performances.
