Rating: 5/5 First out of the memory box June 27, 2017 Ordered a new 27-inch iMac from Apple with stock ram. Other World Computing had the new modules within days of Apple's release. Ordered 2 x 8 GB modules and it arrived 3 days before the iMac. Installed the ram before even turning on the computer. Worked like a charm. I've always had great success with OWC ram and this is another winner.

I would recommend this item to a friend! This review is from 16.0GB (2x 8GB) 2400MHz DDR4 PC4-19200 SO-DIMM 260 Pin CL17 Memory Upgrade Kit. Customer Videos:
