Description

OWC MEMORY: Memory made for your Mac. At OWC, we want your Mac to perform faster and last longer. That’s why we engineer memory specifically tested and optimized for Mac. There’s OWC memory for nearly every upgradeable Mac, from the PowerMac G4 to the latest 2017 iMacs. Plus we make it easy to upgrade by yourself with step-by-step install videos, and included toolkits. It’s the easiest way to improve your Mac’s performance. OWC memory is specifically engineered for compatibility with your Mac. We start with the highest-quality components, and then create memory to the exacting speed, capacity, and programming specifications of nearly every upgradeable Apple computer. The result is JEDEC-compliant memory that’s a perfect fit for a faster Mac. ​ Memory Upgrade Kit compatible with Late 2015 iMac 27" with Retina 5K Display Compatibility: Late 2015 iMac 27" with Retina 5K display: iMac w/Retina 5K display (27-inch Late 2015) (October 2015) Model ID: iMac17,1 3.2GHz i5, 3.3GHz i5, 4.0GHz i7 MEMORY THAT GOES FURTHER: OWC memory is hand- checked and tested for quality at each step in the manufacturing process. But it doesn’t stop there. We own and maintain state-of-the-art facilities that feature nearly every Mac manufactured over the past two decades. That’s because we don’t just relentlessly test for quality and reliability. We test in actual machines to make sure OWC memory is optimized to deliver a lifetime of superior performance in your Mac. It’s the OWC Difference. We’re laser- focused on helping you get the absolute most from your Mac. So we test the true memory limit of each Apple computer. We found that most Macs support more memory than the official factory maximum. With OWC memory, you can truly max out your Mac with up to double the factory-supported limit.

  • It just works!
Size: 8GB Style: 2 x 4GB
I used this to add some DRAM to my iMac. I didn’t know this upfront, but installing DRAM in a Mac is super simple. There’s a little hatch on the back of the machine which pops out. You can then simply slide in the new DRAM and you’re done. $30 to double my DRAM from 8 to 16GB is a great deal.

If you have the kick-ass but slightly dated imac these are for, do yourself a favor and install these. Makes a HUGE difference and you don't need to buy a whole new computer.

  • Works like a charm
Size: 16 GB (2 x 8 GB) Style: 2 x 8GB
Installed these in our late-2015 27" iMac, which had trouble keeping up with today's memory-hungry browsers and apps. The iMac already had 8 GB (2x4 GB) installed, which I kept, giving us a total of 24 GB RAM now. I put the new 8 GB modules in slots 1 and 3, where the 4 GB modules were before, and moved the old 4 GB modules to slots 2 and 4. No problems, all running well. Just to clear up any doubts: It is perfectly fine to mix different-size memory modules in this iMac model; Apple officially states this in their support article about upgrading the memory. Happy upgrading. ... show more

  • The best alternative to Apple
Size: 32 GB (4 x 8 GB) Style: 4 x 8GB
Works perfectly! I installed 4 of these in my late 2015, 27 inch iMac.. for a total of 32 Gig. The RAM speed is 1867 mhz, as advertised. Great for video editing software like Adobe premiere pro and after effects.
