Old iMac is now new again
I upgraded a 27″ Late-2015 iMac from original 8GB (2 x 4GB RAM) to 32GB (4 x 8GB RAM). The computer is now fast again. No latency or maxed out memory resources. I can run multiple apps at one time again without the computer stopping or forcing to quit an app that is not responding due to memory conflict.These OWC cards are perfect for this application. Install took just a couple minutes. Should have done this long ago. I have effectively a new iMac for less than $75.

Perfect Upgrade for a Late 2015 iMac
I recently upgraded my 27-inch iMac (Late 2015 model) with the OWC 32GB (4 x 8GB) PC14900 DDR3 1866MHz SO-DIMMs, and I couldnât be happier with the results.The installation was a breeze. Even for someone who doesnât tinker with hardware often, the process was straightforward, thanks to OWCâs design and compatibility. Within minutes, I had all four sticks installed, and my iMac recognized the full 32GB of RAM without a hitch.The difference in performance is night and day. My machine, which was beginning to show its age, now feels incredibly snappy and responsive. Multitasking is effortless, with no lag even when running resource-intensive applications like Photoshop or Final Cut Pro. Itâs like breathing new life into my iMac without having to shell out for a new computer.If youâre using a Late 2015 iMac and want a significant performance boost, I highly recommend this OWC RAM upgrade. Itâs a cost-effective and easy solution to keep your system running smoothly for years to come.

Works as anticipated.
The ordered RAM came quickly, appeared to be as described, was easily installed, and appears to be working as anticipated. All around a good experience.

Cost-effective performance upgrade
I installed the 2 x 8 GB cards into slots 3 and 4 after moving one 4 GB card into slot from slot 3 to slot 2 on my late 2015 27 inch iMac. Thus far, I have had no problems and the OS recognizes all 24 GB (2 x 4 GB original + 2 x 8 GB OWC cards) and boots with no problems. I’m not sure if the ordering of the memory cards is important (and neither was the Apple expert I contacted over the phone help line), but my configuration worked for my system so there was no reason to experiment with other arrangements. The computer loads programs and web pages faster and I no longer get the error messages that I am low on memory. Bottom line: Without doing a rigorous quantitative performance analysis, this upgrade with OWC memory cards worked for me as expected and was a very cost-effective upgrade.

Some of the best money ever spent
I had a late 2015 27in Mac with 16gb in it. After discussion and research with apple and others, I decided to upgrade all 4 8gb sticks instead of just adding 2, I now have 32gb. I cant tell you how much better my machine runs, everything I do from programs to internet. I have fallen in love again, lol. We all love speed. This is a respected brand, was super easy to install and worked instantly. Apple charges $200 for 8 gb, I got 32 for $80.

If you have an iMac with a pitiful amount of ram you need this.
I have an iMac Retina 5K, 27-inch, Late 2015 4 GHz Intel Core i7. I was running 16 GB of ram and thought it was fine. Little did I realize what a difference it would make by bumping up to 32 GB. Installation was a two minute job. And being that the vendor is OWC it’s a no brainer. They have the best stuff for macs hands down.

No issues with product or installation
I wanted to upgrade my iMac late 2015 5k to a full 16GB of ram with a quality product and that’s exactly what I got. Found the ram specifications on the iMac and confirmed those specs with the OWC website. Felt confident with product compatibility. Located a OWC product video and proceeded to install the pair of 4GB ram modules with no problems whatsoever. iMac instantly recognized the install. Very happy with the entire process. I would have no concerns recommending OWC products.
