I upgraded my late 2015 iMac 27 with 32GB of OWC memory. It took about 2 minutes to remove the factory RAM and install the OWC RAM. My iMac immediately recognized the memory and has worked flawlessly since. Highly recommended.

This product was super easy to install and only took about 2 minutes total. Once the computer is rebooted, there is no need to do anything. It just works. Performance has improved greatly, especially using Lightroom. 10/10 would recommend.

I didn’t read the reviews on BH before buying, I just went with Hey it’s an OWC product! Fantastic!… I was wrong. I don’t know what’s wrong with these memories but if you buy the 64GB kit you’ll be dealing with tons of restarts when you are trying to create smart previews or export a bunch of images on Lr.

As good as OEM RAM. Nice addition to get a bit more power to avoid the spinning beach ball in Photoshop and Lightroom. Value for your dollar.

Ordered for the 27 loaded iMAC 5K 8 gig ram… Added the 32gig in about 2 minutes and saved $600 off what apple charges. Unfortunately, it did take a few extra days to get the memory but it was worth the wait.

I decided to try an upgrade from an 8BG RAM to a 16GB RAM because of two issues. One, my activity monitor, at times, indicated a small degree of Memory Pressure, and two, I thought one of my main programs probably needed more RAM. Very happy so far. My Activity Monitor now seems to indicate 10 to 12GB of memory used, so I assume my additional 8GB of RAM is helping. Not sure I can actually tell the difference going from 8 to 16GB of RAM but the additional RAM appears at least to be useful according to the Activity Monitor.

I don’t think it is good for iMac 27 5k 2015 late version. When I put into the iMac is not that stable. It will temporally restart. I don’t recommend ppl buy it. I think that is why Apple they don’t have this option. I hope it can fix this bug.

Worked for my late 2015 iMac 27 inch Retina display. Don’t buy apples ram it’s a waste of money. Buy this ram. It’s super easy to install and it works like a charm. If you’re unsure on how to install it there are great YouTube videos that will walk you through it.
