Size: 32 GB (4 x 8 GB)Style: 4 x 8GBVerified Purchase

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.

No problems at all installing in my late 2015 Mac Retina 27 inch. If you are still running 8 GB of total memory (2×4), I suggest you upgrade especially if you use Microsoft or Adobe software. I put the 2×4 into slots 1 and 2, and the new 2×8 into 3 and 4. Easy, just find instructions online. 5 minute job. Computer recognized the additional memory and now I’m flying with 24G.

Size: 16 GB (2 x 8 GB)Style: 2 x 8GBVerified Purchase

I have a late 2015 Imac. Had put in 2×8 G ” compatible” RAM by Crucial years ago. it worked fine for a few years. Then I upgraded mac os. And problems began.Half of dozen phone calls with Apple support and a trip to Apple store later, found out the RAMS are now not compatible anymore. So I was little hesitant buying RAM again at first, but really tired of the slow speed of my computer. I installed these 2 days ago.
They work well so far.

Game-changing performance upgrade for my 27″ late 2015 iMac

Reviewed in the United States on July 15, 2023

Size: 16 GB (2 x 8 GB)Style: 2 x 8GBVerified Purchase

In early 2016 I bought my late 2015 iMac 27″ Retina 5K with 8GB and a standard HDD. It was super fast running macOS Sierra, High Sierra, and Mojave. Then when I upgraded to Catalina, it went from flying to crawling. I suffered with it for years. Then recently I read something that suggested I needed more RAM. As a software engineer for decades, it seemed impossible to me that this iMac couldn’t run decently with 8GB since it already had for 3 OS versions. Anyway, I installed two OWC 8GB sticks to give me a total of 24GB and to my delight my iMac has been reborn, now as blazing fast as the day I got it. I have fallen in love again with my big beautiful iMac.
I feel very dumb for not doing this years ago, but in my defense, despite my many interactions with Apple Care over the years, not a single tech suggested this simple fix.
I’m now running macOS Monterey and it’s still super fast.

Spacious and sturdy

Size: 16 GB (2 x 8 GB)Style: 2 x 8GBVerified Purchase

Ok, I haven’t mounted it yet but just holding it and playing with it I can tell it will be great. The plastic draw is stiff, the drawer is 1.75″ deep in the main section and the metal glides are nice and smooth. The drawer will not fully extend leaving about 4″ under the desk but that’s ok for what I need. I am very happy with this purchase.

I know I haven’t installed it yet so why did I give it 5 stars? I can tell it will easily screw to the underside of a piece of wood. Unfortunately for me my cheap desk top is from ikea. It has thin masonite on the bottom and is hollow in the middle, I will have to mount a piece of plywood to the bottom so the screws will hold. Weekend project.

What the heck does Sheerness mean (it’s an option for ratings)?

Worth the purchase.

Instant difference in my late 2015 iMac. Made it feel like a new(ish) computer again. I notice much improved performance in running photoshop.

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.

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 (2×4 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.
