This product has really improved computer speed. We were having issues with our computers slowing down when we were using Adobe Design Programs (InDesign, Illustrator, Photoshop) but now it works great. Shipping was super fast too!

I purchased 4 sticks instead of buying the bundle pack to save a few bucks. Installed in a brand new iMac and my computer kept hard crashing in davinci resolve. I thought it might have been the computer but come to find out one or more of these sticks were bad. Re ordered the bundle pack and all is working now.

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.

Received late 2015 5k iMac the same day as the memory. Installed the memory and it was recognized so I thought nothing of it. Exporting and working with files in davinci resolve 12 kept hard crashing my iMac so I thought something was wrong with the computer itself. Before I contact apple I just happen to put my factory 8 gigs back in and everything works as it should. Too much of a guessing game to figure which stick is bad so I’m sending them all back. The iMac kept freezing during diagnostic with those sticks in trying to figure which one was bad. Mine was the 32 gig but I’m sure it’s what the above comments are experiencing as well.

I decided to increase the memory in my iMac from the original 8GB to 24GB. The installation was simple and smooth, but I have to admit Im disappointed that there does not appear to be a significant boost in speed or overall performance.

I bought an iMac with the standard 8GB installed memory and wanted to bump it up a bit. But I was surprised that B&H sells OWC memory. I normally buy my memory from OWC, but I had a delivery issue, which is why I came to B&H.

The memory is fine and was easy to install except that the computer crashed repeatedly after installing the memory. I ended up having to remove all the memory from the computer, including what was already installed, and reinsert each card, with the new memory going where the existing memory had been installed. I did do this in pairs and upgraded my 8GB to 24GB total. I have had no problems since then.

Adding more memory to my iMac was super easy and made Lightroom run much faster. It’s also WAY less expensive than buying it pre installed from Apple. Highly recommended!

I got 64gb kit for my late Imac2015 and I have no problem with it. It works great ! I don’t understand why people told , it does not work but mine has no problem.

I have been wanting to upgrade the RAM in my iMac for some time now. It wasn’t until I searched how to do it that I discovered just how easy it is to do. I came to the B&H website, as it’s my go-to for electronics and photography gear, and found the perfect memory kit for my machine. Once it arrived, it took me more time to unhook my iMac than it did to install the memory. It works flawlessly and has sped up my photo processing tasks.

For a while I was completely unaware that I could easily upgrade the ram on my iMac. Found out what I needed, ordered this product and everything is running much better now that I have 24gb If youre combining these cards with existing ram place the new ram in the slots that are being used by the old and move the old ram to the spots that are not being used.

Works as it should at 1867Mhz in 27 iMac.

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.
