    • Works great so far
This package of 128GB of RAM has been installed in my 2019 27-inch iMac for two weeks, and I have not had any issues with it. It was easy to install myself, and much less expensive than having Apple pre-install their RAM, which maxes out at 64GB I believe. If I encounter any problems with it, I plan to update this post with details. ... show more

Quick shipping and my iMap as fast as a rocket. I was afraid it wouldn't happen first but it's been great

    • Repeat customer
This was my second RAM upgrade purchase with this brand and it was just as smooth as the first time. Easy to install, each card arrived clean and ready to go. A great investment for any heavy use iMac owner.

    • Great value and works great in your iMac
This worked perfectly and saved so much money versus getting the memory from Apple when I ordered my iMac

    • Works perfectly in my 2019 iMac 27"
I was looking for something cheaper than the OWC batch but still from a brand with a decent reputation. I settled on this and it worked out perfectly.

    • Does NOT work with the new iMac 27" Model MXWU2LL
While this model number is listed in the description as compatible, it is, in fact, NOT. Installed this into a brand new out of the box iMac and would not boot. And no it was not inserted the wrong way (that is actually impossible to do). When returning the factory installed RAM into the computer, it booted fine. So either it simply doesn't work, or this set was DOA. Which it should not have been, since it states in the listing that all chips are tested. So...be careful with ordering this as it might not be what you actually need! ... show more
