I installed the new RAM as soon as I got and it was easy to install and my computer is so fast I can’t see it change from window to window. It’s as if it’s faster than the eye can detect. Now if it’s reliable, I’m a happy camper.

Immediate performance boost for a rather old workhorse, easy to install and immediate results. Recommended.

Installed very easily, clicking perfectly into all four slots of my wife’s late 2015 5K iMac. Booted up and worked perfectly, and continues to do so daily after almost a month.

two different sets of this memory did not work on my late oct 2015 Imac 27 retina 5K, purchased new in July 2016 The first set crashed very often and Failed Memtest memory testing software tests the second set passed rember tests, but still triggered kernel panics a few minutes after reboot My Imac is very stable with the original 8Gb from apple I purchased a 64 GB memory kit from Crucial, and so far, I have not had any kernel Panics in 3 days running non stop, So I do not believe my computer or the 64 Gb configuration may be at fault. there may be something wrong with this batch. OWC is a great company and I have had no issue with their products up until now. One thing I noticed is that the memory boards appeared to require less force to insert than the apple or Crucial ones.

These worked good until one stick went bad. They were replaced and all is well.

I ordered the product on February 22th. It was written that it would be delivered in a maximum of 15 days. but it reached me in 1.5 months. I could not get enough support from B&H in this process. It was a very bad shopping experience. I have never encountered such a disgrace before.

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!

Great RAM and works fine

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.

I purchased a new iMac 27 with 8G of memory, and then purchased 32G from B&H at a large savings, compared to buying 32G from Apple. The new memory works very well.

I didn’t conduct any measured performance tests. However, it was a noticeable improvement in loading programs and processing Lightroom files. I upgraded from 8mb to 24mb With this purchase. Installation was extremely easy, open the compartment and add the two cards in the two open slots. I’m satisfied with the upgrade, but I don’t believe that I will upgrade to the max of 32mb.

Product packaging leaves a bit to be desired, but otherwise it was easy to install and my iMac recognized it right away, no problems.
