I Bought this computer to work with multiple software instruments at the same time in my DAW (primarily Apples MainStage 3) and it absolutely smokes other top of the line MacBook Pros Ive had in the past. I bought a MacMini with 8GB of memory on purpose and bought this 32GB of memory from BH at the same time since it is just as good but a fraction of the price of buying Apple Branded RAM. Super easy to install (although you DO need to buy a SAFETY hex screwdriver set – cheap on amazon but NOT in your local hardware store. SAFETY hex screwdrivers have a pinpoint in the middle of the driver to work with safety hex screws and regular hex, star, or Allen keys will not work). Once the 32GB of RAM was installed the computer was unstoppable!

The RAM works great and in dual channel paired with a Kingston HyperX 16GB Module. My laptop has a quirk that it can’t work on the low latency of the HyperX RAM by themselves but will work paired with another chip that defaults the latency higher.

If you’re not really experienced in this you might do what I did and order this SODIMM memory when you should have ordered DIMM. SODIMM is a small card for laptops; DIMM is a long card for desktops. BH was kind enough to let me return it but I had to pay a restocking charge and return postage. My fault.

So I purchased this RAM for my iMac 2019 27in 5k because the base RAM is laughable for such an expensive machine. That being said it was a breeze adding the additional 16gbs of RAM to my iMac and it works great, the Mac runs even better than it already did. Highly recommended for an upgradable PC or Mac.

I have always purchased and installed this for any Mac that is end user upgradeable. Their lifetime warranty is a great feature and they are true to their word regarding replacing RAM that fails.

The most difficult thing was removing the back cover of my laptop. After that it took 2 minutes to remove the existing memory and insert the two 16 GB memory modules. I reattached the back cover and I was done. The increased memory has dramatically improved performance.

Just installed two 16gb modules along with two 8 gb modules in my early 2019 27″ iMac. I now have 48 gb of RAM. It’s been a few days and it’s working perfectly. Plus my heavy load of photographs are no longer crashing programs or getting stuck. I noticed that with all the usual programs running plus jamming to music I am monitoring RAM usage falls down to about 15 gb out of the 48 gb. I don’t know I didn’t upgrade earlier. BH fast delivery is top notch.
