Thanks to B&H chat, I was able to find the correct memory for my iMac. Memory arrived in a timely manner and was easy to install. Noticeable difference between the original 16GB and the new 64GB, especially when running Lightroom and Photoshop.

First purchase was to upgrade the RAM on my iMac. Latest purchase was for a RAM upgrade to my daughters Mac mini… Haven’t had one tiny issue! The lifetime warranty on OWC’s memory is the major factor influencing this review. I also have a review for B&H! I’ve been buying from B&H for several years now and have only positives about their site, ease of product location, convenience of included accessories specifically for what I was buying! Checkout, shipping and delivery is top notch and also a 5 star product. OWC uses the finest chips made for performance and durability. Prices are competitive. B&H- Never a let down! Always reliable and great competitive pricing… I prefer B&H over the …zon!

I opted to purchase a 27-inch iMac with 8GB of RAM and use the OWC upgrades. Installation was easy following the OWC video. Highly recommend this product!

Working fine and no issues so far

I found out that the iMac comes stock with 8gb of RAM (2x4GB chips). So to conserve space and to allow more opportunity to upgrade in the future, I went with the 32gb chip instead of the 16GB+16GB combo. Now, I have the potential to upgrade my 2019 iMac up to 128gb down the road…and SAVE LOTS OF MONEY!

Installed easily in my iMac. Since installation, I no longer have memory problems running multiple applications.

I moved my original 8GB to bottom two slots and added these two 16GB memory to top two slots for a total of 40. There are installation videos online. The trickiest part is you place the screen down so you need to protect the table with a towel to protect the screen.

MUCH cheaper option to install yourself instead of buying it pre-installed from Apple

Easy to install, works well, and is far less expensive than buying from Apple.

My order was processed and delivered in a matter of days despite the pandemic work slow down. The memory card is fantastic! Easy to install and works as stated in the description online. Would buy again.

They do not work in my new Apple 27 iMac
Arvid Botsford (verified owner) –
This is a simple but significant upgrade I purchased a 27 iMac in December 2020 but with the base memory configuration of 8GB. An upgrade to 64 GB from Apple is significantly more expensive so I decided to install it myself. The process takes less than 15 minutes and I couldn’t be happier. The reconfigured iMac is lightning fast and the difference is quite noticeable. This upgrade is so easy. The money you save can be used to but other Apple products (from B&H).
