    • What a difference! fairly easy install, cheap, a world of a difference
Size: 32gb Color: 4 x 8GB
Review Image by Nicolas. g
Imac 2019 5k here. 8 Gb out of factory from 2x4 ram sticks. I tend to have a lot of things opened at the same time, but nothing out of the ordinary, a few chrome tabs, a few safari windows , WhatsApp, mail... It was ok with 8Gb but not lighting speed. I was getting the color wheel when trying to open a new tab sometimes. I Wasn't sure how much ram to get from Amazon but the cheapest approach was to do 4x8 since I dont do video editing or anything crazy, I didn't thing anything over 32 would be useful. Install: So they tell you to lay the Mac flat, which I didn't do. I installed the new ram with the iMac vertical: I removed the old old and put the 4 new ones in place I closed the memory compartment and the Mac wouldn't boot a few times I thought I installed them correctly but YOU HAVE TO MAKE SURE EACH IS FULLY, FULLY, FULLY in. A slight off position and your computer won't boot. After trial #3, the Mac booted no problem. Back to were I left when I turned it off prior to ram upgrade. I am now using about 10gb of Ram out of the 32 available but the Mac monitor, with the same apps opened as prior. The difference is night and day when I do something, wether it is a webpage or opening iPhotos or pages, it is just instant. At $150 , it is overall a cheap upgrade given how much money we put in our machines. Super happy with the purchase given the amount of time I spend on the computer, I appreciate the smoothness. ... show more

    • Very easy to install
Size: 32gb Color: 4 x 8GB
Packaged and shipped to prevent damage. Followed up with me to ensure I didn’t have any problems or issues. I installed in my new 2020 IMac. Cost was a lot less than what Apple wanted to charge me for the same memory.
