I got this RAM to go into my 2019 5K 27" Imac. I upgraded from 8GB to 64GB with two of these kits. YOu will be replacing two 4GB sticks with 4 16GB sticks to give you 64GBs of RAM total. To access the RAM bay to perform this upgrade, I suggest spreading a soft cloth or towel on your work surface and lay the iMac screen first on the surface. Then push the monitor stand back. You should be able to see the port cover on the "belly" of the screen. A small metal port about 3inches by 3 inches, give or take. Installation was pretty straight forward, this being the second iMac I have performed this upgrade on. There is a small button beneath the Ram bay that you must press to pop the Ram Bay cover from. Once the panel cover has been removed, there is an arm that lifts the ram slightly out of alignment. Remove the two sticks and replace with the four sticks. The ram should click into place. Lower the arm back into place and return the bay cover. Then power back up and check About this Mac to verify you have the correct amount of RAM installed. If the RAM isn't slotted correctly, the bay cover will not be able to close correctly. Makes sure you orient all of the sticks in the same way. With 4x 16GB sticks of RAM, or 2x of these 32GB kits, your should have 64GB of RAM. If it does not properly show up in the About the Mac section, you may need to reseat the memory sticks until they show up as desired. If you are looking to upgrade to 128GB or more than 64GB of RAM, you will need to locate higher capacity DDR4 sticks. You can find 32GB sticks of RAM on the market, but may have to request a special order item with Best Buy. Crucial would be my best guess on ordering.

This ram works absolutely fantastic in my gaming laptop, it improves performance in games and takes a load off the ram. i got a solid improvement in fps after installing this and it was definitely worth it. Also very good for the price.

I purchased this to upgrade myACER NITRO 515 laptop that was only 8gb RAM. I did it myself and taught myself how to do it by watching youtube tutorials. Finished it in less than 30 minutes and this product worked great. i was able to play COD WARZONE without lag and tear and have better gaming experience. i am now able to multitask while cod warzone or other games are in the background process. This is a legit product and the packaging was great. Delivery is fast. Worth every cent!

This RAM has inproved my device function greatly. I probably could have done just the 2×8GB, but i decided to go big or go home. But it really had helped quite a bit with my laptops processing.

Best thing you can do for your laptop is buy 32 gb vengeance ram!
