Purchased this Samsung M471A1K43CB1-CTD 8GB DDR4 2666MHz memory module back in 2020 (4 years ago and going strong), and it's been an excellent upgrade for my laptop. I paired it with an identical Samsung module to boost my system's RAM to 16GB, and the performance improvement was immediate and noticeable. The installation process was straightforward, and the module has been running smoothly without any issues. It’s been reliable for everyday tasks, multitasking, and even more demanding applications. I highly recommend this memory module for anyone looking to upgrade their system’s RAM, as it offers great value for the price and the performance boost it delivers.

Bought this 12/19/2022 for my DS720+ and in May 2025, began to fail. Maybe I got a bad one, but for the price, buying one every 2 years is okay for me. FYI....recommend doing a memory test the moment your NAS begins to restart randomly or you cannot log into DSM even though SMB into it works. Those are the signs of a failing memory. Also, always have a backup of your data!!!!!!!! Lost all my data 4 times because of memory failing. Also, no notification from Synology that it's "unofficial". The internal RAM that comes with the DS720+ is actually Samsung, so it's best to stick with Samsung if you want an increase. With the RAM installed, the difference in performance is like night and day. Would never use a DS720+ without the extra 8gb this adds (Unless it fails and I'm waiting for Amazon to deliver the replacement lol) Let's hope this one lasts more than 2 years for me again!!

Works perfect. Maybe a bit slow? But my laptop is kinda cheeks so idk its probably a bottleneck.

Needed it for my mini PC which already had an 8GB stick installed and increased the total to 16GB. Using it for old games and is holding up well so far

Purchased this ram for my wife’s all in one computer. She normally has multiple windows open for work and she would constantly complain how slow it was. I researched reasons why computers run slow and insufficient ram was the number one cause. I checked the ram on the computer and it was at 100% capacity. By purchasing this additional ram doubled the capacity and was very easy to install. Immediate performance improvement! I definitely recommend this ram because of price, exact fit and ease of installation. Btw, I know nothing about computer repair so I took a picture of the original ram to make sure I ordered the right one with the right speed and capacity.

Great mem stick for my nas 920+ no warnings and asap working
