A-Tech 128GB Kit (4x32GB) DDR4 2666MHz PC4-21300 ECC SODIMM 2Rx8 Dual Rank 1.2V 260-Pin RAM Memory Upgrade Modules for Microserver, Workstation, and Networking Platforms

I got this RAM to upgrade my Synology NAS from it's factory installed 4GB to 64GB. This is a much cheaper way to upgrade the RAM than buying Synology RAM and works just as well. It is ECC RAM, just like the factory RAM. It also allows for a full 64GB rather than the Synology stated limit of 32GB. I noticed a substantial improvement in NAS performance after installing this RAM. I'm very happy and will purchase A-Tech RAM again.

Works great in my Synology DS1821+, passes all memory tests and is fully available to all applications.

Received as advertised, functioning and recognized by the system.I bought this sticks to improve the set up on my Qnap TS-473a NAS and working perfectly.

I have ordered seven of the 2x32GB DDR4 RAM modules and they have all worked perfectly. No issues, easy to install and best bang for the buck. I have never heard of A-Tech before this purchase, but they are quality ram modules and my experience has been great! I plan on using them again in the future.

Installed this on my DS1621+ and I was expecting to get some kind of warning. But, I was wrong! THIS JUST WORKS. I did not get any warning or error. It's as if my Syno was oblivious of the brand.

Smooth as silk and hits advertised benchmarks on a Dell 7560. Would purchase again!

Worked flawlessly on the Synology 723+ !!!The system recognized the both A-TECH 16GB RAM modules immediately, showed 32GB as the total memory installed just after the first NAS boot and the most important, with no warning messages from DSM 7.2.An excellent product at a very good price!Thanks ATECH folks!

Installed and did a complete Memory Test and it passed with no errors! What more can I say, it just works! And, it is much less expensive than the other option!
