A-Tech 64GB Kit (2x32GB) 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.

Wrong packaging? Misplaced labels? Or deliberate cheating? Not sure. I purchased 2 x 16GB RAM and installed in Synology NAS. System shows only 2 x 4GB

So far working really well in my Synology DS1821+. No issue, no configuration, no fuss. They were detected as soon as the NAS booted up with them in it

Used to expand the memory on my DS1823XS+, worked like a charm with compatibility script commonly used on the web. The NAS was able to address the full 64GB.

Works on my Synology DS1821+ Been working since April 2024 without any problems.
