Works great in a Synology DS1621+
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.

Compatible with Synology DS NAS
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 great!
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.

Great product
A-Tech is the memory we buy when they meet the specification required by our systems. They are great, haven't had a single problem with any of them. We are now testing this ECC unbuffered variation of 32GB SODIMMs good for our high end Synology NASes-
