## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great in a Synology DS1621+
*by R***N on March 26, 2024*

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 in my Synology NAS

### ⭐⭐⭐⭐⭐ Qnap Upgrade
