Supports unregistered/unbuffered ECC. Stays cool at 1.20V and auto detected 3200 MHz. Has 2Rx8 configuration rather than the slower 1Rx16 like some other memory options. No issues detected in MemTest86.

I purchased these for an Asrock X470D4U server mobo running a Ryzen 7 3700X CPU with ESXi v7. The QVL does list the KSM26ED8/16ME so I figured I'd gamble. The server is still in test, not production, but I've had no issues so far. The pricing of 64GB (2x32GB) is a bit better than 64GB (4x16GB). And I have some spare slots for more memory.

Affordable, high-density, ECC, unbuffered RAM. Was disappointed how most ECC RAM you find is registered and therefore incompatible with a lot of systems. Was happy to find this unbuffered stuff. Booted up and tested fine after several runs of memtest86. Happy to have 64GB of RAM thanks to these sticks.

Works with DS2419+. Less than 5 minute initial boot with (the x2 sticks). Ordered a different set for cheaper, dont fall for that. They didn't work. These worked on first plug-in. No issues, quick boot. Much cheaper than "Synology" ram.

I got a z210 from an employee surplus program my work used to have years ago. Came with a Xeon and 8 GB of RAM (4x2GB). I use it as my test box. I wanted to build a small home lab with it instead of spending the money to upgrade and now I can get a little more life out of it. It already flew with a cheap SSD and 8 GBs of RAM with any linux distro.
