This memory worked out of the box. It got detected as 5200MHz in my motherboard that didn't list it in the QVL. I was able to choose speed of 5600MHz in the BIOS and it worked without any glitches. Very good stick of RAM at a good price.

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.

Confirmed ECC was enabled/functional using commands in both Win10 and Ubuntu. HWiNFO64 also indicated ECC was enabled/functional as did PassMark's Memtest86. Used Memtest86 to test over a few days with ECC error injection enabled and had zero issues.
