Synology DDR4 2666 MHz SODIMM Non-ECC Reviews

Great Product

Great product, great seller, quick shipping, and great price

It's just an SO-DIMM--but "Synology"

By Richard

Works as expected in a DS225+. It's just an expensive 4GB 2666MHz DDR4 SO-DIMM; with specs common over half a decade ago. On the plus side, Synology Support won't be able to use it as an excuse for any DSM issues.
