This Samsung 2GB memory module is genuine Samsung equipment. The part number is M391B5673DZ1-CG8. It uses an Unbuffered ECC design, often called UDIMM. This is a different memory type than Registered ECC. It fits a different set of systems. This module runs at 1066MHz. It follows the PC3-8500 standard.
This module has ECC support and a dual-rank design. ECC catches and corrects memory errors before they crash your system. Dual-rank packs more addressable memory into a single slot. It carries a CL7 latency rating for steady performance. Every unit is tested and cleaned before it ships. It performs like new.

So do workstation lines such as Dell Precision and HP Z series. This module will not work in dual-socket rack or blade servers. Those systems need Registered ECC instead. Please check your exact model before ordering.
