The Samsung M391B5673CH0-CH9 is a genuine 2GB DDR3 memory module. It runs at 1333MHz on the PC3-10600 standard. It uses ECC Unbuffered design with a dual-rank, 240-pin layout.
This module checks memory constantly while the system runs. It fixes small errors before they cause a crash or data loss. As an unbuffered module, it targets workstations rather than full rack servers. It carries a CL9 latency rating and runs on standard 1.5V power.
Unbuffered ECC memory at this speed fits many Dell Precision and HP Z-series workstations. Some small office towers use it too. It does not fit registered memory slots, which most rack servers require instead. Check your exact model first.
This module is refurbished, not new. Each one is cleaned and tested first. This confirms it works before it gets listed. The chips are genuine Samsung, not a generic substitute. A 30-day warranty covers every order.
This module works well for replacing a failed 2GB stick in an existing workstation. It also adds working memory to a system that slows down under multiple open programs. A matched pair keeps dual-channel setups running evenly.
Check your system manual or manufacturer support page for the exact memory type. Installing the wrong type simply will not be recognized by the system.
For general office and light workstation tasks, yes. Heavier workloads benefit more from higher speeds where the system supports them.
