Samsung 4GB PC4-17000 DDR4-2133MHz ECC Registered Memory Module

The Samsung M393A5143DB0-CPB is a 4GB DDR4-2133MHz ECC Registered memory module built for servers that cannot afford instability. It meets the PC4 17000 specification and draws only 1.2 volts, helping data centers conserve power while keeping enough bandwidth for everyday virtualization, database, or file sharing workloads. A built-in register manages clock, command, and control signals so the memory controller sees a lighter electrical load, an advantage when you populate multiple DIMM slots.

Error correction is handled by an additional parity byte that travels with every data word. This ECC capability lets the system detect and correct single-bit faults on the fly and identify larger faults before they reach your applications. Administrators who value uptime in web servers, mail hosts, or small office NAS boxes often rely on this safeguard to avoid unplanned outages.

The module follows a single-rank 1Rx8 layout and fits the 288-pin RDIMM socket found on many Intel and AMD server motherboards. Installation is as simple as inserting the module, cycling the power, and letting the BIOS pick up the JEDEC compliant timings. Whether you are expanding an existing rack or replacing a failed DIMM in a branch office server, this Samsung part number offers a straightforward path to stable memory capacity.
