Server memory for enterprise workloads

This 16GB DDR3 registered DIMM adds ECC-protected capacity to compatible servers and workstations. The module runs at 1600 MHz with CL11 latency and a standard 1.50V supply. It suits administrators who need dependable memory expansion for virtualisation, database or multi-user environments.

Thermals and power in normal use

Registered buffering reduces electrical load on the memory controller, helping stability under sustained server workloads. Standard 1.50V DDR3 voltage keeps power draw predictable within typical platform limits. No active cooling is required on the module itself; system airflow handles dissipation.

Upgrade path and when it matters

This module replaces Samsung M392B2G70BM0-CK0, M392B2G70DM0-CK0, M393B2G70BH0-CK0, M393B2G70CB0-CK0, M393B2G70DB0-CK0, M393B2G70EB0-CK0 and M393B2G70QH0-CK0 parts. The jump is worth it when ECC RDIMM slots are free and workloads exceed current memory capacity. It is not for systems that require unbuffered UDIMMs or a different DDR generation.

Questions about this item

How do I install this 240-pin DDR3 RDIMM in my server, and what step do people often miss?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips lock, then verify in BIOS that the 16GB module is detected at 1600 MHz with ECC active.

What maintenance or replacement will this 16GB DDR3-1600 RDIMM need over its service life?

No scheduled maintenance is required; keep air intakes clean so the 1.5V module stays cool, and replace only if memory diagnostics report correctable ECC errors rising or an uncorrectable error occurs.

What is the first limit that appears when this CL11 2Rx4 registered DIMM runs under sustained heavy load?

The registered buffer adds one cycle of latency, so sustained throughput tops out at the rated PC3-12800 bandwidth before the memory controller becomes the bottleneck.
