16GB DDR4 ECC RDIMM for Servers

This 16GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It uses a registered 2Rx8 organisation and Samsung chipset for error-correcting stability. The 288-pin DIMM fits standard DDR4 server slots. It targets administrators upgrading compatible Samsung M393A2K43BB1-CPB or M392A2K43BB0-CPB configurations.

Registered DIMM Integration Requirements

The registered buffer reduces electrical load on the memory controller, allowing higher capacities per channel. Your motherboard must support DDR4 RDIMM topology and ECC functionality. Unbuffered consumer boards will not accept this module. The 1.2V standard voltage matches DDR4 server specifications without extra power tuning.

Sustained Workload Stability

ECC circuitry corrects single-bit errors during continuous operation, preventing silent data corruption. Registered signalling maintains signal integrity across fully populated channels under prolonged load. The CL15 timing and 2133MHz data rate deliver consistent throughput for virtualisation and database tasks. Modules are tested for reliability before shipment.

Preguntas sobre este artículo

Will the 2Rx8 rank configuration limit the number of modules I can populate per channel?

The 2Rx8 dual-rank design counts as two logical ranks per module; most server platforms allow up to eight ranks per channel, so you can typically install up to four of these 16 GB sticks per channel before hitting the rank limit.

Does the registered ECC design increase heat or power draw compared with unbuffered DDR4?

The register adds negligible power — the module runs at the standard 1.2 V DDR4 voltage — and because it operates at 2133 MHz CL15, thermal output stays within normal DDR4 limits for continuous server workloads.

My motherboard has 288-pin DDR4 slots; will this 262-pin module fit?

The spec lists a 262-pin form factor, which is a SO-DIMM layout, while your board uses 288-pin DIMM slots; the two are physically incompatible, so this module will not install in a standard server motherboard.
