Samsung Server RDIMM Upgrade

This 16 GB DDR4 3200 CL22 module is built for Samsung servers and workstations that require ECC registered memory. The 2Rx8 organisation and 1.20 V operation match the original M393A2K43DB3-CWE specification for drop-in compatibility. IT teams use it to expand capacity in mission-critical systems without changing platform firmware.

Registered ECC Slot Requirements

The stick fits a standard 288-pin DDR4 RDIMM socket and needs a motherboard that supports registered ECC operation. It cannot be used in consumer desktop boards that accept only unbuffered non-ECC modules. One module occupies a single slot, leaving remaining channels free for further identical sticks to reach the platform maximum.

Thermals and Power Profile

Operating at 1.20 V with no heat spreader, the module runs within standard DDR4 thermal limits inside server chassis airflow. Registered buffering adds negligible latency while maintaining signal integrity at full 3200 MT/s speed. Power draw stays low per stick, helping dense configurations stay within chassis power budgets.

Questions about this item

Does the CL22 latency limit throughput when the server runs sustained workloads?

CL22 is the rated CAS latency at 3200 MT/s; sustained throughput depends on the memory controller and workload pattern.

How much heat does the 1.20 V module produce during all-day operation without a heat spreader?

The module runs at standard DDR4 voltage and relies on chassis airflow; ensure the server has adequate cooling for registered DIMMs.

What motherboard feature must already be present for this 288-pin RDIMM to function?

The board must support DDR4 registered ECC memory with 2Rx8 organization.
