Samsung 16GB DDR4 DIMM 288-pin 3200 MHz PC4-25600 Registered Memory Module

The Samsung M393A2K40EB3-CWE is a 16 GB DDR4 Registered DIMM that adds dependable, high-speed memory capacity to servers equipped with 288-pin RDIMM slots. It operates at 3200 MHz, delivering the bandwidth required for data-intensive tasks while maintaining a low 1.2 V operating voltage to help manage power consumption in dense server racks.

This module uses an onboard register that buffers command and clock signals before they reach the DRAM chips. By reducing electrical loading, the register improves stability when multiple modules populate each channel, a common requirement in dual-processor motherboards or systems that run two DIMMs per channel. ECC with 8-bit parity is built in, allowing the memory to detect and correct single-bit errors automatically so critical workloads continue without data corruption.

With a JEDEC-compliant design and CL22 latency, the module integrates smoothly into servers that follow industry standards. Its single-rank x4 organization helps balance capacity, performance, and thermal characteristics, making it suitable for virtualization hosts, database servers, and high-performance computing nodes where consistent uptime is essential.

Installation is straightforward: insert the module into any DDR4 RDIMM slot that supports 3200 MHz memory. It is designed for servers rather than desktop PCs, and it works especially well in platforms that benefit from ECC protection and registered signal buffering.
