Samsung's 16GB DDR4-3200 RDIMM module, part number M393A2K43DB3-CWE, is purpose-built for Intel Xeon Scalable processors (3rd Gen and later) and fits into the memory channels of dual-socket and multi-socket server configurations typical in enterprise data centres across the GCC region. This registered DIMM operates at 3200 MT/s, a speed that balances performance delivery with thermal stability in dense server environments where consistent uptime matters more than peak frequency. The M393A2K43DB3-CWE sits comfortably in the mainstream capacity tier—neither oversized nor underpowered—making it the default choice for organisations building or refreshing general-purpose compute clusters.

The registered architecture is what separates this module from desktop or workstation memory. A register on the M393A2K43DB3-CWE isolates the control signals from the DRAM chips themselves, reducing electrical load on the processor's memory controller and allowing server platforms to populate more DIMMs per channel without signal integrity issues. Samsung engineered this module with ECC (error-correcting code) enabled, a non-negotiable requirement in any production data centre. Silent bit flips in unprotected memory can corrupt databases, corrupt application state, or trigger intermittent failures that consume weeks of engineering time to diagnose. The 1.2V operating voltage keeps power consumption modest—important when you're multiplying this across 24, 48, or even 96 DIMM slots in a single chassis.

Infrastructure teams purchasing the M393A2K43DB3-CWE tend to be storage architects and systems administrators who spec out server builds for either virtualisation platforms (VMware, Hyper-V), high-performance databases (SQL Server, PostgreSQL), or AI inference workloads that demand low-latency memory access. The 16GB capacity per DIMM is the pragmatic middle ground: enough to avoid excessive swapping, small enough that mixed-size configurations don't force unnecessary waste. With a two-rank (2Rx8) organisation and CAS latency of CL22, this Samsung module delivers predictable latency profiles across sequential and random access patterns. The part number M393A2K43DB3-CWE carries the PC4-25600R designation, confirming its rated bandwidth ceiling of 25.6 GB/s per channel—sufficient for workloads that don't demand the exotic clock speeds of gaming rigs or overclocked workstations.

Installation and validation are straightforward. The M393A2K43DB3-CWE is immediately recognised by BIOS on compatible Xeon platforms; no firmware tweaking required. Samsung backs these modules with standard enterprise warranties, and the brand's consistency in manufacturing means you'll rarely encounter JEDEC compliance surprises or undocumented voltage margining issues. For data-centre operators managing thousands of servers, that predictability translates to fewer RMA cycles and lower total cost of ownership. The module slots into standard 19-inch rack-mount servers from Dell, HPE, Lenovo, and Supermicro—the vendors that dominate enterprise purchasing across Asia and Europe. Whether you're deploying a single test rig or populating a new server pod, the M393A2K43DB3-CWE offers the reliability profile that justifies its place in production environments.
