This 32GB DDR4-3200 RDIMM with ECC and a dual-rank x4 organization is purpose-built for enterprise servers running memory-intensive workloads such as virtualization and in-memory databases, where end-to-end data integrity is critical. The registered signal buffering combined with ECC error correction and the dual-rank configuration maximizes signal stability and memory interleaving bandwidth, ensuring reliable 24/7 operation in dense multi-DIMM server environments.
1. Registered signal buffering stabilizes address and command lines under heavy DIMM population, making large-scale server deployments resilient against signal degradation and command errors.
2. ECC protection actively detects and corrects single-bit errors in real time, safeguarding virtualized databases and financial transactions from silent data corruption.
3. Dual Rank x4 organization interleaves page accesses to keep the memory channel saturated, delivering consistent throughput for dense VM clusters under mixed workloads.
4. The 32GB capacity per module maximizes memory density per channel, enabling higher virtual machine counts without sacrificing available DIMM slots for future scaling.
5. 3200 MT/s data rate accelerates in-memory analytics and caching layers, shrinking response times for concurrent user queries in data-center applications.
The Samsung M393A4K40DB3-CWEC0 is a 32GB DDR4-3200 Registered ECC DIMM purpose-built for data centers. Its four standout attributes—ECC error correction, registered buffering, dual-rank x4 design, and 3200MT/s speed—translate directly into critical real-world benefits. ECC is your first line of defense against silent data corruption. In a virtualized cluster, a single uncorrected bit flip could crash multiple VMs or corrupt a financial transaction; this module detects and fixes those errors on the fly, safeguarding uptime and accuracy. The registered buffer stabilizes command and address signals, enabling you to populate all DIMM slots for massive 1TB+ memory footprints without signal degradation—essential for memory-hungry in-memory databases like SAP HANA or dense VMware farms. Meanwhile, the dual-rank x4 architecture amplifies bank interleaving, delivering higher sustained bandwidth and accelerating concurrent virtual machine access. Combined with 3200MT/s, it ensures your analytics queries return results faster and your virtual infrastructure packs more tenants per server. Together, these features build a resilient, high-density platform where data integrity, scale, and performance are non-negotiable.
Server Memory Identified: The specifications (ECC, Registered, Dual Rank x4, RDIMM, 288-pin) confirm this is a DDR4-3200 server-grade module, optimized for stability and multi-DIMM configurations in enterprise environments.
General Virtualization
For virtualized clusters running multiple VMs, populate six or eight of these 32GB RDIMMs per dual-socket host to achieve 192–256GB total capacity. This provides ample memory for overcommitting resources while maintaining balanced NUMA access across both processors. Configure identical DIMMs in each memory channel to maximize bandwidth and avoid performance penalties.
In-Memory Database
Low-latency databases like Redis or SAP HANA benefit from large, fault-tolerant memory pools. Install a full set of 12 or 16 modules per quad-channel server, reaching 384–512GB, to keep entire datasets resident. Use dual-rank x4 DIMMs to leverage higher bank-level parallelism, and always pair with identical ECC RDIMMs to guard against data corruption.
High-Performance Computing
HPC workloads demand maximum throughput per core. Populate one DIMM per channel across all available channels (typically 8 per socket) for peak memory bandwidth without exceeding the sweet spot of one DPC at 3200MT/s. The 32GB capacity per module offers a strong balance, enabling 256GB per node while sustaining full-speed signaling and keeping power budgets in check.

Q: Can I mix this M393A4K40DB3-CWEC0 with other memory modules of different brands or speeds?
A: Mixing server RDIMMs of different brands or speeds is strongly discouraged. It can cause instability, ECC errors, or forced downclocking. For guaranteed uptime, use identical Samsung M393A4K40DB3-CWEC0 modules matching rank and capacity.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-3200 ECC Registered RDIMM is designed for Intel Xeon Scalable and AMD EPYC server platforms with 288-pin slots. Please confirm your motherboard's QVL lists support for dual-rank x4 modules at this speed.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s DIMM population guide. Typically, fill identical modules per channel starting from the farthest slot from the CPU. Balanced channel loading ensures optimal bandwidth and maintains NUMA symmetry.
Q: Does this module support overclocking or XMP profiles?
A: No. This module adheres to JEDEC standards and does not support overclocking or XMP profiles. Its registered design and ECC function prioritize data integrity over performance tuning, making it ideal for stable server operation.
Q: What warranty and typical failure rate can I expect?
A: This Samsung memory includes a 1-year warranty. Enterprise RDIMMs like M393A4K40DB3-CWEC0 exhibit very low annualized failure rates, typically under 0.5%, ensuring dependable performance in 24/7 server environments.
