Designed for server platforms handling memory-intensive workloads such as virtualization and in-memory databases, this 32GB DDR4-3200 Registered ECC module ensures data integrity and system stability under continuous operation. Its dual-rank x8 organization leverages interleaving for improved bandwidth efficiency, while the CL22 latency and 1.2V low-voltage operation deliver a balance of responsive error-corrected performance and energy savings.
1. Error-correcting code memory safeguards against data corruption, indispensable for mission-critical server applications where even a single-bit error could compromise financial accuracy or system uptime.
2. Registered DIMM architecture buffers command and address signals, stabilizing high-density memory configurations and enabling seamless scaling to terabyte-scale footprints for demanding hypervisors.
3. This module's generous capacity supports dense virtualization and large in-memory databases, maximizing workload consolidation per server node without expanding physical footprint.
4. High memory bandwidth meets the demands of contemporary multi-core server CPUs, accelerating data-intensive tasks such as real-time analytics and cryptographic processing.
5. Dual rank design interleaves memory bank accesses to keep channels fully utilized, delivering predictable low-latency throughput for latency-sensitive enterprise workloads.
When every transaction must be accurate and every virtual machine demands unwavering stability, the Samsung M393A4G43AB3-CWE server memory module transforms raw specifications into business resilience. This 32GB DDR4-3200 RDIMM leverages ECC to silently correct single-bit errors in real time, a critical defense against silent data corruption that can crash virtualized clusters or poison financial records. In a dense virtualization environment running dozens of VMs per host, the registered signal architecture buffers command and address lines, allowing the platform to populate all channels with dual-rank modules without sacrificing signal integrity—meaning you can confidently scale to 512GB or 1TB and maintain 3200MT/s throughput. For in-memory databases like SAP HANA or Redis, that dual-rank x8 design enhances bandwidth utilization by interleaving accesses across internal ranks, shrinking query latencies under heavy concurrency. The 1.2V operating voltage further reduces thermal load across a fully populated server, improving energy efficiency in data centers where every watt counts. This isn't just about specs; it’s about upholding uptime SLAs and accelerating the insights your business runs on.
General Virtualization
This 32GB DDR4-3200 RDIMM is ideal for virtualized environments running multiple VMs with moderate resource allocations. Deploy six to eight identical modules in a dual-socket server to reach 192–256 GB, ensuring balanced memory population across all memory channels for optimal throughput. ECC protection guards against data corruption, which is critical when hosting diverse tenant workloads on shared hardware.
In-Memory Database
For in-memory databases like Redis or SAP HANA, populate all memory channels with dual-rank x8 modules to maximize bandwidth and capacity. A configuration of 16 modules (512 GB total) per node delivers low-latency access and consistent CL22 timings under sustained read/write pressure. The registered buffer stabilizes signal integrity, allowing dense 128 GB+ deployments without compromising reliability.
High-Performance Computing (HPC)
In HPC clusters, pair six or eight of these 3200 MT/s RDIMMs per compute node to saturate memory bandwidth for MPI-based simulations. Dual-rank design boosts data rate per channel, while ECC corrects single-bit errors during multi-day job runs. Stick to homogeneous module sets to avoid speed negotiation penalties and maintain predictable runtimes across the cluster.
Rigorously tested, this server memory ensures compatibility with Dell R750, HPE DL380 Gen10 Plus, Lenovo SR650 V2, and more.
Q: Can I mix this M393A4G43AB3-CWE with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for registered ECC server memory. It may cause signal instability, degrade reliability, and invalidate platform validation. Always populate identical part numbers for mission‑critical environments.
Q: Is this memory compatible with my system?
A: This DDR4‑3200 RDIMM is compatible with server platforms supporting registered ECC DDR4, such as Intel Xeon Scalable (Gen 2/3) or AMD EPYC 7002/7003 series. Please verify your motherboard QVL and CPU memory‑controller capabilities.
Q: What is the recommended DIMM population order for optimal performance?
A: Install identical DIMMs in balanced symmetrical channels per CPU socket. Typically, populate white‑tabbed slots first (e.g., A1, B1, C1, D1) to enable 4‑channel interleaving. Observe server‑specific population guidelines for maximum throughput and fault‑tolerance.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC‑compliant registered ECC module operating at fixed 3200 MT/s with CL22 timings. Overclocking and XMP are intentionally disabled to ensure data integrity and 24/7 stability in server workloads.
Q: What warranty and typical failure rate can I expect?
A: The module includes a one‑year warranty. Field annualized failure rates are typically below 0.1%, reflecting rigorous Samsung screening, advanced error‑correcting code (ECC), and burn‑in testing that deliver enterprise‑grade reliability.
