This ECC Registered DDR4-3200 RDIMM is engineered for enterprise servers and data-center workloads, delivering the data integrity and capacity scalability required by virtualization clusters, in-memory databases, and mission-critical applications. Its dual-rank configuration maximizes bank-level parallelism for improved throughput, while the registered signal buffering and CL22 latency ensure stable, high-density operation across multiple DIMMs per channel.
1. ECC protection detects and corrects single-bit memory errors in real time, preserving data integrity for mission-critical enterprise workloads where even silent corruption is unacceptable.
2. Registered signal buffering stabilizes command and address lines across high-density server configurations, enabling reliable operation with fully populated memory channels under heavy virtualization loads.
3. Dual Rank design interleaves access across two internal ranks per DIMM, boosting effective bandwidth to sustain predictable database response times during simultaneous query spikes.
4. 32 GB capacity per module maximizes memory footprint in standard server nodes, allowing more virtual machines per physical host and deferring costly hardware scale-out.
5. 3200 MT/s data rate accelerates in-memory analytics and transactional processing, reducing latency windows that directly translate to faster business insights and service delivery.
The Samsung M393A4G43AB3-CWEBQ is a server-grade DDR4 RDIMM, and its four standout characteristics directly resolve the most painful realities of enterprise infrastructure. In a dense virtualization cluster, where a single host runs dozens of VMs, a random bit flip in memory can silently corrupt guest operating systems or transaction ledgers. The integrated ECC engine catches and corrects these single-bit errors on the fly, turning a potential multi-VM outage into a non-event and safeguarding data integrity for your critical workloads. Meanwhile, the Registered buffer stabilizes the command and address signals across fully populated 24-slot servers, so you can confidently scale to terabyte-class capacities without boot failures or intermittent instability—a necessity when consolidating heavy database instances. Dual Rank organization becomes vital the moment you deploy an in-memory database like Redis or SAP HANA. By interleaving accesses across two internal ranks, this module keeps the memory pipeline saturated, delivering measurably lower query latency and faster transaction commits because the processor spends less time stalled. The 3200MT/s speed ensures that bandwidth keeps pace with modern multi-core Xeon CPUs, preventing memory bottlenecks during real-time analytics and AI inference. What it means for you is uncompromising uptime, higher VM density, and accelerated data throughput in every rack.
General Virtualization
This RDIMM is ideal for dense virtualization hosts. Populate six or eight identical 32 GB modules across balanced memory channels to deliver 192–256 GB of capacity, allowing dozens of modest VMs without overcommitting memory. Pair it with a server platform that supports registered ECC to maintain data integrity under constant multi-tenant workloads.
In-Memory Database
For in-memory databases like Redis or SAP HANA, capacity and reliability are paramount. Equip all memory channels with these dual‑rank 32 GB DIMMs to reach 512 GB or more, ensuring the entire dataset fits in RAM. The ECC and registered design prevent silent data corruption during high‑throughput caching and transactional processing.
High-Performance Computing (HPC)
HPC clusters demand both bandwidth and error resilience. Install one DIMM per channel across eight or twelve slots to maximize memory bandwidth, leveraging the 3200 MT/s speed and dual‑rank interleaving. The registered ECC architecture guards long‑running simulation jobs against single‑bit errors, while 32 GB per module supplies enough capacity per node for memory‑bound scientific workloads.
Validated for strict compatibility with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650 V2.
Q: Can I mix this M393A4G43AB3-CWEBQ with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is strongly discouraged in server environments. For guaranteed stability and ECC functionality, use identical modules with the same Samsung part number, as mismatched timings or ranks can lead to system errors.
Q: Is this memory compatible with my system?
A: This 32GB DDR4‑3200 Registered ECC RDIMM is compatible with servers based on Intel Xeon Scalable or AMD EPYC platforms that support DDR4 Registered memory. Always check your motherboard or system Qualified Vendor List for M393A4G43AB3-CWEBQ to ensure compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server motherboard manual. Optimally, populate identical DIMMs evenly across all memory channels, starting with the first slot of each channel, to achieve balanced multi‑channel interleaving and maximize memory bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server‑grade JEDEC‑compliant RDIMM with ECC, engineered for maximum stability and data integrity. It does not support overclocking or XMP profiles, as its primary function is reliable error correction in mission‑critical operations.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1‑year warranty. As an enterprise‑class Samsung RDIMM built for 24/7 operation, it exhibits an extremely low annualized failure rate (typically below 0.5%), ensuring dependable long‑term reliability for critical workloads.
