This DDR4-3200 Registered ECC RDIMM is engineered for server platforms handling virtualization, in-memory databases, and mission-critical workloads where data integrity is non-negotiable. Its dual-rank organization and ECC error correction deliver stable signal integrity and seamless correction of single-bit errors, ensuring reliable operation at 1.2V even under sustained memory-intensive loads.
1. ECC error correction scrubs single-bit errors in real time, preserving data integrity for financial ledgers and in-memory databases where even a silent bit-flip is unacceptable.
2. The registered clock driver buffers command and address lanes, allowing servers to fully populate all DIMM slots without sacrificing signal quality during large-scale virtualization.
3. A 32-gigabyte module footprint raises memory density per channel, letting operators host more virtual machines per node without triggering performance-sapping disk swap.
4. Dual-rank interleaving overlaps bank accesses to keep the memory pipeline fed, sustaining throughput when concurrent enterprise applications hammer the controller with requests.
5. 3200 megatransfers per second turn into a peak 25.6 GB/s channel bandwidth, slashing execution time for in-memory analytics and frequently accessed hot datasets.
In the data center, memory choice directly impacts uptime and throughput. The Samsung M393A4K40EB3-CWETY, a 32GB DDR4-3200 Registered ECC DIMM, delivers four crucial features that solve real operational challenges. First, ECC error correction continuously detects and fixes single-bit errors, preventing silent data corruption that can crash virtualization clusters hosting dozens of VMs. Second, the Registered buffer stabilizes signal paths, letting you fully load all memory channels with high-density modules without stability loss—a must when scaling in-memory databases like SAP HANA. Third, Dual Rank organization interleaves memory banks to boost bandwidth under parallel access, accelerating query responses in large datasets. Fourth, a 3200MT/s transfer speed with CL22 latency supplies the consistent high throughput needed for real-time analytics. For IT managers running virtual farms or demanding in-memory applications, this RDIMM translates into hardened data integrity, maximum population scalability, and tangible performance gains where it matters most.
This 32GB DDR4-3200 ECC Registered DIMM with dual-rank and CL22 targets enterprise servers. Below are capacity planning guidelines for three core scenarios.
General Virtualization
Install one DIMM per channel to sustain 3200 MT/s. Eight 32 GB RDIMMs in a 16-channel server give 256 GB, perfect for many VMs. Add a second DIMM per channel to reach 512 GB, accepting a slight speed reduction. Ensure identical modules across channels for stability.
In-Memory Database
A 2DPC layout fills 24 slots with 768 GB; speed typically falls to 2933 MT/s, which is still acceptable for large in-memory databases. Use memory interleaving and identical dual-rank DIMMs to minimize latency variations. Configure NUMA to keep data local when possible.
High-Performance Computing (HPC)
For peak bandwidth, use 1DPC—16×32 GB yields 512 GB at 3200 MT/s, eliminating interleaving penalties. This suits memory-intensive simulations. Keep all DIMMs identical and avoid mixing ranks for deterministic throughput. Also balance workloads across NUMA nodes.
Validated server memory: rigorously tested, compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10 Plus, Lenovo ThinkSystem SR650 V2.
Q: Can I mix this M393A4K40EB3-CWETY with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended in servers. It can cause stability issues, reduced performance, or POST failures. Always use identical modules for guaranteed compatibility.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-3200 ECC Registered RDIMM is compatible with servers supporting DDR4-3200 RDIMM, such as platforms based on Intel Xeon Scalable (2nd Gen or newer) or AMD EPYC 7002/7003 series.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate memory channels symmetrically per your server’s manual. Typically, start with the farthest slot from the CPU within each channel. Follow the specific population sequence for balanced memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This ECC Registered server memory runs at JEDEC standard speeds (DDR4-3200 CL22). It does not support XMP profiles or overclocking, as stability and data integrity are critical in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. Enterprise-class Samsung RDIMMs have very low failure rates (typically <0.2% AFR) under standard operating conditions, ensuring reliable long-term operation.
