Designed specifically for enterprise server platforms, this Samsung 32GB DDR4-3200 Registered DIMM with error-correcting code (ECC) is optimized for memory-intensive workloads such as virtualization, in-memory databases, and mission-critical applications where data integrity is paramount. Its dual-rank x4 organization maximizes bank-level parallelism for sustained throughput, while the registered signal type ensures stable operation under high-capacity, multi-DIMM configurations.
1. Registered signal type enables stable operation with large memory populations, allowing dense server configurations to scale up for heavy virtualization without compromising signal integrity.
2. ECC error correction actively detects and corrects single-bit memory faults in real time, preserving data integrity in transactional databases and financial workloads where silent data corruption is unacceptable.
3. Dual Rank x4 organization maximizes memory bandwidth utilization by interleaving access across ranks, translating directly into smoother performance for virtual machines under simultaneous heavy loads.
4. 32GB capacity per module hits a versatile density sweet spot, letting data centers pack substantial memory into 2-socket servers for moderate in-memory analytics without wasting costly capacity.
5. 3200MHz frequency elevates memory throughput to 25.6 GB/s, accelerating real-time data ingestion and caching tiers so latency-sensitive services stay responsive under peak traffic.
The Samsung M393A4K40DB2-CWEBY is a 32GB DDR4-3200 RDIMM purpose-built for enterprise servers, where unplanned downtime and data corruption are simply not an option. In a dense virtualization cluster hosting dozens of VMs per node, its ECC engine continuously detects and corrects single-bit memory errors caused by background radiation or cosmic particles. This means a flipped bit will never silently corrupt a financial transaction or compromise a customer database, directly protecting revenue and trust. Meanwhile, the registered signal buffer stabilizes the command and address buses, enabling the server to populate all memory channels with high-capacity modules without electrical loading issues that cause boot failures. When running an in-memory database like SAP HANA or a Redis cluster, the dual rank x4 organization interleaves memory banks for significantly higher sustained bandwidth, slashing query latency during simultaneous read/write storms. Combined with a 3200MT/s transfer rate and a true 1.2V low-power profile, this module delivers the throughput and energy efficiency your data center demands under 24/7 operation, turning raw specifications into tangible business continuity.
General Virtualization
For general virtualization hosts, balance density and cost by deploying six to eight of these 32GB RDIMMs across dual-socket platforms, yielding 192–256GB total memory. Populate one DIMM per memory channel to maintain balanced memory access while leaving room for future expansion. ECC and registered buffering ensure virtual machine stability under mixed workloads.
In-Memory Database
Maximize capacity and interleaving for in-memory databases like SAP HANA or Redis by fully populating all channels with identical 32GB RDIMMs—typically 12 or 16 modules per server. Dual-rank x4 construction delivers superior signal integrity and bandwidth, which is critical for large dataset scans and high transaction throughput. Configure memory sparing or mirroring if absolute uptime is mandated.
High-Performance Computing
Achieve peak memory bandwidth in HPC clusters by installing one 32GB RDIMM per channel across all available channels, typically eight modules per node, to leverage full memory interleaving. The 3200MT/s speed and CL22 latency provide a solid balance between capacity and data rate for simulation and modeling codes. Scale horizontally with identical configurations across nodes to avoid performance variance in parallel jobs.
Rigorously tested server memory, compatible with Dell R750, HPE DL380 Gen10+, Lenovo SR650 V2, and more.
Q: Can I mix this M393A4K40DB2-CWEBY with other memory modules of different brands or speeds?
A: Mixing modules is not recommended in servers. Identical part numbers ensure consistent ECC and registered operation. Using different brands or speeds may cause stability issues and is unsupported.
Q: Is this memory compatible with my system?
A: This RDIMM is designed for servers using Intel Xeon Scalable or AMD EPYC platforms that support DDR4-3200 Registered ECC memory. Verify your board's qualified vendor list for this 32GB Dual Rank x4 module.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-socket servers, populate identical DIMMs per channel following the platform’s memory slot numbering, usually starting with white slots first. Balanced interleaving across memory channels ensures maximum bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a JEDEC-compliant server DIMM operating at fixed 3200MT/s with CL22. Overclocking and XMP are not supported as registered ECC memory prioritizes reliability over speed adjustments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-grade registered DIMMs have very low annualized failure rates, typically below 0.5%, thanks to extensive manufacturing testing and ECC protection.
