Designed for enterprise-class servers, this DDR4-2133 Registered ECC DIMM ensures data integrity in virtualized environments and memory-intensive databases with its error-correcting code and registered signal buffering for stable multi-DIMM operation. The dual-rank x4 configuration and CL15 latency balance capacity and access parallelism, making it ideal for workloads that demand high reliability and consistent throughput under heavy memory loads.
1. ECC memory detects and corrects single-bit errors on the fly, safeguarding transactional databases from silent data corruption that could crash financial services or ERP workloads.
2. Registered signal type buffers the command and address lines, enabling servers to scale up to massive DIMM counts per channel without compromising signal integrity under fully populated configurations.
3. Dual Rank x4 organization interleaves memory accesses across two internal rank groups, maximizing sustained bandwidth for virtualized environments where dozens of VMs compete for I/O simultaneously.
4. DDR4 technology delivers a fundamental reduction in operating voltage and improved internal prefetch efficiency, translating directly to lower power bills in hyperscale data centers running thousands of nodes around the clock.
5. Sixteen-gigabyte capacity hits a density sweet spot that balances cost-per-gigabyte with ample headroom, letting cloud providers pack more containers or in-memory caches into a single host before requiring costly scale-out.
In the data center, uptime is everything. The Samsung M393A2G40DB0-CPB0Q 16GB DDR4-2133 RDIMM is a strategic asset. Its ECC technology provides a crucial shield against silent data corruption from bit flips. For a virtualized cluster running dozens of VMs, a single undetected memory error can cascade into crashes or data loss; ECC turns this risk into a non-event by detecting and correcting single-bit errors. Meanwhile, the registered buffer stabilizes the electrical load, enabling you to populate all memory channels without compromising speed. This is vital for in-memory databases like SAP HANA, where the dual-rank x4 organization interleaves data across two ranks, boosting bandwidth for real-time analytics. With a consistent 2133MT/s speed and CL15 latency, it delivers steady performance for these demanding workloads. Operating at 1.2V, this module reduces thermal footprint in dense racks, lowering cooling costs while delivering the reliability your mission-critical applications demand.
General Virtualization
For a typical dual-socket virtualized host, populate at least one 16GB RDIMM per memory channel to balance capacity and bandwidth. A six-channel platform per CPU benefits from six identical M393A2G40DB0 modules per processor (96GB per socket), delivering 192GB total for moderate VM density without wasting resources. Stick to identical dual-rank x4 DIMMs to maintain uniform interleaving and avoid performance penalties.
In-Memory Database
Maximize capacity and reliability by fully populating all channels with these 16GB registered ECC modules. In a two-socket server with three DIMMs per channel, installing 36 modules yields 576GB of low-latency DDR4-2133 memory, ideal for large in-memory datasets. The 1.2V operation and ECC protection ensure data integrity under constant heavy load, while the dual-rank design sustains command rate without excessive power draw.
High-Performance Computing
Configure one 16GB RDIMM per channel across all available memory controllers to achieve peak aggregate bandwidth. For instance, eight channels per node with one module each provide 128GB of capacity at the maximum supported speed, minimizing latency skew in tightly coupled MPI workloads. Use identical M393A2G40DB0 sticks in every slot to guarantee symmetric memory access, and leverage ECC to detect silent data corruption during long-running simulations.
Rigorously tested for server compatibility with Dell PowerEdge R730/R630, HPE ProLiant DL380 Gen9, and Lenovo System x3650 M5.
Q: Can I mix this M393A2G40DB0-CPB0Q with other memory modules of different brands or speeds?
A: Mixing this Samsung DDR4-2133 RDIMM with different brands or speeds is strongly discouraged. Inconsistent attributes may cause signal integrity issues and system instability in servers. Always use identical modules for validated configurations.
Q: Is this memory compatible with my server featuring Intel Xeon or AMD EPYC platforms?
A: This 16GB DDR4-2133 ECC Registered DIMM is compatible with Intel Xeon E5-2600 v3/v4 and AMD EPYC 7001 series platforms that support DDR4 RDIMM at 2133 MT/s. Always verify the system's Qualified Vendor List (QVL).
Q: What is the recommended DIMM population order for optimal performance on a dual-socket server board?
A: Populate memory channels symmetrically per CPU, starting with the farthest slot from the processor. For example, fill blue slots first with identical x4 Dual Rank RDIMMs to maximize interleaving and balanced loading.
Q: Does this RDIMM support overclocking or XMP profiles?
A: No. This module adheres to JEDEC-standard DDR4-2133 with ECC and registered buffering for reliability on server platforms. Overclocking and XMP profiles are not supported, as they compromise signal integrity.
Q: What warranty and typical failure rate can I expect with this Samsung memory?
A: This M393A2G40DB0-CPB0Q is covered by a one-year warranty. Samsung server-grade RDIMMs exhibit an annualized failure rate (AFR) typically below 0.5% under normal operating conditions, ensuring high reliability.
