This Samsung DDR4-2133 Registered DIMM with ECC is purpose-built for server platforms, delivering the data integrity essential for virtualization, in-memory databases, and mission-critical enterprise workloads. Its dual-rank x8 organization and registered signal buffering enhance signal stability and memory channel efficiency, enabling reliable operation at CL15 latency in dense, multi-DIMM configurations.
1. ECC protection detects and corrects single-bit errors in real time, dramatically reducing the risk of silent data corruption during long-running financial transactions or database operations.
2. Registered signal buffering enhances command and address integrity, enabling servers to maintain stability across fully loaded memory channels in 24/7 virtualization clusters.
3. Dual Rank x8 architecture enables bank interleaving that keeps memory pipelines saturated, ensuring consistent throughput under heavy multi-tenant workloads.
4. A 16GB module density offers the ideal granularity for balancing virtual machine density and memory headroom in scale-out cloud computing nodes.
5. 1.2V ultra-low operating voltage cuts per-DIMM power consumption, directly lowering cooling demands and energy costs in dense rack deployments.
The Samsung M393A2K43BB1-CPB is a 16GB DDR4-2133 Registered DIMM engineered for enterprise servers, where data integrity and unwavering uptime are non-negotiable. Its ECC technology actively corrects single-bit memory errors caused by cosmic radiation or electrical noise, directly preventing silent data corruption in mission-critical financial transaction databases where a flipped bit could miscalculate balances. The Registered signal buffer isolates the memory controller from excessive electrical loading, enabling you to populate all DIMM slots without compromising clock signal stability—this is essential when scaling a VMware virtualisation cluster to host dozens of VMs on a single node, maintaining smooth live migrations and consistent response times under heavy consolidation. Meanwhile, the dual-rank x8 organisation interleaves access across two internal rank groups, yielding higher sustained bandwidth and lower latency compared to single-rank modules. In an in-memory analytics engine like SAP HANA, this means faster aggregations on large datasets and snappier query performance, keeping your business intelligence workflows productive. Operating at a low 1.2V, the module also keeps thermal overhead in check across densely packed 1U and 2U rack servers, preserving reliability in environments where every watt saved reduces cooling strain and extends hardware longevity. Together, these attributes translate into a server memory foundation that protects your data, scales with your virtual workloads, and accelerates the real-time insights your organization depends on.
General Virtualization
For consolidated VM environments, install these 16 GB dual-rank RDIMMs evenly across all memory channels of each processor. One DIMM per channel in a typical dual-socket server delivers 256 GB, ideal for moderate density; populating two per channel scales to 512 GB for heavier workloads without sacrificing balanced bandwidth.
In-Memory Database
Maximize node capacity by filling every slot with identical M393A2K43BB1-CPB modules, targeting 512 GB or more. Their registered ECC and dual-rank design offer the low latency and data integrity required for sustained, high-throughput in-memory processing of large datasets.
High-Performance Computing
Memory bandwidth is critical—populate channels symmetrically, usually one 16 GB DIMM per channel, to achieve peak throughput. This evenly distributes capacity across CPU memory controllers, preventing NUMA bottlenecks during parallel simulation, modeling, and analytics workloads.
Rigorously tested for compatibility with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this M393A2K43BB1-CPB with other memory modules of different brands or speeds?
A: Mixing is not recommended. For server environments, identical modules (same MPN and batch) ensure reliable operation, proper ECC functionality, and avoid potential instability caused by unmatched timings or ranks.
Q: Is this memory compatible with my system?
A: It is designed for servers supporting DDR4-2133 ECC Registered DIMMs, such as Intel Xeon E5-2600 v3/v4 or select AMD EPYC platforms. Please verify against your motherboard’s qualified vendor list to confirm compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server manual’s population guidelines. Typically, install identical DIMMs per channel, starting with the farthest slots from the CPU, to enable balanced interleaving and maximum memory bandwidth while maintaining rank consistency.
Q: Does this module support overclocking or XMP profiles?
A: No. As a JEDEC-compliant server RDIMM, it does not support overclocking or XMP. It operates at fixed 2133MHz CL15 timings, prioritizing data integrity and 24/7 stability over performance variability.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. Typical failure rates are very low due to rigorous server-grade screening and ECC resilience, making it highly reliable for mission-critical workloads under continuous operation.
