Designed for server-class workloads, this Samsung M393A2K43BB1-CRC0Y 16GB DDR4-2400 Registered DIMM leverages ECC and a dual-rank x8 organization to ensure data integrity and consistent performance under heavy memory access. Its registered signal type and 1.2V operating voltage make it ideally suited for dense virtualization clusters and in-memory database deployments where stability and energy efficiency are critical.
1. ECC detects and corrects single-bit errors on the fly, directly preventing silent data corruption in financial transactions or virtualized database workloads where data integrity is non-negotiable.
2. Registered signal buffering stabilizes command and address lines when populating high-density server boards, enabling reliable operation across dozens of DIMMs per CPU without signal degradation.
3. 16GB capacity per module allows a dual-socket server to comfortably provision hundreds of lightweight containers or multiple memory-hungry VMs within a compact footprint, optimizing consolidation ratios.
4. Dual Rank x8 organization leverages rank interleaving to sustain higher bandwidth utilization, reducing memory access latency spikes during simultaneous analytics queries across large in-memory datasets.
5. 2400MHz speed provides a balanced throughput foundation for mainstream enterprise workloads, delivering consistent memory bandwidth per core without exceeding the power budget of dense rack deployments.
In virtualized clusters and in-memory database platforms like SAP HANA, the Samsung M393A2K43BB1-CRC0Y 16GB DDR4-2400 RDIMM directly overcomes your most critical pain points with four essential features. ECC error correction silently fixes single-bit upsets from alpha particles or noise, preventing corrupted data that could crash a multi-VM host or distort financial records. The registered buffer redrives address and command signals, letting you populate all DIMM slots for high-capacity stability—vital when scaling to 384GB+ for large cache workloads. Its dual-rank x8 organization maximizes bank interleaving, boosting throughput in OLTP databases where every microsecond of latency impacts transaction rates. Operating at just 1.2V, this module cuts power draw and cooling overhead in always-on data centers, lowering your operational expenses and carbon footprint. For your mission-critical infrastructure, this memory provides unwavering data integrity, massive scalability, and energy-smart performance.
Server Memory Identified
This 16GB DDR4-2400 ECC Registered RDIMM (Dual Rank x8, CL17, 1.2V) is designed for server and workstation platforms requiring reliability and multi-channel memory architectures.
General Virtualization
Equip dual-socket servers with at least 8 identical modules (128GB total) evenly distributed across all memory channels. Populating one DIMM per channel (1DPC) in balanced configuration ensures optimal memory bandwidth for dozens of virtual machines while leaving slots free for future scaling. Stick to homogeneous 16GB RDIMMs to avoid NUMA penalties and maintain consistent ECC coverage.
In-Memory Database
Maximize capacity per server by fully populating all available DIMM slots. A 16-slot system with these 16GB modules delivers 256GB, suitable for medium-sized Redis or SAP HANA instances. Dual-rank x8 construction provides a good trade-off between density and signal integrity. If latency is critical, operate at the rated 2400MT/s and avoid mixing different ranks or capacities on the same channel.
High-Performance Computing
Achieve peak memory bandwidth by installing 8 or 12 modules per node in a balanced, symmetric channel population (e.g., one 16GB DIMM per channel across all available channels). The registered buffer and dual-rank design stabilize signal quality at scale, but confirm the CPU supports 2400MT/s at the target DIMM count. For bandwidth-sensitive workloads, this configuration effectively feeds many-core processors without introducing bottlenecks from unbalanced interleaving.
Rigorously tested server memory compatible with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR630.
Q: Can I mix this M393A2K43BB1-CRC0Y with other memory modules of different brands or speeds?
A: Mixing is not advised for Registered ECC memory. Different brands or speeds may cause instability. We recommend using identical modules with the same part number and speed to ensure reliable operation.
Q: Is this memory compatible with my system?
A: This DDR4-2400 RDIMM is designed for servers with Intel Xeon E5-2600 v3/v4 or Scalable platforms and select AMD EPYC systems. Always verify your motherboard's qualified vendor list for exact compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with the slot farthest from the CPU. For dual-socket servers, balance memory symmetrically across both processors to maximize interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, server-grade Registered ECC memory runs strictly at JEDEC standard DDR4-2400 with CL17 timings. Overclocking and XMP are not supported; stability and data integrity take priority.
Q: What warranty and typical failure rate can I expect?
A: This Samsung module includes a 1-year warranty. Enterprise RDIMMs undergo stringent testing, yielding a typical annualized failure rate well below 0.5%, making them ideal for 24/7 mission-critical environments.
