The M393A2G40EB1-CRC3Q is a server-grade DDR4-2400 Registered DIMM with ECC, purpose-built for demanding enterprise platforms running virtualization, in-memory databases, and mission-critical workloads where data integrity is paramount. Its dual-rank x4 organization and registered signal type ensure stable operation at high memory densities, while CL17 latency and ECC correction deliver the reliability required for 24/7 operation.
1. With a generous 16GB capacity per module, it maximizes memory density per server node, enabling higher virtual machine consolidation without sacrificing performance.
2. Integrated ECC protection silently detects and corrects single-bit errors, preserving data integrity for mission-critical enterprise workloads.
3. The registered signal type buffers command and address lines, ensuring rock-solid signal integrity when populating all memory channels in large-scale server deployments.
4. Dual Rank x4 organization leverages rank interleaving to boost bandwidth efficiency, crucial for lowering latency in heavily threaded database operations.
5. Operating at 2400MT/s with DDR4 efficiency, it delivers ample throughput to keep pace with multi-core server processors, reducing I/O bottlenecks under peak loads.
The Samsung M393A2G40EB1-CRC3Q is a server-grade DDR4 RDIMM, purpose-built for environments where data integrity and relentless uptime define operational success. Its defining characteristics directly address the pain points of enterprise computing. The integrated ECC technology continuously detects and corrects single-bit memory errors, an essential shield against silent data corruption that could otherwise crash a densely packed virtualization cluster or silently poison financial transaction logs over a 24/7 lifecycle. This is not a luxury; it is the difference between confidence and catastrophic rebuilds. Complementing this, the registered signal buffer stabilizes high-capacity memory arrays by managing electrical loads on the CPU’s memory controller, allowing you to populate all channels with 16 GB modules like this one without sacrificing the speed needed for memory-hungry in-memory databases such as SAP HANA or large Redis deployments. The dual-rank x4 organization markedly improves bandwidth utilization by enabling interleaved access across internal banks, sustaining throughput when a database engine processes millions of concurrent queries. At 1.2V, it also trims thermal waste across a fleet of servers, lowering power bills without throttling performance. For the data center operator running virtual machine farms or real-time analytics, this module delivers a foundation of reliability, predictable low latency, and scalable efficiency where standard desktop memory would introduce unacceptable risk.
The M393A2G40EB1-CRC3Q is a 16GB DDR4-2400 registered ECC DIMM built for server deployments. Below are capacity planning recommendations for three common workload scenarios.
General Virtualization
Equip each memory channel with one 16GB RDIMM to balance bandwidth and capacity. On a dual-socket server with six channels per CPU, install 12 identical modules for 192 GB total. This symmetric population supports dense VM consolidation without creating memory bottlenecks.
In-Memory Database
Maximize capacity by filling every DIMM slot, even if the clock speed drops. Use two dual-rank modules per channel—24 pieces in a typical six-channel-per-socket platform—to reach 384 GB. Keeping the entire dataset in RAM delivers far greater value than preserving the peak 2400 MT/s frequency.
High Performance Computing
Install a single 16GB RDIMM per memory channel to sustain the full DDR4-2400 rate. A dual-CPU system populated with 12 modules (192 GB) provides balanced, high-bandwidth access. Maintain identical dual-rank x4 DIMMs across all channels to avoid clock-down penalties and ensure uniform latency.
Rigorously tested, this server RAM is validated for Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, etc.
Q: Can I mix this M393A2G40EB1-CRC3Q with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is discouraged for server RDIMMs. It may cause instability or POST failures. For guaranteed reliability, use identical modules with the same part number, rank, and configuration.
Q: Is this memory compatible with my system?
A: This DDR4-2400 RDIMM ECC module is compatible with servers supporting DDR4 Registered memory, including Intel Xeon E5-2600 v3/v4 or AMD EPYC platforms. Verify against your motherboard’s memory QVL for precise compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. Typically, populate identical modules per channel, starting with the slots farthest from the CPU. Balanced configurations ensure optimal performance, memory interleaving, and full bandwidth utilization.
Q: Does this module support overclocking or XMP profiles?
A: No. This server RDIMM adheres to JEDEC specifications. Overclocking and XMP profiles are not supported, as enterprise environments prioritize absolute stability and data integrity over variable speed enhancements.
Q: What warranty and typical failure rate can I expect?
A: It is covered by a 1-year warranty. The typical annualized failure rate is extremely low, reflecting rigorous enterprise-grade testing. You can expect highly reliable performance for demanding 24/7 server workloads.
