Designed specifically for enterprise server platforms, this Samsung 32GB DDR4-2400 RDIMM (M386A4K40BB0-CRC) leverages ECC and registered signal technology to guarantee data integrity and signal stability in high-density deployments, making it ideal for virtualization, in-memory databases, and mission-critical workloads. Its dual-rank x4 organization enhances memory bandwidth utilization and enables higher capacity configurations per channel, while the CL17 latency provides a balanced response profile for sustained throughput under heavy multi-threaded access patterns.
1. 32GB capacity per module supplies the headroom needed to pack more virtual machines and containers onto a single server, reducing memory contention in software-defined data centers.
2. ECC protection silently corrects single-bit errors and detects multi-bit faults, preserving data integrity for transactional databases and financial processing around the clock.
3. Registered signal buffering stabilizes command and address lines when fully populating multi-slot server boards, enabling seamless scaling to hundreds of gigabytes in dense rack deployments.
4. Dual Rank x4 organization interleaves memory accesses to keep server-class memory channels saturated, delivering predictable throughput during simultaneous analytics queries and backup jobs.
5. 2400MT/s transfer rate provides cost-efficient bandwidth for mainstream enterprise workloads, balancing performance with the thermal constraints of high-density server farms.
Engineered for relentless data center workloads, the Samsung M386A4K40BB0-CRC, a 32GB DDR4-2400 RDIMM, translates four key attributes into operational advantages. ECC proactively corrects single-bit errors caused by cosmic radiation; without it, a random bit flip in a virtualized cluster could silently corrupt critical databases or crash dozens of guest machines, jeopardizing business continuity. The Registered buffer stabilizes command and address signals, letting you fully populate memory channels for massive in-memory databases like SAP HANA without stability risks. Dual Rank x4 organization employs bank interleaving to boost bandwidth, accelerating parallel data requests for real-time analytics. Its 32GB capacity per stick maximizes density, lowering total cost of ownership by leaving room for future growth and minimizing DIMM slots used. This delivers hardened data integrity, stable high-capacity configurations, and the performance headroom your mission-critical virtualized environments and database servers require.
General Virtualization
For consolidated virtualization hosts, populate all available memory channels symmetrically to maximize bandwidth and reduce contention. Using six or eight of these 32 GB RDIMMs per socket (192–256 GB total) delivers a balanced foundation for dozens of mixed-role VMs without oversubscribing host memory.
In-Memory Database
In-memory databases demand both high capacity and strong data integrity. Deploy these ECC Registered DIMMs in a fully balanced configuration—typically 12 or 16 modules across two sockets—to reach 384–512 GB, keeping the in-memory working set entirely in RAM. The dual-rank x4 organization provides the reliability and refresh management essential for persistent memory-resident workloads.
High-Performance Computing (HPC)
HPC nodes require peak memory bandwidth per core. Install one DIMM per channel across all memory channels (commonly 8 modules per socket for 256 GB) to eliminate bandwidth bottlenecks for simulation and modelling codes. The 2400 MT/s registered interface and dual-rank design help sustain consistent throughput under heavy floating-point and vector workloads.
Rigorously tested server memory, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and similar systems.
Q: Can I mix this M386A4K40BB0-CRC with other memory modules of different brands or speeds?
A: Mixing modules is strongly discouraged in server environments. Even identical specs from different brands can cause instability. For reliable ECC and registered operation, use identical Samsung modules with matching rank, speed, and CAS latency.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-2400 RDIMM is compatible with Intel Xeon E5-2600 v4/v3 and AMD EPYC 7001 series platforms. Verify your server board supports registered ECC memory and 288-pin DDR4 slots before ordering.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-socket servers, populate identical DIMMs in matching slots per CPU, one per channel first. Follow your motherboard’s memory population guide; typically, fill blue slots before black to maintain balanced memory interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This registered ECC RDIMM runs at fixed JEDEC timings (DDR4-2400, CL17) and does not support overclocking or XMP. Server memory prioritizes data integrity and stability over speed adjustments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise DDR4 RDIMMs exhibit very low annualized failure rates (typically <0.2%) under proper thermal conditions, ensuring high reliability for mission-critical workloads.
