Engineer's Note

This DDR4-2400 Registered ECC DIMM is purpose-built for server and enterprise platforms, excelling in virtualization, in-memory databases, and data-integrity-critical workloads where dependable uptime is essential. Its dual-rank x8 organization maximizes memory bandwidth per channel, while the registered signal topology and ECC error correction deliver heightened signal integrity and protection against single-bit data corruption at the module’s native CL17 latency.

Technical Specs & Insights

1. ECC detection and correction eliminate silent data errors, preserving transactional consistency in enterprise database servers.
2. Registered buffering decouples the electrical load, allowing high-density memory populations without compromising signal quality in multi-socket platforms.
3. Dual Rank organization promotes bank-level parallelism, sustaining heavy virtual machine throughput under peak consolidation workloads.
4. Ample capacity per DIMM increases total memory headroom, enabling more virtualized workloads and larger in-memory caches per physical host.
5. Fast data transfer rate ensures responsive performance in latency-sensitive applications like real-time bid processing and OLAP queries.

Why These Specs Matter

Equipped with ECC, registered buffering, dual-rank organization, and 2400MHz speed, the Samsung M393A2K43CB1-CRC4Q 16GB DDR4 RDIMM directly solves server reliability and performance challenges. ECC correction eliminates silent data corruption—a single flipped bit can crash a virtualization host or corrupt financial transactions, but ECC protects every byte in real time. The registered buffer provides clean, amplified signals, enabling you to fully populate memory channels for massive in-memory databases without signal degradation. Its dual rank x8 architecture uses rank interleaving to overlap memory operations, increasing bandwidth: ideal when a hypervisor juggles dozens of VMs competing for low-latency access. Finally, the 2400MHz frequency with CL17 latency ensures responsive data delivery for caching and analytics workloads, while the 1.2V supply holds power consumption in check across dense server farms. The result is uncompromised data integrity, linear scalability, and the ability to consolidate more workloads safely.

Endurance & Reliability

This is a server-grade Registered DIMM (RDIMM) with ECC. Capacity planning recommendations for typical enterprise workloads:

General Virtualization
Install one 16GB RDIMM per memory channel to create a uniform configuration that sustains the full 2400MHz bandwidth. On an 8-channel platform, this gives 128GB of balanced capacity — ideal for hosting numerous virtual machines while avoiding interleaving penalties and maintaining low access latency.

In-Memory Database
Populate each channel with a single dual-rank DIMM to preserve CL17 timings and deliver 128GB at 2400MT/s for latency-sensitive in-memory datasets. If higher capacity is required, move to two DIMMs per channel; be prepared for a possible speed step-down to 2133MHz, and validate transactional performance under that condition.

High-Performance Computing
For HPC workloads demanding peak sustained bandwidth, use one DIMM per channel to obtain 19.2 GB/s per channel with minimal latency. Scale this 1‑DIMM‑per‑channel layout across all NUMA nodes, fully populating every channel to stream large scientific datasets without channel contention.

Verified Compatibility

Proven compatible after rigorous testing with servers like Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
