This 32 GB DDR4-2400 registered ECC RDIMM is purpose-built for server platforms and memory-intensive enterprise workloads such as virtualization, in-memory databases, and dense compute clusters where data integrity is non-negotiable. Its dual-rank x4 organization drives superior interleaving efficiency for increased throughput, while the registered signal buffering, ECC error correction, and tight CL17 latency collectively ensure rock‑solid signal stability and reliable 24/7 operation in multi‑DIMM configurations.
1. ECC protection actively detects and corrects single-bit errors in real time, preserving data integrity for mission-critical databases and financial transaction processing.
2. Registered signal buffering decouples the command bus from module loading, enabling stable operation across densely populated servers without jeopardizing control signal quality.
3. Dual Rank x4 organization saturates the memory channel with efficient interleaving, boosting throughput for heavily consolidated virtual machines and containerized microservices.
4. A 32GB capacity per stick increases the overall memory footprint per server node, allowing larger in-memory datasets and smoother scale-up for business analytics platforms.
5. The PC4-19200 bandwidth standard provides a balanced ceiling of concurrent data movement, ensuring consistent performance for always-on cloud hosting and enterprise application pools.
The Samsung M393A4K40BB1-CRC4Y is a server-grade 32GB DDR4 RDIMM engineered for mission-critical enterprise workloads, where unplanned downtime is measured in lost revenue per minute. In a dense virtualization cluster hosting dozens of VMs, its ECC technology actively detects and corrects single-bit memory errors caused by cosmic radiation or electrical noise. This is not theoretical safeguard; it directly prevents silent data corruption that could crash hypervisors or quietly poison transaction records inside a virtualized database. The registered signal architecture buffers command and address lines, keeping electrical loading low so you can populate all 24 DIMM slots per 2U node without sacrificing 2400MHz stability — essential when scaling a VMware farm or an in-memory database like SAP HANA that demands terabyte-scale footprints. Its dual-rank x4 organization interleaves two independent ranks of DRAM on a single module, delivering measurably higher sustained bandwidth under concurrent access patterns. For a financial trading system running Redis or Memcached, that translates to lower latency and higher throughput during market spikes. The 1.2V operating voltage reduces thermal load across the entire rack, buying you headroom in power-constrained data centers while keeping cooling costs predictable as you scale. Every one of those 288 pins is a commitment to signal integrity, ensuring that when a node is servicing thousands of simultaneous in-memory queries, the memory bus does not become the bottleneck.
General Virtualization
For a balanced virtualization host running multiple VMs, populate all memory channels symmetrically to maximize bandwidth. We recommend starting with four or six identical 32 GB RDIMMs (128–192 GB total) to handle moderate consolidation ratios while leaving slots free for growth.
In-Memory Database
In-memory databases demand both capacity and reliability. Deploy a fully populated configuration using 16 or more of these 32 GB dual-rank RDIMMs to reach 512 GB or 1 TB, exploiting interleaving across all channels for lowest latency under heavy OLTP workloads.
High-Performance Computing (HPC)
HPC clusters benefit from high bandwidth and ECC protection. Install one DIMM per channel (e.g., 8 x 32 GB = 256 GB) on a dual-socket node to achieve the memory throughput required for simulation and modeling codes, keeping ranks balanced to avoid channel bottlenecks.
Validated for server use, rigorously tested; compatible with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this M393A4K40BB1-CRC4Y with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not advised. It can cause instability and forces all modules to operate at the lowest common speed, compromising server reliability and performance.
Q: Is this memory compatible with my system?
A: This DDR4-2400 ECC Registered DIMM is designed for server platforms like Intel Xeon E5-2600 v3/v4 or AMD EPYC 7001. Always consult your motherboard's qualified vendor list for confirmed compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs in each channel following your server manual. Typically, install one DIMM per channel first for balanced memory interleaving, then fill remaining slots symmetrically to maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC module, it adheres strictly to JEDEC DDR4-2400 standards. Overclocking and XMP are unsupported to maintain absolute data integrity and operational stability.
Q: What warranty and typical failure rate can I expect?
A: This Samsung module includes a 1-year warranty. It demonstrates an exceptionally low annualized failure rate, typically around 0.1–0.3%, owing to rigorous enterprise-grade testing and quality assurance processes.
