This is a DDR4-2133 Registered ECC DIMM purpose-built for servers and workstations, ideally deployed in virtualization hosts and in-memory database environments where data integrity and uptime are critical. Its registered signal architecture and dual-rank x8 organization deliver robust signal stability and efficient memory interleaving, while ECC and CL15 latency provide reliable error correction with responsive access for sustained enterprise workloads.
1. Registered buffer technology stabilizes command and address signals across fully populated memory channels, enabling dense server configurations to scale capacity without sacrificing operational reliability.
2. ECC protection continuously corrects single-bit errors in real time, shielding critical virtualization platforms and in-memory databases from silent data corruption.
3. Dual Rank x8 organization boosts interleaving efficiency, sustaining predictable memory bandwidth for numerous concurrent VMs during peak consolidation periods.
4. A capacity slice optimized for entry-level hyper-converged nodes supplies adequate headroom for essential services while keeping per-socket cost tightly contained.
5. Low 1.2V operation trims the thermal footprint per DIMM, cumulatively lowering cooling energy demand in multi-rack data center deployments.
Designed specifically for server and enterprise environments, the Samsung M393A1G43DB0-CPB0QS is an 8GB DDR4 RDIMM that transforms how your infrastructure handles mission-critical workloads. Its four core characteristics are not just specifications on paper; they are direct answers to the reliability and performance demands of data centers.
First, integrated ECC technology continually detects and corrects single-bit memory errors, silently protecting your virtualized clusters from data corruption and unexpected system crashes. In a memory-intensive database like SAP HANA, this means transactional integrity remains absolute, preventing costly downtime. Second, the registered signal buffer stabilizes the command and address buses, enabling you to populate all memory channels with multiple DIMMs without signal degradation. For a dense virtualization host running dozens of VMs, the RDIMM architecture guarantees boot-up certainty and sustained stability under heavy load. Third, the dual rank x8 organization leverages rank interleaving to boost bandwidth utilization. While one rank serves active data, the other precharges, effectively doubling throughput for real-time analytics and in-memory caching. Finally, operating at a low 1.2V, this DDR4-2133 module reduces thermal stress and energy consumption across your server farm, lowering cooling costs while delivering the consistent CL15 latency your applications depend on. This is not just memory; it is a foundation for uninterrupted, high-speed service delivery.
General Virtualization
Deploy one 8GB RDIMM per memory channel in dual-socket servers to maximize 2133MHz speed and channel interleaving. Populating eight slots per CPU yields 64GB per socket (128GB total), ideal for hosting 20–30 moderate VMs. ECC and register buffering deliver the stability essential for mixed workloads and live migration.
In-Memory Database
Prioritize total capacity by populating all DIMM slots, even if using two dual-rank modules per channel drops speed to 1866MHz. In a 2-socket platform with 16 slots each, 32 × 8GB modules provide 256GB, suitable for Redis or in-memory analytics. The Registered ECC design safeguards transactional data integrity at scale.
High-Performance Computing
For bandwidth-sensitive HPC, install one DIMM per channel across all available channels to sustain the full 2133MHz rate. A dual-CPU node with sixteen of these 8GB RDIMMs delivers 128GB at peak aggregate throughput, supporting simulation and modeling codes where per-core memory bandwidth is critical and latency is minimized.
Rigorously tested server memory; compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this M393A1G43DB0-CPB0QS with other memory modules of different brands or speeds?
A: Mixing this RDIMM with different brands or speeds is strongly discouraged. Mismatched modules can cause signal integrity issues, instability, or unbootable systems. For server environments, use identical part numbers and batches to ensure validated reliability and performance.
Q: Is this memory compatible with my system?
A: This DDR4-2133 Registered ECC module is designed for compatible server platforms, including Intel Xeon E5-2600 v4/Scalable and AMD EPYC 7000 series. Verify your server board supports 288-pin RDIMMs and check the qualified vendor list (QVL).
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate DIMMs per your server board's memory population guide, typically filling all channels symmetrically. Start with the farthest slot of each channel to balance load and maximize memory bandwidth. Always consult the system manual.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC module operating at JEDEC standard DDR4-2133, it does not support overclocking or XMP profiles. Its primary design goal is data integrity and 24/7 operational stability, not enthusiast tuning.
Q: What warranty and typical failure rate can I expect?
A: This module is backed by a one-year limited warranty. Enterprise-class ECC RDIMMs exhibit very low annualized failure rates, typically below 0.5%, ensuring high reliability for mission-critical workloads under specified operating conditions.
