This DDR4-2933 registered ECC RDIMM leverages its single-rank x8 configuration and hardware error correction to deliver superior signal integrity and data reliability, making it ideal for memory-intensive server workloads such as virtualization and in-memory databases. Its registered signal type ensures stable operation under high-density memory configurations, guaranteeing consistent performance in enterprise platforms where uptime and accuracy are critical.
1. ECC detection and correction eliminates silent data corruption, ensuring uninterrupted accuracy for financial transactions and database operations in always-on server environments.
2. Registered signal buffering stabilizes large memory populations, allowing fully loaded server boards to support heavy virtualization without compromising data integrity.
3. RDIMM form factor guarantees compatibility with enterprise server platforms, delivering the predictable reliability demanded by data center provisioning standards.
4. The generous memory bandwidth accelerates parallel data throughput, reducing latency spikes across co-hosted containers and microservices in cloud-native infrastructures.
5. Single Rank organization lowers electrical loading per channel, preserving signal cleanliness and enabling consistent access timings in high-density rack deployments.
Designed for mission-critical server environments, the Samsung M393A1K43DB1-CVFBY RDIMM transforms raw specifications into tangible operational resilience. As a DDR4-2933 Registered DIMM with ECC, this 8GB single-rank x8 module directly addresses the challenges faced in virtualized clusters and in-memory databases. When running a dozen virtual machines on a single hypervisor, memory errors from cosmic background radiation can silently corrupt data; the integrated ECC engine automatically detects and corrects single-bit flips, preventing costly VM crashes and ensuring continuous service availability. For latency-sensitive applications like Redis or SAP HANA, the Registered signal buffer stabilizes the electrical load across multiple DIMMs, allowing dense configurations without sacrificing the 2933 MT/s bandwidth—critical when sub-millisecond query responses determine user experience or real-time financial analysis. Moreover, the single-rank architecture at 2933MHz delivers optimal interleaving efficiency and lower power draw at 1.2V, reducing total cost of ownership in scale-out server farms. This isn’t just memory; it’s the foundation for data integrity and uninterrupted performance in enterprise workloads where reliability isn’t negotiable.
This 8GB DDR4-2933 ECC Registered DIMM (RDIMM) is built for servers where reliability and balanced throughput are critical. The following capacity planning recommendations target typical data-center workloads.
General Virtualization
Populate all memory channels uniformly with these 8GB RDIMMs to balance capacity and bandwidth. For a dual-socket server with eight channels per CPU, install one DIMM per channel (16 modules, 128 GB) to support numerous VMs without contention. Leave remaining slots for future scaling.
In-Memory Database
Maximize capacity while maintaining one DIMM per channel (1DPC) to sustain the full 2933MHz speed; this yields 128 GB across 16 slots on a typical dual-processor platform. Keeping data close to the CPU at the lowest latency is critical for real-time analytics. If datasets exceed 128 GB, carefully evaluate 2DPC configurations that may downclock to 2666 MHz.
High-Performance Computing (HPC)
Fill every memory channel with a single 8GB RDIMM to achieve maximum 2933MHz bandwidth and minimal latency. An 8-channel platform provides 64 GB, ideal for bandwidth-bound simulations. When greater capacity is needed, scale by adding identical DIMMs across all channels to maintain interleaving and avoid frequency penalties.
Rigorously tested server memory. Works with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this M393A1K43DB1-CVFBY with other memory modules of different brands or speeds?
A: Mixing registered server memory with different brands or speeds is risky. It may cause POST failures or instability. For reliable operation, use identical modules with the same part number, rank, and frequency across all channels.
Q: Is this memory compatible with my system?
A: This Samsung RDIMM suits Intel Xeon Scalable or AMD EPYC platforms with DDR4-2933 support. Verify your server board’s qualified vendor list and ensure it accepts 288-pin Registered ECC DIMMs; consumer desktops are incompatible.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board’s manual, typically populating identical DIMMs per channel, starting with the farthest slot from the CPU. Balance capacity across memory channels and avoid mixing single-rank and dual-rank configurations for best throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise RDIMM using JEDEC standard DDR4-2933 at CL21. It does not support XMP, overclocking, or voltage adjustments. It is designed for stability under 24/7 mission-critical workloads, not for enthusiast tuning.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. Server-grade Samsung RDIMMs exhibit very low annualized failure rates, typically under 0.5% in properly cooled environments, ensuring long-term reliability for enterprise deployments.
