Samsung M393A2K43BB1-CRC 16GB DDR4 Memory

The Samsung M393A2K43BB1-CRC 16GB PC4-19200 DDR4-2400MHz Dual Rank x8 CL17 ECC Registered SDRAM represents a specialized class of enterprise-grade server memory engineered for sustained reliability, predictable performance, and compatibility with modern server platforms. This category of RDIMM server memory is designed to operate within demanding data center and enterprise environments where uptime, data integrity, and workload consistency are essential. The PC4-19200 rating corresponds to a theoretical peak bandwidth of 19.2 GB/s per module, ensuring sufficient throughput for multi-core processors handling virtualization, database operations, analytics workloads, and enterprise applications. In this category, Samsung’s engineering emphasis is placed on long-term stability, platform validation, and strict adherence to JEDEC standards, ensuring predictable behavior across certified server motherboards.

Registered DIMM

Registered DIMMs, commonly referred to as RDIMMs, introduce a register between the memory controller and the DRAM modules to buffer command and address signals. This architectural choice significantly improves signal integrity, especially when deploying large memory capacities across multiple DIMM slots per channel. The Samsung M393A2K43BB1-CRC exemplifies this RDIMM category by enabling servers to support higher total memory capacities without sacrificing stability or timing reliability. RDIMMs mitigate this challenge by reducing the electrical load seen by the memory controller, allowing for consistent operation at rated speeds even when all memory channels are fully populated. This design approach is particularly relevant in dual-socket and multi-socket servers where memory scalability directly influences workload consolidation and performance density.

Data Integrity

Error Correcting Code functionality is a defining characteristic of this server memory category. ECC memory modules like the Samsung M393A2K43BB1-CRC include additional memory chips dedicated to detecting and correcting single-bit errors and detecting multi-bit errors during data transactions. This capability is vital in environments where data corruption, even at a minimal level, can lead to system crashes, application failures, or silent data corruption. ECC Registered DDR4 memory is extensively used in mission-critical systems such as enterprise databases, virtualization hosts, financial systems, and scientific computing platforms. The inclusion of ECC support ensures that transient electrical interference, cosmic radiation, or component aging does not compromise data accuracy. Over extended operational periods, this protection contributes to overall system reliability and reduced maintenance overhead.

Dual Rank x8

The dual rank x8 configuration of the Samsung M393A2K43BB1-CRC plays a significant role in balancing performance and compatibility. Dual rank memory modules effectively present themselves as two logical memory banks to the memory controller, enabling improved memory interleaving and potentially higher throughput in supported server architectures. This configuration is widely compatible with mainstream server CPUs from major vendors, ensuring optimal channel utilization. The x8 chip organization refers to the width of each DRAM chip’s data interface, which aligns with ECC requirements and server chipset expectations. This configuration provides an optimal balance between reliability, performance, and cost efficiency, making it a standard choice in enterprise RDIMM categories.

Performance

The DDR4-2400 speed grade defines an effective data transfer rate of 2400 MT/s, positioning this memory category within a widely supported performance tier for enterprise servers. DDR4-2400 remains a common baseline speed across many Intel Xeon and AMD EPYC platforms, offering dependable throughput without introducing compatibility constraints that may arise with higher frequency modules. Latency characteristics, such as CAS Latency 17, are tuned to provide consistent access times that align with server workload patterns. While raw frequency contributes to bandwidth, balanced latency ensures predictable performance across transactional and multi-threaded applications. This category of memory emphasizes sustained throughput and stability over aggressive overclocking or consumer-focused performance metrics.

Bandwidth

Modern server processors rely on multi-channel memory architectures to maximize bandwidth availability. The Samsung M393A2K43BB1-CRC fits seamlessly into these architectures, allowing multiple RDIMMs to operate in parallel across channels. When deployed correctly, this configuration ensures that memory-intensive workloads such as virtualization, in-memory databases, and large-scale analytics can operate without bottlenecks. Balanced memory population across channels is a key consideration in server design, and this category of memory supports standardized population rules defined by server OEMs. By adhering to JEDEC specifications, the module ensures predictable behavior when mixed with identical or equivalent RDIMMs, facilitating scalable system configurations.

Thermal

Enterprise server memory must operate continuously under varying thermal conditions, often within densely packed chassis. DDR4 RDIMMs such as the Samsung M393A2K43BB1-CRC are designed to maintain signal stability and data integrity across specified temperature ranges. Lower operating voltage contributes to reduced heat generation, which in turn supports higher memory density without compromising system cooling efficiency. Power efficiency is not only a cost consideration but also a reliability factor.

Compatibility

This category of Samsung server memory is validated for compatibility with a wide range of enterprise server platforms. RDIMM ECC DDR4-2400 modules are commonly supported by Intel Xeon Scalable processors, earlier Xeon E5 and E7 families, and corresponding server-grade chipsets. Compatibility extends to numerous server motherboards from major OEMs that adhere to JEDEC DDR4 RDIMM standards. Platform validation is a critical differentiator in enterprise memory categories. Samsung’s extensive qualification process ensures that modules like the M393A2K43BB1-CRC meet stringent electrical, thermal, and timing requirements across supported platforms.

Scalability

Scalability is a defining requirement for data center memory solutions. The Samsung M393A2K43BB1-CRC fits within a category designed for incremental expansion, allowing organizations to start with modest memory configurations and scale upward as workload demands increase. RDIMM architecture supports higher total memory capacities per system compared to unbuffered DIMMs, making it suitable for growth-oriented infrastructure planning. Consistent module specifications across this category simplify capacity planning and lifecycle management. IT teams can deploy identical memory modules across multiple servers, ensuring uniform performance characteristics and easing maintenance and replacement processes.

Form Factor

The 288-pin RDIMM form factor defines the physical layout of this memory category. This design accommodates the additional register chip and ECC components required for server-grade functionality. Heat dissipation characteristics are optimized through PCB design and component placement. While typically deployed without large heat spreaders, these modules rely on server airflow patterns to maintain operating temperatures within specification, aligning with standard data center cooling strategies.

Use Cases

This category of Samsung DDR4 ECC Registered server memory is deployed across a wide range of professional environments. Enterprise databases benefit from ECC protection and predictable latency, ensuring transaction integrity and minimizing downtime. Application servers rely on stable memory performance to support concurrent user access and background processing tasks. Virtualization hosts represent a primary use case, where memory density and reliability directly impact consolidation efficiency. RDIMM modules enable higher total memory capacities, supporting more virtual machines per host without compromising stability.
