Overivew of Samsung M393A4K40BB1CRC 2400MT/s RDIMM ECC

The Samsung M393A4K40BB1CRC 32GB DDR4 2400MT/s PC4-19200 DDR4 SDRAM 288-Pin RDIMM Memory is part of a specialized enterprise memory category designed for high-performance server environments. This category focuses on DDR4 Registered DIMMs (RDIMM), engineered to provide a balance of speed, stability, and reliability for professional computing workloads. These memory modules are optimized for use in enterprise-grade servers, virtualization platforms, high-density data centers, mission-critical workloads, and compute-intensive applications that require continuous operation with consistent performance.

DDR4 2400MT/s Performance and Bandwidth

This memory category operates at 2400 megatransfers per second, delivering PC4-19200 bandwidth. The DDR4 2400MT/s speed tier is widely adopted in server platforms that require a balance between high throughput and operational stability. The Samsung M393A4K40BB1CRC ensures efficient communication between the memory controller and the DRAM modules, providing predictable performance under sustained workloads.

CAS Latency and Timing Stability

The Samsung M393A4K40BB1CRC features a CAS latency (CL) that is tuned for stability and predictability. While consumer memory may emphasize ultra-low latency for peak performance, this enterprise category prioritizes deterministic timing to ensure reliable operation across multiple workloads. Stable latency is critical for environments such as database servers, transactional systems, virtualized infrastructures, and cloud platforms, where consistent memory access directly affects application responsiveness.

Registered DIMM Architecture and System Stability

Registered DIMMs (RDIMMs) in this category include a register between the memory controller and the DRAM chips. This register buffers address and command signals, reducing the electrical load on the memory controller. The Samsung M393A4K40BB1CRC demonstrates the advantages of registered memory, including increased system stability, higher memory module density, and predictable performance in multi-DIMM configurations.

Electrical in High-Density Systems

Multi-socket and multi-channel server platforms place significant demands on the memory subsystem. Without buffering, unregistered memory can suffer from signal degradation and instability when multiple DIMMs are installed. The RDIMM architecture in this category mitigates these issues by isolating electrical signals and preserving signal integrity across all installed modules, reducing memory-related failures and improving overall system reliability.

Enterprise Server Platforms

Memory in this category is validated for compatibility with enterprise server motherboards and CPUs from major OEMs, including Dell, HPE, Lenovo, and Supermicro. The Samsung M393A4K40BB1CRC ensures predictable and certified operation in supported configurations, simplifying upgrades and expansions. RDIMM memory also supports advanced features such as multi-channel interleaving and higher memory population per channel, enhancing server performance and scalability.

Data Integrity and Enterprise Reliability

While the Samsung M393A4K40BB1CRC does not include ECC functionality, RDIMM memory in this category is often deployed alongside ECC-enabled memory controllers in enterprise server environments. ECC systems detect and correct single-bit errors, safeguarding sensitive workloads and improving system reliability. Even without ECC, the registered nature of these modules provides electrical stability, reduced signal interference, and predictable timing behavior, which collectively enhance reliability in mission-critical environments.

Ensuring Stability in Mission-Critical Applications

Enterprise workloads, including financial systems, scientific computing, healthcare IT, and virtualization clusters, demand high memory reliability. The RDIMM design in this category reduces the likelihood of memory-induced errors by maintaining consistent signal integrity across multiple channels. This contributes to the overall reliability of servers hosting critical applications and minimizes downtime due to memory faults.

32GB Module Density and Scalable Capacity

The 32GB module size in this category offers a balance between individual module capacity and system scalability. High-density memory modules allow for larger total memory configurations while occupying fewer DIMM slots. This is particularly important in servers with limited slot availability or in dense blade and rack-mounted systems, where efficient airflow and power management are critical.

Scalability and Cloud Infrastructure

Virtualized environments and cloud infrastructure deployments benefit from high-density memory modules, as they allow for larger memory allocations to virtual machines and higher consolidation ratios. IT administrators can deploy 32GB RDIMM modules incrementally, expanding server memory as workloads grow without replacing existing modules. This approach supports cost-effective scalability and efficient resource utilization.

Enterprise Deployment Strategies

This memory category supports diverse deployment strategies in enterprise IT. Database servers benefit from the high capacity to handle large datasets in memory, application servers can maintain consistent performance under peak load, and virtualization hosts can allocate sufficient memory to multiple virtual machines.
