Highlights of Samsung M393A4K40BB1-CRC DDR4 2400MT/s Ram

The Samsung M393A4K40BB1-CRC 32GB DDR4 2400MT/s PC4-19200 DDR4 SDRAM CL17 288-Pin RDIMM ECC Registered Memory belongs to a specialized category of high-performance enterprise memory designed for stability, reliability, and scalability. This category focuses on DDR4 Registered DIMM (RDIMM) technology integrated with ECC (Error-Correcting Code), providing enterprise-grade data integrity and signal reliability. Memory modules in this category are engineered for professional computing workloads including high-density servers, virtualization platforms, mission-critical applications, cloud computing infrastructures, and data center deployments.

DDR4 2400MT/s Performance and PC4-19200 Bandwidth

This memory category operates at 2400 megatransfers per second, delivering a PC4-19200 theoretical bandwidth of 19.2 GB/s per module. Such performance ensures that server CPUs receive rapid access to memory resources, enabling efficient handling of high-volume workloads. The 2400MT/s speed tier is particularly suitable for enterprise servers where stable, sustained throughput is more critical than maximum peak performance.

CL17 Latency and Timing Consistency

The CAS latency (CL17) featured in this category is tuned for enterprise stability, balancing access speed with reliable operation. Unlike consumer memory modules that may focus on aggressive timing for peak performance, enterprise DDR4 RDIMM memory prioritizes deterministic latency to ensure predictable performance in high-density, multi-threaded environments. This timing stability is essential for servers running critical applications such as ERP systems, financial platforms, and cloud services.

RDIMM Architecture and Enterprise Reliability

Registered DIMMs include an internal register between the memory controller and DRAM chips, buffering address and command signals. This architectural feature reduces electrical loading on the memory controller, allowing servers to support more modules per channel and higher total memory capacity without compromising stability. The Samsung M393A4K40BB1-CRC RDIMM demonstrates how this design improves system reliability in high-density deployments.

Electrical Signal Integrity in Multi-DIMM Configurations

As server configurations increase in complexity with multiple DIMMs per channel, unbuffered memory can experience signal degradation, leading to instability and potential errors. RDIMM architecture in this category isolates and buffers electrical signals, maintaining signal integrity across all modules. This is especially critical in multi-socket servers, high-capacity virtualization hosts, and enterprise-grade blade or rack-mounted systems.

Platform Validation

Memory modules in this category undergo extensive OEM certification to ensure compatibility with a wide range of enterprise server platforms, including those from Dell, HPE, Lenovo, Supermicro, and other server vendors. The Samsung M393A4K40BB1-CRC RDIMM ECC is validated for predictable operation on certified platforms, reducing the risk of configuration errors and simplifying system expansion or upgrades. Registered memory modules support advanced platform features such as multi-channel interleaving, error correction, and higher DIMM population per channel.

ECC Functionality and Data Integrity

Error-Correcting Code (ECC) is a defining feature of this memory category, enabling the detection and correction of single-bit errors and the detection of multi-bit errors. ECC improves system stability, reduces the risk of data corruption, and enhances reliability in enterprise server environments. The Samsung M393A4K40BB1-CRC leverages ECC to protect mission-critical applications, including financial systems, scientific computing, healthcare databases, and large-scale virtualization deployments.

Mitigating Memory-Induced System Failures

Memory errors can arise from electrical noise, cosmic rays, voltage fluctuations, or hardware aging. Without ECC, these errors can lead to silent data corruption or system crashes. This category mitigates such risks through built-in error detection and correction mechanisms, ensuring that enterprise workloads maintain data integrity and reducing the frequency of unplanned downtime.

Enhanced Reliability for Continuous Operation

Servers in enterprise environments are often required to operate continuously, 24/7. ECC functionality in DDR4 RDIMM modules contributes to long-term operational reliability by providing hardware-level protection against transient memory faults.
