Built using Samsung’s advanced semiconductor manufacturing processes, this memory category delivers consistent performance under sustained workloads while maintaining electrical efficiency and signal integrity across densely populated memory channels.

DDR4 Technology and Performance Characteristics

DDR4 SDRAM technology forms the foundation of this category, offering significant improvements over DDR3 in terms of speed, power consumption, and signal integrity. Operating at a frequency of 2400MHz, equivalent to a data transfer rate of 2400MT/s, this memory category achieves a theoretical bandwidth of PC4-19200. This level of throughput supports high-performance computing tasks, data analytics workloads, and virtualization environments where multiple virtual machines operate concurrently.

Latency CL17 Timing

This category features memory modules with CAS latency CL17, striking a balance between latency and frequency that aligns well with enterprise workloads. While raw frequency determines bandwidth, latency plays a critical role in transactional applications, databases, and real-time processing tasks. CL17 timing ensures predictable response times and stable data access patterns, especially when combined with ECC and load-reduced buffering technologies.

Data Integrity Assurance

Error Correcting Code memory is a defining feature of this category, ensuring data accuracy in environments where even minor bit errors can lead to significant consequences. The ECC functionality embedded in the Samsung M386A4G40EM2-CRC memory module detects and corrects single-bit memory errors while identifying multi-bit errors. This capability is vital for enterprise servers that operate continuously and process sensitive or mission-critical data.

Reliability in Long-Term Server Operations

Server systems often run for months or years without interruption, making memory reliability a key consideration. The ECC architecture within this category works continuously in the background, correcting transient errors caused by electrical interference, cosmic radiation, or thermal fluctuations. This proactive error handling contributes to system stability and reduces maintenance interventions.

Load Reduced DIMM Technology and Scalability

Load Reduced DIMM technology is a core differentiator of the Samsung M386A4G40EM2-CRC memory category. LRDIMM modules incorporate a memory buffer that isolates the memory controller from the electrical load of the DRAM chips. This design significantly reduces signal loading, enabling servers to support higher memory capacities per channel compared to registered DIMMs.

Quad Rank Configuration Advantages

The quad rank design of this memory category further enhances capacity scalability. Each module contains four ranks of memory, enabling higher density within a single DIMM. This configuration is particularly beneficial in enterprise servers that require large memory pools for in-memory databases, virtualization clusters, and high-performance computing applications.

Memory Population Flexibility

Servers equipped with LRDIMM memory modules can achieve flexible memory population strategies, enabling administrators to balance capacity, performance, and cost. This category supports configurations that maximize memory per CPU socket, which is essential for workloads that benefit from large contiguous memory spaces. By selecting load reduced, quad rank modules, organizations can design systems that accommodate future expansion without requiring immediate hardware replacement. This forward-looking scalability makes this memory category suitable for growing enterprises and evolving workloads.
