DDR4 SDRAM Architecture and Key Characteristics

DDR4 SDRAM represents a significant evolution in memory technology, delivering improved bandwidth, lower operating voltage, and enhanced efficiency compared to previous DDR generations. The Samsung M391A1K43BB1-CRC operates at 2400MHz, classified as PC4-19200, enabling a theoretical bandwidth of up to 19.2GB per second. This performance profile supports smooth data flow between the processor and memory subsystem, reducing latency-related bottlenecks in compute-intensive tasks.

The DDR4 architecture introduces increased bank groups, improved prefetch mechanisms, and optimized signaling, all of which contribute to higher throughput and better responsiveness under load. In professional computing environments, these improvements translate into faster data processing, more responsive applications, and consistent system behavior during sustained workloads. This category is particularly valuable in environments where system uptime and predictable performance are essential.

2400MHz Operating Speed and PC4-19200 Bandwidth

The 2400MHz operating frequency places this memory module within a widely supported performance tier, ensuring compatibility with a broad range of chipsets and processors. PC4-19200 bandwidth enables efficient handling of transactional workloads, file services, and database operations where steady memory throughput is required. This speed grade is often preferred in enterprise and professional systems due to its balance of performance, stability, and thermal efficiency.

Systems equipped with 2400MHz DDR4 ECC UDIMM memory benefit from reduced wait times during memory access cycles. This helps processors maintain higher utilization rates, improving overall system efficiency. The consistent performance characteristics of this category also simplify system planning and scalability, as administrators can confidently deploy identical modules across multiple systems.

CAS Latency 17 and Memory Timing Optimization

CAS latency plays a crucial role in determining how quickly memory responds to read commands. With a CAS latency rating of 17, this module offers optimized timing that aligns well with its frequency rating. The result is a memory solution that delivers predictable responsiveness without sacrificing stability. In professional workloads, consistent timing behavior is often more valuable than marginal gains in raw speed.

Memory timing optimization in this category ensures compatibility with platform firmware and reduces the likelihood of timing-related instability. Samsung’s strict adherence to JEDEC standards further enhances reliability, allowing systems to operate within validated parameters across a wide range of environmental conditions.

Error-Correcting Code Technology for Data Integrity

ECC memory is a defining characteristic of this category, providing automatic detection and correction of single-bit memory errors. In environments where data accuracy is critical, such as financial systems, scientific computing, and enterprise services, ECC technology helps prevent data corruption, system crashes, and unpredictable behavior. The Samsung M391A1K43BB1-CRC integrates ECC functionality directly into its memory architecture, ensuring real-time error handling without performance penalties.

ECC UDIMM memory modules are particularly valuable in systems that operate continuously or handle sensitive data. By correcting memory errors before they impact applications or operating systems, this category enhances overall system resilience. ECC capability also contributes to longer system lifespan by reducing the cumulative effects of memory-related faults.

Single-Bit Error Correction and Multi-Bit Error Detection

The ECC mechanism employed in this memory category is capable of correcting single-bit errors and detecting multi-bit errors. This level of protection significantly improves system reliability, especially in environments exposed to electrical noise, temperature fluctuations, or long operational cycles. The ability to detect and report multi-bit errors also aids in proactive system maintenance and diagnostics.

For IT professionals and system integrators, ECC memory provides peace of mind by reducing the risk of silent data corruption. This is particularly important in applications where data accuracy directly affects outcomes, such as engineering simulations, accounting systems, and medical data processing.

Unbuffered UDIMM Design and Platform Compatibility

The unbuffered UDIMM design of the Samsung M391A1K43BB1-CRC ensures direct communication between the memory module and the memory controller. This architecture offers lower latency compared to registered memory while maintaining ECC functionality. As a result, this category is well suited for entry-level servers and professional desktops that support ECC UDIMM memory but do not require registered DIMMs.
