Overview of Samsung M393A4K40BB1-CRC0Q DDR4 PC4-19200

The Samsung M393A4K40BB1-CRC0Q 32GB DDR4 2400MT/s PC4-19200 SDRAM ECC Registered 288-Pin RDIMM Memory Module belongs to a specialized enterprise server memory category designed to support reliability-focused computing environments. This category encompasses registered DDR4 ECC memory modules engineered for professional servers, data centers, and mission-critical infrastructure where operational stability, data integrity, and predictable performance are non-negotiable requirements. Unlike consumer-grade memory, this category prioritizes validated compatibility, sustained throughput under load, and error mitigation mechanisms that operate continuously in the background.

Role of Registered DIMMs in Enterprise Memory Hierarchies

Registered DIMM architecture is a defining attribute of this memory category. By incorporating a register between the memory controller and DRAM chips, RDIMMs reduce electrical loading on the memory controller, enabling stable operation when multiple modules are installed per channel. This design allows servers to scale memory capacity far beyond what unbuffered DIMMs can support. The Samsung M393A4K40BB1-CRC0Q module aligns with this architectural requirement, ensuring signal integrity and timing accuracy across complex multi-channel configurations.

Memory Channel Load Reduction

The registered design offloads address and command signals, minimizing reflections and electrical noise. This optimization is critical in servers that operate with full memory banks populated. The category benefits include reduced error rates, improved stability, and enhanced compatibility with CPU-integrated memory controllers from leading server processor families.

DDR4 SDRAM Technology and Performance Foundations

DDR4 SDRAM represents a significant evolution in memory technology, and this category leverages its efficiency and scalability advantages. Operating at 2400MT/s, the Samsung M393A4K40BB1-CRC0Q module delivers PC4-19200 bandwidth, which remains a widely supported and highly stable speed grade across enterprise platforms. DDR4 reduces operating voltage compared to earlier generations, contributing to lower power consumption and improved thermal characteristics within server chassis.

Latency Behavior and Workload Consistency

Latency stability is a crucial factor in enterprise computing, and this category addresses it through conservative timing profiles validated for continuous operation. The Samsung M393A4K40BB1-CRC0Q module operates within JEDEC-defined parameters, ensuring that latency remains consistent even under heavy memory access patterns. This predictability benefits databases, middleware, and virtualization layers that rely on deterministic memory access behavior.

Bandwidth Distribution Across Multi-Core Processors

Modern server CPUs feature high core counts and multiple memory channels. This category supports balanced bandwidth distribution, allowing each core cluster to access memory efficiently. The result is improved overall system throughput and reduced contention during parallel processing tasks.

ECC Functionality and Data Protection

ECC technology is a cornerstone of this memory category, providing real-time detection and correction of single-bit memory errors. The Samsung M393A4K40BB1-CRC0Q integrates ECC at the hardware level, ensuring that transient errors caused by electrical interference or cosmic radiation do not compromise system stability or data accuracy. This capability is essential in enterprise environments where memory errors can propagate into serious application-level failures. This category is particularly valuable in long-running systems where memory remains active for extended periods without reboot cycles. ECC functionality continuously monitors memory integrity, maintaining system reliability across years of operation.

Impact of ECC on System Availability

By correcting errors transparently, ECC memory reduces the likelihood of unexpected crashes and data corruption. This directly contributes to higher system availability and reduced maintenance windows. For organizations operating under strict uptime requirements, this category provides a foundational layer of protection. Enterprise platforms often log corrected and uncorrected memory errors for proactive maintenance. This category supports such diagnostic capabilities, enabling administrators to identify degrading modules before they cause service disruption.

Physical Form Factor and Mechanical Design Standards

The 288-pin RDIMM form factor defines the physical characteristics of this memory category. Designed for server motherboards, this form factor ensures secure seating, precise electrical contact, and compatibility with standardized retention mechanisms. The Samsung M393A4K40BB1-CRC0Q adheres strictly to these physical specifications, enabling seamless installation and replacement. Mechanical durability is a key consideration within this category. Memory modules must withstand thermal cycling, airflow variations, and vibration within densely packed server racks.
