M393A8G40AB2-CVFBY 64GB PC4 DDR4 ECC Memory Overview

The Samsung M393A8G40AB2-CVFBY 64GB PC4-23400 DDR4-2933Mbps 2RX4 ECC Memory belongs to a specialized category of enterprise-grade server memory designed for mission-critical computing environments. This category focuses on registered ECC DDR4 DIMMs engineered to deliver high reliability, sustained bandwidth, and predictable latency under heavy workloads. Products in this category are developed to meet the strict requirements of data centers, cloud infrastructure providers, virtualization platforms, and enterprise IT deployments where stability and data integrity are paramount.

Unlike consumer-oriented desktop memory, this category prioritizes error correction, thermal consistency, long-term endurance, and platform compatibility with server-class CPUs and chipsets. The Samsung M393A8G40AB2-CVFBY exemplifies the defining attributes of this segment by combining high-density capacity, ECC protection, and JEDEC-standard DDR4-2933 performance to support modern server architectures.

High-Density 64GB DDR4 RDIMM

Memory modules within this category are built around high-density DRAM configurations to maximize capacity per slot, reducing the total number of modules required for large memory footprints. The 64GB capacity of the Samsung M393A8G40AB2-CVFBY enables scalable memory expansion in enterprise servers, allowing IT architects to design systems capable of handling large datasets, in-memory databases, and multi-tenant virtual environments.

The dual-rank by four configuration, identified as 2RX4, plays a critical role in balancing memory density and access efficiency. By distributing memory access across multiple ranks, this architecture enhances throughput while maintaining signal integrity. This design choice aligns with the broader category emphasis on predictable performance and compatibility with multi-channel memory controllers commonly found in server processors.

DDR4 and PC4-23400 Bandwidth Class

The PC4-23400 classification indicates a theoretical maximum bandwidth of approximately 23.4 GB/s per module, a defining feature of this category. DDR4-2933 memory operates at a data rate optimized for enterprise workloads that demand both speed and stability. This bandwidth level supports rapid data movement between CPU cores and memory, minimizing bottlenecks in applications such as analytics, virtualization, and transactional databases.

Within this category, adherence to JEDEC standards ensures cross-platform interoperability and long-term availability. The Samsung M393A8G40AB2-CVFBY is engineered to meet these specifications precisely, ensuring consistent performance across supported server platforms without the need for manual tuning or overclocking.

Registered DIMM Design for Signal Stability

The registered DIMM architecture found in this category includes a register or buffer between the DRAM modules and the memory controller. This design reduces electrical load on the memory controller, enabling support for higher memory capacities and more populated memory channels. The Samsung M393A8G40AB2-CVFBY leverages this architecture to maintain signal stability even in fully populated server configurations.

Registered memory is a cornerstone of enterprise server design, allowing system builders to scale memory without compromising reliability. This makes the category especially relevant for rack-mounted servers, blade systems, and high-density computing clusters.

Characteristics in Enterprise Workloads

Memory modules in this category are optimized for sustained performance rather than short bursts of speed. The DDR4-2933 data rate ensures that processors can access memory efficiently across a wide range of workloads. The Samsung M393A8G40AB2-CVFBY supports high core-count CPUs by delivering consistent throughput across multiple memory channels.

Enterprise workloads such as virtualization benefit significantly from high-capacity, high-bandwidth memory. Virtual machines often contend for memory resources, and the ability of this category to provide stable, high-density memory helps maintain predictable performance for each virtual instance.

Latency Optimization and Throughput Balance

While raw frequency is important, this category emphasizes a balanced approach to latency and throughput. DDR4-2933 memory modules are designed to operate within optimal timing parameters defined by JEDEC standards. The Samsung M393A8G40AB2-CVFBY achieves this balance by combining mature DDR4 technology with refined manufacturing processes.

This balance is crucial for applications that require both rapid access to small data sets and efficient streaming of large data blocks. Database servers, for example, rely on low-latency access for index lookups and high throughput for query processing.

Compatibility with Modern Server Platforms

The category encompassing the Samsung M393A8G40AB2-CVFBY is defined by broad compatibility with leading server processors and chipsets. DDR4-2933 ECC RDIMM memory is supported by numerous enterprise CPU families, making it a versatile choice for system integrators and IT departments.

Compatibility extends beyond processors to include server motherboards and firmware designed to recognize and manage registered ECC memory. This ensures seamless integration into existing infrastructures and simplifies upgrade paths for organizations expanding their memory capacity.

Scalability Across Multi-Socket Systems

Multi-socket servers present unique challenges in memory design, requiring modules that can maintain signal integrity across complex interconnects. The registered ECC memory category addresses these challenges by enabling high-density configurations across multiple CPU sockets. The Samsung M393A8G40AB2-CVFBY supports such scalability, making it suitable for enterprise servers with extensive memory requirements.

This scalability is particularly valuable in environments running large-scale virtualization platforms or in-memory analytics engines that demand uniform memory access across all processor sockets.

Reliability and Long-Term Operational Stability

Reliability is a defining characteristic of this memory category. Enterprise servers are expected to operate continuously, often for years, without interruption. The Samsung M393A8G40AB2-CVFBY is manufactured using rigorous quality control processes to ensure consistent performance and minimal failure rates.

Thermal stability is another key consideration. DDR4 memory in this category is designed to operate within specified temperature ranges while maintaining data integrity. This is essential in densely packed server racks where airflow and thermal management are critical factors.
