Samsung M393B2G70DB0-YK0 DDR3 Memory Modules Overview

The Samsung M393B2G70DB0-YK0 16GB DDR3 Registered Memory Module belongs to a specialized category of enterprise-grade server memory designed to support stability, scalability, and consistent performance in professional computing environments. This category focuses on ECC Registered DDR3 SDRAM RDIMM modules that are engineered for use in rack servers, tower servers, blade systems, and enterprise workstations where data integrity and predictable latency are essential. Unlike consumer desktop memory, this class of memory is purpose-built for sustained workloads, virtualization platforms, and mission-critical applications that demand continuous uptime.

DDR3 Registered memory modules in this category are designed to operate at a data transfer rate of 1600 megatransfers per second, classified as PC3-12800R, which allows them to deliver dependable bandwidth for legacy and transitional server architectures. These memory modules utilize advanced buffering technology that reduces electrical load on the memory controller, enabling systems to populate higher memory capacities without compromising signal integrity or system stability.

DDR3 SDRAM Technology in Registered DIMMs

This category is centered around DDR3 SDRAM technology, which represents a mature and proven memory standard widely adopted across enterprise systems for many years. DDR3 offers a balance of performance, power efficiency, and compatibility with a broad range of server platforms. Registered DDR3 DIMMs incorporate a register, also known as a buffer, between the DRAM modules and the memory controller, improving signal stability and allowing for higher memory density configurations.

DDR3 SDRAM operates at a lower voltage than earlier generations, contributing to reduced power consumption and heat output. For servers operating in dense racks or thermally constrained environments, this characteristic is particularly valuable. The category supports applications where predictable memory latency and stable throughput are more important than raw consumer-level speed benchmarks.

ECC Registered Architecture for Data Integrity

Error-Correcting Code, commonly referred to as ECC, is a defining feature of this memory category. ECC Registered DDR3 memory modules such as the Samsung M393B2G70DB0-YK0 are designed to detect and correct single-bit memory errors in real time. This capability significantly reduces the risk of data corruption, system crashes, and silent data errors that can compromise enterprise workloads.

In server environments where large datasets, databases, and virtual machines are constantly accessed and modified, ECC memory provides an essential layer of protection. The registered architecture further enhances stability by managing command and address signals, making this category suitable for systems that require maximum uptime and reliability.

Characteristics of PC3-12800R Memory Modules

Memory modules in the PC3-12800R category operate at an effective data rate of 1600 MT/s, delivering balanced bandwidth suitable for enterprise workloads. This performance level ensures compatibility with a wide range of Intel Xeon and AMD Opteron processors that support DDR3 registered memory. The CL11 latency rating provides predictable response times, which is crucial for applications that rely on consistent memory access patterns.

While newer memory technologies exist, the PC3-12800R category remains relevant for organizations maintaining legacy systems or extending the lifecycle of existing server infrastructure. These modules provide sufficient performance for virtualization, file servers, application servers, and network services without requiring a full platform upgrade.

Dual Rank x4 Memory Configuration

The Samsung M393B2G70DB0-YK0 features a dual rank x4 configuration, which is a key characteristic of this category. Dual rank modules contain two sets of memory ranks on a single DIMM, allowing the memory controller to interleave access and improve overall throughput. The x4 organization indicates that each DRAM chip processes four bits of data per cycle, enhancing error correction capabilities and compatibility with enterprise memory controllers.

This configuration is particularly beneficial in systems that require high reliability and compatibility with strict platform validation requirements. Dual rank x4 memory modules are commonly specified by server manufacturers for use in certified configurations, ensuring optimal performance and stability.

Latency and Timing Optimization

CL11 timing is a standard latency specification within this category, offering a balance between performance and stability. Server memory is optimized for consistency rather than aggressive overclocking, and CL11 timings ensure reliable operation under sustained workloads. This makes the category suitable for environments where memory errors or instability could lead to costly downtime.

Timing optimization in this category focuses on maintaining predictable performance across all memory channels, even when systems are fully populated. This approach supports enterprise scalability and simplifies capacity planning for IT administrators.

Compatibility with Enterprise Server Platforms

This memory category is designed for compatibility with a wide range of enterprise server platforms from leading manufacturers. Systems based on Intel Xeon E5 and E3 series processors, as well as select AMD server processors, commonly support DDR3 registered memory modules like the Samsung M393B2G70DB0-YK0. Compatibility extends to servers used in virtualization clusters, storage appliances, and application hosting environments.

Platform compatibility is a critical factor in enterprise memory selection, and this category emphasizes adherence to JEDEC standards and manufacturer specifications. This ensures seamless integration into certified server configurations without the need for custom tuning or firmware modifications.

Reliability and Longevity in Continuous Operation

Reliability is a defining characteristic of this memory category. Samsung DDR3 RDIMM modules are designed for continuous operation, often running 24 hours a day, seven days a week. This level of durability is achieved through high-quality components, robust PCB design, and extensive validation testing.

Long-term reliability reduces the total cost of ownership by minimizing the frequency of memory-related failures and replacements. This makes the category attractive for enterprises seeking dependable hardware solutions for long-term deployments.
