370-BCCZ Dell 64GB 6400mhz Pc5-51200 Dual Rank Ddr5 Memory.

Dell 370-BCCZ 64GB Memory Module

Enterprise-grade DDR5 memory represents a significant leap forward in server technology, delivering unprecedented performance, reliability, and efficiency for demanding data center environments. The transition from DDR4 to DDR5 architecture brings substantial improvements in bandwidth, power management, and error correction capabilities that are essential for today's computational workloads.

Understanding DDR5 Server RDIMM Architecture

DDR5 server memory introduces a revolutionary approach to memory subsystem design with its dual 32-bit/40-bit sub-channels (for non-ECC/ECC respectively) per module. This architectural enhancement significantly improves memory access efficiency and reduces latency compared to the single 64-bit/72-bit channel architecture of DDR4. The Dell 370-BCCZ leverages this advanced architecture to deliver optimal performance in multi-processor server environments.

Key DDR5 Architectural Advancements

The DDR5 standard incorporates several critical innovations including on-die ECC for internal error correction, a redesigned command/address bus with double the bank groups, and decision feedback equalization (DFE) for improved signal integrity at higher speeds. These advancements work in concert to provide the reliability and performance demanded by enterprise applications and cloud computing infrastructure.

Key Specifications

The Dell 370-BCCZ 64GB DDR5 server memory module represents the pinnacle of memory technology, engineered specifically for high-performance server applications requiring exceptional reliability and bandwidth. This module incorporates the latest DDR5 advancements to deliver optimal performance in Dell PowerEdge servers and compatible systems.

Core Memory Specifications

Form Factor and Physical Dimensions

The module utilizes the standard 288-pin RDIMM form factor, ensuring compatibility with Dell PowerEdge servers and other compatible systems designed for DDR5 server memory. The physical dimensions adhere to JEDEC specifications, with careful attention to component placement and thermal considerations for optimal operation in constrained server environments.

ECC and Registered Technology

Error Correcting Code (ECC) and Registered memory technologies represent critical differentiators between server-grade and consumer memory modules. The Dell 370-BCCZ incorporates both technologies to ensure maximum data integrity and system stability in mission-critical environments.

Error Correcting Code (ECC) Implementation

The ECC functionality in this DDR5 module provides single-bit error correction and multi-bit error detection capabilities. This advanced error correction goes beyond the on-die ECC present in all DDR5 memory by providing chip-level error correction across the entire module. This comprehensive approach to data integrity is essential for applications where data corruption is unacceptable.

ECC Operational Details

The ECC implementation utilizes additional memory chips to store error correction codes alongside the primary data. When data is read from memory, the ECC logic verifies the integrity of the data and automatically corrects single-bit errors without impacting performance. Multi-bit errors are detected and reported to the system management controller for appropriate handling.

Registered Memory Architecture

The Registered (RDIMM) design incorporates register chips between the memory controller and the DRAM chips. These registers buffer the command and address signals, reducing the electrical load on the memory controller and enabling support for higher memory capacities per channel. This architecture is essential for maintaining signal integrity in systems with large memory configurations.

Benefits of Registered Design

Registered memory provides several critical advantages for server environments, including improved signal integrity at high speeds, support for higher memory densities, and reduced electrical load on the memory controller. These benefits translate to enhanced system stability and reliability, particularly in multi-processor systems with extensive memory configurations.

Performance Characteristics and Bandwidth Analysis

The performance capabilities of the Dell 370-BCCZ DDR5 memory module represent a substantial advancement over previous generation memory technologies. Understanding these performance characteristics is essential for proper system configuration and workload optimization.

Bandwidth and Transfer Rates

Operating at 6400MT/s, this module delivers a theoretical peak bandwidth of 51.2 GB/s. The actual achievable bandwidth depends on several factors including processor architecture, memory configuration, and workload characteristics. The PC5-51200 designation confirms compliance with JEDEC specifications for this performance level.

Real-World Performance Considerations

While theoretical bandwidth provides a useful benchmark, real-world performance is influenced by multiple factors including memory timings, inter-socket communication efficiency, and application memory access patterns. The dual-rank design of this module often provides better performance than single-rank modules in server workloads due to improved bank interleaving opportunities.

Latency Characteristics

The CL52 CAS latency specification must be understood in the context of the higher operating frequency of DDR5 memory. While the absolute latency in nanoseconds is comparable to high-performance DDR4 memory, the significantly increased bandwidth provides substantial performance benefits for most server workloads, particularly those with high memory bandwidth requirements.

Timing Parameters and Optimization

Beyond the primary CAS latency, numerous secondary and tertiary timing parameters contribute to overall memory performance. The Dell 370-BCCZ is optimized with timing parameters that balance performance and reliability for enterprise workloads. These timings are carefully validated during the manufacturing and qualification process to ensure compatibility and stability.

Supported Server Platforms

This memory module is validated for use in Dell PowerEdge servers that support DDR5 technology, including latest generation platforms with Intel Xeon Scalable processors and compatible architectures. Specific compatibility should be verified through Dell's official compatibility matrices and system documentation.

Optimized Application Workloads and Use Cases

The performance characteristics of the Dell 370-BCCZ make it particularly well-suited for specific server workloads and applications. Understanding these optimal use cases helps in selecting the appropriate memory configuration for your specific requirements.

Virtualization and Cloud Infrastructure

High-density virtualization environments benefit significantly from the large capacity and bandwidth provided by these modules. The 64GB capacity allows for substantial virtual machine density per server, while the high bandwidth supports memory-intensive virtualized applications and high consolidation ratios.

Database and Transaction Processing

Database management systems, both relational and NoSQL, derive substantial performance benefits from the combination of high capacity and bandwidth. In-memory databases and large buffer pool configurations particularly benefit from the capabilities of these high-performance modules.

High-Performance Computing and Analytics

Scientific computing, financial analytics, and big data processing workloads often exhibit memory bandwidth limitations. The 6400MT/s operation speed of these modules helps alleviate these bottlenecks, improving overall application performance and reducing time to results.

PMIC Functional Benefits

The PMIC enables more efficient power delivery by placing voltage regulation closer to the DRAM devices. This distributed power architecture reduces power loss and noise while providing better voltage regulation across the module. The PMIC also supports advanced power states and more granular power management.
