Dell 370-BBRX 64GB DDR5 Server Memory Module

Capacity

The Dell 370-BBRX memory module features a substantial 64GB capacity configured as a single 1x64GB module. This high-density memory configuration is engineered for servers requiring significant memory resources while maintaining flexibility in slot utilization. The single-module design allows for efficient memory expansion without immediate need for complete bank population, providing cost-effective scalability for growing enterprise environments.

Memory Technology and Performance

Utilizing cutting-edge DDR5 SDRAM technology, this module operates at a swift 5600MT/s data rate, significantly outperforming previous DDR4 generations. The PC5-44800 classification indicates the module's peak transfer rate of 44800 MB/s, enabling accelerated data processing for memory-intensive applications. This enhanced bandwidth is crucial for modern server workloads including virtualization, database management, and high-performance computing tasks.

Advanced Memory Architecture

ECC Registered Technology

The Dell 370-BBRX incorporates Error Correcting Code (ECC) technology with registered buffering, providing enterprise-grade reliability for critical server operations. ECC functionality automatically detects and corrects single-bit memory errors while identifying multi-bit errors, significantly reducing system crashes and data corruption. The registered design includes buffer chips that reduce electrical load on the memory controller, enabling support for higher memory capacities and improved signal integrity across densely populated memory channels.

2Rx4 Rank and Bank Organization

This module features a 2-rank by 4-bit organization (2Rx4), indicating two independent memory ranks each accessing data through a 4-bit wide interface. This architecture optimizes memory controller efficiency by allowing alternating access between ranks, effectively hiding precharge and activation delays. The 2Rx4 configuration provides balanced performance characteristics ideal for server environments requiring consistent, low-latency memory access across sustained operational periods.

Dell PowerEdge Server Compatibility

The 370-BBRX memory module is specifically engineered for compatibility with Dell PowerEdge server systems, including recent generations supporting DDR5 technology. This module is validated for use in PowerEdge platforms requiring 5600MT/s memory speeds, ensuring optimal performance and reliability when deployed in approved configurations. The memory undergoes rigorous testing within Dell's qualification process to guarantee seamless integration with PowerEdge hardware and management systems.

288-Pin RDIMM Form Factor

The module utilizes the standard 288-pin Registered DIMM (RDIMM) form factor with a specific notch keying pattern that prevents installation in incompatible systems. The physical dimensions conform to JEDEC standards for server memory modules, ensuring proper fit within PowerEdge memory slots. The 288-pin interface provides the necessary signal lines for data transfer, addressing, command functions, and advanced features specific to DDR5 registered memory architecture.

Voltage and Power Management

Operating at a nominal 1.1 volts, this DDR5 module represents a significant power efficiency improvement over previous generations. The reduced voltage requirement decreases overall power consumption and heat generation within the server environment. Integrated power management circuitry provides fine-grained control over power delivery, enabling advanced energy-saving modes without compromising performance during active operation. This efficiency is particularly valuable in densely configured servers where thermal management and power budgeting are critical concerns.

Performance Characteristics and Benefits

The module operates at CAS Latency 46 (CL46), which defines the number of clock cycles between a read command and data availability. While the absolute latency appears higher than previous generations, the significantly increased clock speed of DDR5 technology results in substantially improved actual access times. The complete timing parameters are optimized for server workloads that benefit from high bandwidth and sustained transfer efficiency rather than ultra-low latency alone.

Bandwidth and Data Transfer Efficiency

With a theoretical peak bandwidth of 44.8 GB/s per module, the 370-BBRX delivers substantial data transfer capabilities essential for modern server applications. The DDR5 architecture improves efficiency through enhanced burst capabilities, better bank grouping, and improved command rate optimization. These features collectively reduce bottlenecks in memory-intensive operations, allowing processors to maintain higher utilization rates during computational tasks.

On-Die ECC and Reliability Enhancement

The DDR5 architecture incorporates on-die ECC that corrects errors within the DRAM chips before data is transmitted to the system ECC. This two-tier error correction approach provides unprecedented reliability for mission-critical applications. The combination of on-die ECC and system-level ECC creates a robust error management system capable of handling both internal DRAM errors and transmission errors, significantly increasing mean time between failure rates.

DDR5 Technological Advancements

The transition to DDR5 technology brings several architectural enhancements including a dual 32/40-bit channel architecture per module, doubling the effective channel count compared to DDR4. This design increases concurrent access capabilities and improves overall memory efficiency. The command/address bus operates at a reduced voltage with separate power supply, enhancing signal integrity while reducing power consumption. These collective improvements deliver approximately 50% greater performance at improved power efficiency compared to equivalent DDR4 modules.

Application and Use Case Scenarios

Enterprise Server Applications

The high-density 64GB capacity and advanced reliability features make the 370-BBRX ideal for virtualization environments where memory availability directly impacts virtual machine density and performance. In cloud infrastructure deployments, these modules provide the consistent performance and error correction necessary for multi-tenant environments where hardware resources are shared across multiple clients and applications. The combination of capacity and reliability reduces the total cost of ownership through improved consolidation ratios and reduced downtime.

Database and Transaction Processing

For database servers handling OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) workloads, the 5600MT/s speed and ECC protection ensure data integrity during high-volume transaction processing. The module's bandwidth capabilities accelerate query performance for in-memory databases, while the registered design maintains stability during sustained heavy access patterns. These characteristics are particularly valuable for financial, e-commerce, and enterprise resource planning systems where data accuracy and system availability are paramount.

High-Performance Computing 

In technical computing environments such as scientific research, engineering simulation, and financial modeling, the 370-BBRX delivers the performance and capacity required for large dataset manipulation. The high bandwidth facilitates faster computation times for memory-bound algorithms, while ECC protection ensures computational accuracy throughout extended processing sessions. These capabilities are essential for applications where both performance and result validity are critical considerations.
