This high-speed performance enables faster data access and processing capabilities for memory-intensive applications.

Timing and Voltage Characteristics

This RDIMM operates with CAS Latency (CL) 22 timing parameters at the specified 3200MHz frequency. The module requires a standard operating voltage of 1.2V, consistent with DDR4 technology specifications. The timing configuration of CL22 represents the optimal balance between speed and stability for server-grade memory, ensuring reliable performance under continuous operation conditions while maintaining compatibility with Dell PowerEdge server platforms.

ECC Registered Technology

The Dell 370-BBQP incorporates Error Correcting Code (ECC) technology, which provides advanced error detection and correction capabilities. This critical feature automatically detects and corrects single-bit memory errors while detecting multi-bit errors. The ECC functionality significantly enhances system reliability and data integrity, making this memory module ideal for mission-critical applications where data accuracy is paramount. The registered design includes a register buffer that reduces electrical load on the memory controller, enabling support for higher memory capacities and improved signal integrity.

Registered DIMM Advantages

As a Registered DIMM (RDIMM), this memory module includes a register between the memory controller and DRAM chips. This architecture provides several advantages for server environments, including improved signal integrity, reduced electrical load on the memory controller, and support for higher memory densities. The registered design enables more stable operation with multiple modules installed and allows for larger overall memory configurations in supported Dell PowerEdge servers.

Dual Rank x4 Architecture

Rank Configuration Benefits

The 2Rx4 (Dual Rank x4) configuration indicates that the memory module contains two separate ranks of memory chips, with each chip having a 4-bit data interface. This architecture provides performance benefits by allowing the memory controller to access one rank while preparing the other rank for the next operation. The dual rank design increases memory efficiency and can provide better performance compared to single-rank modules in many server workloads, particularly in multi-processor configurations.

Data Organization and Access Patterns

The x4 organization refers to the internal data width of each DRAM chip, where each chip provides 4 bits of data per access. This configuration is particularly beneficial for server applications as it provides better reliability characteristics and more efficient use of error correction resources. The x4 architecture also enables more optimal memory chip organization on the module, contributing to the overall stability and performance characteristics essential for enterprise server environments.

Module Form Factor

288-Pin DIMM Structure

The Dell 370-BBQP utilizes the standard 288-pin RDIMM form factor specifically designed for server platforms. The physical dimensions conform to industry standards for DDR4 server memory, measuring approximately 133.35mm in length and 31.25mm in height. The module features a single notch position located differently from DDR3 modules to prevent accidental insertion into incompatible motherboards. The 288-pin design provides the necessary signal lines for data transfer, addressing, command, and control functions required for high-performance server memory operations.

PCB and Component Layout

The printed circuit board (PCB) is constructed with high-quality materials and multiple layers to ensure signal integrity and thermal performance. Memory chips are arranged on both sides of the PCB in accordance with the dual-rank configuration. The module includes necessary passive components, such as resistors and capacitors, for signal termination and power filtering. The physical design incorporates thermal considerations to ensure stable operation under continuous server workloads.

Dell PowerEdge Server Compatibility

The Dell 370-BBQP memory module is specifically validated and tested for compatibility with various Dell PowerEdge server platforms. This module is designed to work with multiple generations of Dell servers that support DDR4 technology and the specific speed grade of 3200MHz. Compatibility includes but is not limited to select models of Dell PowerEdge rack servers, tower servers, and modular infrastructure. Users should consult the specific server documentation and Dell compatibility matrices to ensure proper support for their particular server model and configuration.

Speed and Bandwidth Capabilities

Operating at 3200MT/s (MegaTransfers per second), the Dell 370-BBQP delivers a peak theoretical bandwidth of 25,600 MB/s per module. This high-speed operation enables faster processing of memory-intensive workloads and reduces potential bottlenecks in data access. The PC4-25600 designation indicates the module's capability to transfer 25.6 gigabytes of data per second under ideal conditions. This performance level supports demanding applications including database management, virtualization, high-performance computing, and enterprise applications.

Latency Characteristics

The CAS Latency of 22 clock cycles at 3200MHz represents the time delay between when a memory controller requests data and when it becomes available. While the absolute latency in nanoseconds is comparable to lower-speed modules with tighter timings, the higher data rate provides greater overall bandwidth. The specific timing parameters are optimized for server workloads where reliability and sustained performance are more critical than ultra-low latency characteristics typically required in desktop gaming scenarios.

Reliability and Stability Features

Enterprise-Grade Reliability

This memory module is engineered for 24/7 operation in enterprise environments where reliability is critical. The components are selected and tested to meet Dell's stringent quality standards for server memory. The module undergoes extensive testing and validation to ensure compatibility and reliability in Dell PowerEdge servers. This includes thermal testing, signal integrity validation, and compatibility testing across various server configurations and firmware versions.

Application and Use Cases

Server Workload Optimization

The 64GB capacity and ECC features make the Dell 370-BBQP ideal for virtualization platforms where multiple virtual machines share physical memory resources. The high density allows for greater virtual machine density per server, while ECC protection ensures data integrity across virtualized workloads. The 3200MHz speed provides responsive performance for memory-intensive virtualized applications, and the registered architecture supports the large memory configurations required for enterprise virtualization deployments.

Database and Transaction Processing

For database servers and online transaction processing systems, the combination of high capacity, ECC protection, and 3200MHz speed delivers the performance and reliability required for critical business applications. The large 64GB module size enables substantial database caching in memory, reducing disk I/O and improving query performance.
