Operating at 5600MT/s (MegaTransfers per second), the Dell 370-BCHN delivers exceptional data throughput capabilities. This speed rating translates to a peak transfer rate of 5600 million data transfers per second per module. The PC5-44800 designation indicates the module's bandwidth rating of 44800 MB/s per module, providing aggregate system bandwidth that scales linearly with the number of modules installed in the server configuration.

Timing Parameters and Latency

The memory operates with CAS Latency (CL46) timing parameters, optimized for server workloads where consistency and reliability take precedence over ultra-low latency. The CL46 timing represents 46 clock cycles between column address strobe and data availability, carefully balanced against the high operating frequency to deliver optimal performance for enterprise applications and data-intensive computing tasks.

Advanced Memory Features

Featuring Error Correcting Code (ECC) technology, the Dell 370-BCHN provides essential data integrity protection for critical server environments. ECC functionality enables the memory to detect and correct single-bit errors automatically, while also detecting multi-bit errors. This capability prevents data corruption and system crashes that can result from memory errors, ensuring continuous operation and data reliability in 24/7 enterprise environments.

Registered Memory Advantages

As a Registered DIMM (RDIMM), this memory incorporates register chips between the memory controller and DRAM modules. These registers buffer address, command, and control signals, reducing electrical load on the memory controller and enabling support for higher memory capacities per channel. The registered design enhances signal integrity and system stability, particularly important in multi-processor systems with large memory configurations.

Power Management and Efficiency

Voltage Specifications and Power Consumption

Operating at 1.1V, the Dell 370-BCHN demonstrates significant power efficiency improvements compared to previous memory generations. The reduced operating voltage contributes to lower power consumption and reduced heat generation, while maintaining signal integrity through advanced power delivery circuitry. This efficiency translates to reduced total cost of ownership through lower energy consumption and decreased cooling requirements in data center environments.

Power Management Integrated Circuit

DDR5 technology introduces the Power Management Integrated Circuit (PMIC) on each memory module, a significant advancement over previous generations. The PMIC distributes power more efficiently to various components on the DIMM, providing better power delivery and noise reduction. This onboard power management enables more stable operation and improved reliability under varying load conditions.

Dual Rank Architecture (2RX8)

The 2RX8 designation indicates a dual-rank configuration with an x8 DRAM device organization. Each module contains two independent ranks that can be accessed separately, improving memory efficiency by allowing overlapping operations between ranks. The x8 organization refers to the internal architecture of the memory chips, providing optimal balance between capacity, performance, and reliability for server applications.

Memory Channel Optimization

When installed in compatible server platforms, the 8-module kit enables optimal memory channel population across multiple processors. This configuration maximizes memory bandwidth by ensuring balanced loading across all available memory channels, reducing bottlenecks and improving overall system performance for memory-intensive applications and virtualized environments.

Signal Integrity and Reliability

On-Die ECC Implementation

Beyond traditional ECC protection, DDR5 memory incorporates On-Die ECC that corrects errors within the DRAM chips themselves before data is transmitted to the memory controller. This additional layer of error correction improves reliability and extends the usable life of the memory by correcting minor errors that occur within the memory cells, providing comprehensive data protection throughout the memory subsystem.

Application and Use Case Scenarios

Enterprise Workload Optimization

The Dell 370-BCHN 256GB kit excels in database management systems and online transaction processing environments where large memory capacities and ECC protection are essential. The high capacity enables larger database caching, reducing disk I/O and improving transaction throughput. The reliability features ensure data integrity for critical business transactions and financial operations.
