128GB DDR4 Registered DIMM Technology

The HPE 819415-001 represents a significant advancement in server memory technology with its massive 128GB capacity per module. This high-density DDR4 registered memory utilizes advanced 16Gb DRAM components arranged in a sophisticated multi-rank configuration to achieve unprecedented memory density in a standard form factor. The module operates at 2400MHz with PC4-19200 designation, delivering exceptional bandwidth of 19,200 MB/s per module while maintaining the reliability and compatibility expected from HPE's enterprise memory solutions. The 128GB capacity enables organizations to dramatically reduce the physical footprint required for large memory configurations, making it ideal for memory-intensive applications and high-density server deployments.

Registered Memory for High Density

The registered design of the 819415-001 is essential for supporting the high component count and electrical load of 128GB capacity. Each module incorporates a Registering Clock Driver (RCD) that buffers command, address, and control signals between the memory controller and the numerous DRAM chips. This buffering reduces the electrical load on the memory controller, enabling stable operation at 2400MHz despite the massive capacity. The architecture typically employs a multi-rank design (often quad-rank) that organizes the memory into multiple logical units that can be accessed independently, improving memory access efficiency and overall system performance.

Speed and Timing Characteristics

Operating at 2400MHz with PC4-19200 classification, the HPE 819415-001 delivers substantial memory bandwidth while maintaining excellent signal integrity. The CAS Latency timing is optimized for server workloads, typically operating at industry-standard timings for this capacity and speed class. The 1.2V operation represents significant power efficiency compared to previous generation memory technologies, while advanced power management features dynamically adjust power consumption based on workload demands. This combination of high capacity and respectable speed makes the module ideal for memory capacity-bound applications where total available memory is more critical than peak bandwidth.

Bandwidth and Capacity Advantages

With its 2400MT/s data rate and 128GB capacity, the 819415-001 enables massive memory configurations in space-constrained environments. A single server can support multiple terabytes of memory using these high-density modules - for example, an 8-socket system with 24 DIMM slots per socket could theoretically support up to 24TB of memory. The 19.2 GB/s bandwidth per module aggregates across memory channels to provide substantial total system bandwidth, though the primary advantage of these modules lies in their capacity density rather than peak bandwidth per module.

Error Correcting Code Implementation

The HPE 819415-001 incorporates sophisticated Error Correcting Code technology that provides comprehensive protection against memory errors. The ECC implementation can detect and correct single-bit errors while detecting multi-bit errors, ensuring data integrity for critical business applications. For high-density modules like the 128GB configuration, ECC protection is particularly important due to the increased statistical probability of memory errors across the larger number of memory cells. The module works in conjunction with supported server platforms to implement advanced error management features that proactively identify and address potential reliability issues before they impact system operation.

Single Device Data Correction (SDDC) Capability

Beyond standard ECC functionality, the 819415-001 supports Single Device Data Correction (SDDC) when used in compatible HPE ProLiant servers. This advanced error correction capability, sometimes referred to as Chipkill technology, can correct errors resulting from the complete failure of an individual DRAM chip. This level of protection is crucial for mission-critical applications and large memory configurations where the impact of memory errors could be catastrophic. The SDDC functionality works transparently without performance degradation, providing an additional layer of data protection for enterprise workloads.

Proper configuration ensures that systems can leverage the full capacity of these high-density modules while maintaining stable operation at rated speeds.

Memory Configuration Best Practices

When configuring systems with 128GB modules, specific population rules must be followed to ensure optimal performance and compatibility. High-density modules typically have different electrical characteristics than lower-density modules, which can impact signal integrity and maximum supported speed. HPE's population guidelines specify the optimal configuration for mixing different density modules and the maximum number of high-density modules that can be installed per channel while maintaining rated speeds. Following these guidelines is essential for achieving stable operation and maximizing system performance.

Mixed Density Configuration Considerations

While the 819415-001 can be mixed with other HPE-certified DDR4 memory modules in supported systems, careful planning is required to ensure optimal performance. Mixing different memory densities within the same channel may impact performance or require the system to operate all memory at lower speeds. HPE provides comprehensive configuration tools and compatibility matrices to assist with planning mixed-density memory configurations. The UEFI System Utilities in compatible servers provide validation and reporting of memory configuration during system initialization.
