This engineering excellence ensures reliable performance even in fully populated memory configurations.

Performance Specifications and Capabilities

The HPE 819415-001 operates at 2400MHz with a PC4-19200 designation, delivering substantial memory bandwidth of 19,200 MB/s per module. While the raw speed of 2400MHz represents the mainstream performance tier for high-capacity DDR4 modules, the enormous 128GB capacity transforms the performance equation by enabling massive working sets to reside entirely in memory. The module's timing configuration is optimized for high-density operation, balancing latency characteristics with the extensive electrical load presented by the large memory array. This combination of substantial capacity and respectable speed makes the module ideal for memory capacity-bound applications rather than pure bandwidth-limited workloads.

Massive Memory Capacity Advantages

The 128GB capacity per module enables revolutionary memory configurations that were previously impossible or cost-prohibitive. A standard two-socket server can support up to 4TB of memory using 32 of these modules, while eight-socket systems can achieve staggering 8TB configurations. This massive memory capacity eliminates the need for complex memory paging strategies and enables entire multi-terabyte datasets to reside in main memory. The performance impact of keeping large working sets in memory rather than swapping to storage can be orders of magnitude, particularly for in-memory databases, large-scale virtualization, and big data analytics applications.

Enhanced Error Correction Capabilities

The HPE 819415-001 implements sophisticated Error Correcting Code technology specifically engineered for high-density memory configurations. The module supports single-bit error correction and double-bit error detection across the entire 128GB address space, maintaining data integrity even with the increased statistical probability of errors in larger memory arrays. In compatible HPE ProLiant systems, the memory controller implements advanced ECC algorithms that can correct more complex error patterns, including certain multi-bit errors that might occur in high-density memory environments. This robust error protection is essential for mission-critical applications where data corruption could have severe consequences.

Memory Mirroring and Sparing

When used in supported HPE server platforms, the 819415-001 enables advanced reliability features including memory mirroring and sparing. Memory mirroring maintains identical copies of data in separate memory channels, providing continuous operation even if an entire memory module fails.
