HPE 879505-B21 8GB DDR4 Memory Module backup drive

Server Memory Module

This HPE 879505-B21 module adds 8GB of DDR4 memory to compatible entry-level HPE servers. It is intended for small and medium business owners who need enterprise-quality memory to support workloads while controlling capital and operating expenses. The module undergoes rigorous testing and authentication to ensure full compatibility and optimisation for the target platforms. It is sourced from high-quality DRAMs rather than third-party alternatives.

DDR4-2666 MT/s Speed

The decisive specification is the 2666 MT/s data rate, which determines whether this module matches the memory bus of your server platform. HPE Gen10 servers support up to 16 GB DDR4-2666 MT/s memory options, so this 8GB module fits within that supported configuration. If your platform requires a different speed or generation, this module will not function correctly. Verify the required memory speed before purchase.

Sustained Workload Reliability

Under sustained load the module maintains the performance and reliability validated by HPE's extensive testing process. The authentication procedure ensures consistent operation at industry-defined specifications during continuous workloads. Unlike unvalidated alternatives, this memory is optimised for the thermal and electrical conditions of entry-level HPE server platforms over long periods. It delivers stable throughput without the variability seen in non-authenticated modules.
