128 GB DDR5-4800 ECC registered RDIMM with 2Rx4 organisation for HPE-compatible servers
This 128GB DDR5-4800 registered ECC RDIMM targets enterprise servers that require maximum memory density per slot. The dual-rank 2Rx4 organisation delivers high capacity while maintaining signal integrity through the registered buffer. It is built for workloads such as virtualisation, in-memory databases and large-scale analytics where error correction and stability are mandatory.
The module uses a major-brand chipset and matches HPE part number P69982-B21 for drop-in compatibility with qualified platforms. Registered signalling reduces electrical load on the memory controller, allowing dense population across all available DIMM slots without timing degradation. Identical modules ship together to ensure consistent performance in multi-channel configurations.
Operating at 4800 MT/s (PC5-38400), the DDR5 architecture provides higher bandwidth and improved power management compared with previous generations. On-die ECC and registered buffering help maintain data integrity under sustained load while the efficient voltage regulation limits thermal output in fully populated chassis. The design supports continuous operation in dense server environments.
