Server Memory Upgrade

This 64GB DDR5 ECC registered DIMM is built for HP ProLiant Gen11 servers including the DL325, DL345, DL360, DL365 and DL380. It provides error-correcting memory for workloads that require data integrity in workstations, NAS systems and network switches.

Sustained Load Behaviour

The module operates at 4800MHz with CL40 latency and a 1.1V supply, delivering consistent throughput for long-running server tasks. ECC registration corrects single-bit errors on the fly, preventing data corruption during extended compute or storage operations.

Thermals and Power

Without a heat spreader the DIMM relies on chassis airflow for cooling, keeping power draw low at the standard DDR5 voltage. The registered design reduces electrical load on the memory controller, helping maintain stable temperatures in densely populated server configurations.
