NEMIX RAM 128GB DDR5 4800 ECC RDIMM 4Rx4 CL40 1.1V HPE Compatible memory upgrade

HPE Server Memory Upgrade

This 128GB DDR5 RDIMM is built for HPE server and workstation platforms that require registered ECC memory. It targets IT professionals who need to expand capacity in compatible systems using a single high-density module. The part is validated for the HPE P43334-K21 specification and ships new from NEMIX RAM.

Thermals Noise and Power

Operating at 1.10V, the module draws low power for its density and runs without a heat spreader. Registered buffering and ECC functionality add negligible latency overhead while maintaining signal integrity under sustained server workloads. No active cooling is required beyond standard chassis airflow.

Deciding Specification 4Rx4 Rank Configuration

The 4Rx4 organisation determines whether the memory controller can address this module at the rated 4800MT/s speed. Systems limited to dual-rank or single-rank DIMMs will not support the full capacity or may fall back to a lower data rate. Verify the platform rank limit before purchase.
