NEMIX RAM 128GB DDR5 4800 ECC RDIMM 4Rx4 CL40 HPE P43334-B21 memory upgrade

Targeted Server Upgrade

This NEMIX RAM module delivers 128GB of DDR5 ECC registered memory for HPE server and workstation platforms. The single DIMM format suits administrators who need to expand capacity in dense configurations without occupying additional slots. IT teams handling virtualisation, databases or large-scale compute workloads gain the density required for memory-intensive applications.

Registered Design and Pin Layout

The 288-pin RDIMM form factor uses a registered buffer to reduce electrical load on the memory controller, supporting stable operation in multi-DIMM populations. Operating at 1.10V, the module aligns with DDR5 power expectations for enterprise platforms. Absence of a heat spreader keeps the profile low for restricted airflow paths, while the 4Rx4 organisation maximises rank density per channel.

Decisive Specification

DDR5 4800 speed with CL40 latency and PC5-38400 bandwidth defines the throughput ceiling for this part. The 4Rx4 rank structure and ECC registration determine whether the motherboard memory controller can address the full 128GB capacity at rated frequency. Buyers who need higher frequencies or lower latencies must verify platform support before selecting this module.
