NEMIX RAM
16 GB DDR4 3200 ECC registered DIMM for HPE servers, CL22 1.2 V 288-pin
This 16GB DDR4 3200 ECC RDIMM module is designed for HPE server and workstation platforms. It targets IT professionals maintaining compatible enterprise systems that require registered memory with error correction. The single 1Rx4 rank configuration fits standard 288-pin DDR4 slots in validated HPE hardware.
Registered DDR4 3200 modules operate at 1.2V with CL22 latency and PC4-25600 bandwidth. The registered buffer adds one clock cycle of latency, which is standard for ECC RDIMM topology and limits maximum usable frequency on some platforms. Population rules for specific HPE models may restrict total capacity per channel or require matched ranks across controllers.
The module uses major OEM Samsung, Micron or Hynix chips on a bare PCB without a heat spreader. Standard 288-pin RDIMM keying ensures mechanical compatibility with server DIMM slots that accept registered modules. The low-profile design assists airflow in dense chassis, while the lack of a spreader means thermal monitoring relies on platform sensors.

The 1Rx4 organisation is the one specified for the HPE P06029 series; matching that rank keeps the memory subsystem balanced.
The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V, providing the rated throughput the platform expects.
The 288-pin registered DDR4 form factor caps operation at the JEDEC 3200 MT/s standard and 16 GB per module in this configuration.
