Server memory kit for ASUS K14PA-U12

This NEMIX RAM kit provides 384GB of DDR5 4800 ECC registered memory across six 64GB modules. It is built for the ASUS K14PA-U12 motherboard supporting 128 core AMD EPYC 9004 processors. The 2Rx4 organisation and CL40 latency suit enterprise workloads that demand data integrity and high capacity.

Verify motherboard and CPU compatibility

Confirm the system uses the ASUS K14PA-U12 motherboard and an AMD EPYC 9004 series processor before ordering. The kit requires twelve 288-pin DDR5 RDIMM slots populated in a six-module configuration. Ensure the platform firmware supports registered ECC modules at 1.1V operating voltage.

Six matched modules simplify deployment

The package contains six 64GB modules tested together for the target platform. This removes the need to source individual sticks and reduces the risk of mixed-rank or timing mismatches. No heat spreaders are included, so airflow in the server chassis must be adequate for bare modules.
