384GB DDR5 ECC RDIMM kit for ASUS EPYC 9004 servers

This twelve-module kit delivers 384GB of registered DDR5 memory at 4800 MT/s for the ASUS K14PA-U12 motherboard. It targets administrators expanding 128-core AMD EPYC 9004 platforms where ECC integrity and high density are mandatory for virtualisation or database workloads.

Compatibility checklist for the K14PA-U12 platform

Verify that the motherboard firmware revision supports 1Rx4 registered DIMMs at the full 4800 MT/s data rate across all twelve slots. Confirm the CPU memory-controller configuration allows the full 384GB capacity without downclocking. Ensure the chassis airflow path can accommodate the module height without cable interference.

Thermals noise and power at 1.1 V DDR5 baseline

Operating at 1.10 V, the modules run within standard DDR5 server power envelopes and produce no audible noise as they have no moving parts. Passive cooling relies on case airflow; no heat spreader is fitted so directed airflow over the DRAM packages is required. Power draw scales with all twelve ranks active under sustained load.
