ASUS Server DDR5 4800 ECC RDIMM

This 64GB DDR5 4800 ECC Registered DIMM is built for the ASUS K14PA-U12 motherboard running 128 core AMD EPYC 9004 processors. It targets administrators who need validated, single-module capacity expansion in mission-critical server environments. The module operates at 1.10V with CL40 latency and a 2Rx4 rank structure.

288-Pin Registered Design with Major OEM Chips

The registered buffer reduces electrical load on the memory controller, enabling stable operation in high-density configurations. Chips are sourced from Samsung, Micron or Hynix depending on supply, and the stick ships without a heat spreader to fit tight server DIMM spacing. The 288-pin DDR5 keying prevents accidental insertion into incompatible slots.

Single-Module Upgrade Kit for Targeted Expansion

The package contains one 64GB module, allowing precise capacity increments without populating unnecessary slots. Rigorous stress testing under load is performed before shipment to verify reliability in the qualified ASUS platform. This approach suits IT teams who add memory in measured steps rather than full-bank replacements.
