ASUS K14PA-U12 EPYC 9004 DDR5 Upgrade

This 128GB DDR5 4800 ECC RDIMM is built for the ASUS K14PA-U12 server motherboard running AMD EPYC 9004 processors. It targets administrators expanding memory in registered DIMM slots for mission-critical workloads. The single-module design simplifies population rules in high-density configurations. Compatibility is validated for this specific platform.

DDR5 4800 Registered ECC Limits

The module operates at DDR5 4800 (PC5-38400) with CL40 latency and 1.10V voltage. Registered buffering and ECC are mandatory for the platform; unbuffered or non-ECC DIMMs will not function. The 4Rx4 organisation increases electrical load per slot, which may restrict maximum populated speeds on fully loaded channels. No heat spreader is fitted, so chassis airflow must handle thermal dissipation.

128GB Single-Module Capacity Headroom

One 288-pin RDIMM delivers 128GB, allowing large per-slot density for virtualisation, databases or HPC datasets. Four ranks per module maximise capacity within the 12-channel EPYC 9004 architecture. Systems requiring more than 128GB per channel must add further modules, subject to the motherboard's slot count and rank limits. The 1.1V operating voltage helps contain power draw at this density.

商品問答

Should I pick the 128GB module or combine smaller sticks for the ASUS K14PA-U12?

The K14PA-U12 supports 128GB per slot, so a single 128GB 4Rx4 RDIMM fills one channel and leaves the other eleven channels free for future expansion.

What does the DDR5 4800 rating deliver on an EPYC 9004 system?

At 4800 MT/s the module runs at the processor's native memory speed, giving full bandwidth without down-clocking or overclocking.

How does the 288-pin RDIMM interface limit capacity on this board?

Each 288-pin slot accepts one registered DIMM; the 4Rx4 organisation lets this stick reach 128GB while staying within the electrical load the memory controller allows.
