Server Memory Kit

This 768GB kit contains six 128GB DDR5 4800 CL40 ECC RDIMM modules built for the ASUS K14PA-U12 motherboard. Registered buffering and on-die error correction protect data integrity in multi-socket EPYC 9004 platforms running 128 cores. The 1.1V operating voltage matches the DDR5 server standard. Modules use major OEM Samsung Micron Hynix components and carry part number MR38400-744K6.

Suited for Dense Workloads

Administrators expanding memory capacity on the named ASUS server board for virtualisation databases or high-performance computing will match the qualified configuration. Builders using different motherboards processor families or unbuffered DIMM slots cannot install these registered modules. Systems requiring lower latency timings or higher DDR5 speeds should evaluate alternative kits validated for their specific platform.

Ready to Install Package

The kit delivers six matched 288-pin RDIMMs in a single package so all channels populate identically without mixing lots. No heat spreaders are included relying on server chassis airflow for thermal management. No software utilities or firmware tools accompany the memory; configuration is handled through the system BIOS. Lifetime replacement warranty and US-based technical support are provided by the manufacturer.

Questions about this item

Will this kit work with my ASUS K14PA-U12 server motherboard?

The kit is built for the ASUS K14PA-U12 and supports 128-core AMD EPYC 9004 processors.

Can I keep existing DDR5 4800 ECC RDIMMs installed alongside these new modules?

The new modules are 4Rx4 registered ECC DDR5 4800 at 1.10V; matching speed, voltage and rank is required for stable operation.

How do I verify the full 768 GB is recognised after installation?

Check the BIOS memory map or OS tools — all six 128 GB modules should appear at DDR5 4800 with CL40 timings.
