32GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit delivers 32GB of DDR5 4800 memory as two 16GB registered DIMMs. It is built for the ASUS K14PA-U12 server motherboard supporting 128-core AMD EPYC 9004 processors. The modules run at 1.1V with CL40 latency and include on-die ECC for data integrity.

Suited for ASUS K14PA-U12 server upgrades

Ideal for administrators expanding memory in the specified ASUS server platform where registered ECC DDR5 is required. Not for desktop boards that accept only unbuffered non-ECC modules or systems limited to other DDR generations. Buyers needing different capacities or speeds should verify their motherboard documentation first.

Registered ECC DDR5 with 1Rx8 organisation

The decisive specification is the registered ECC DDR5 design with 1Rx8 rank structure at 4800 MT/s. This combination determines compatibility with the target ASUS server motherboard and the AMD EPYC 9004 platform. Confirm your system requires registered DDR5 RDIMMs before ordering.

Questions about this item

Does the ASUS K14PA-U12 motherboard need to support DDR5 4800 ECC Registered RDIMMs for this kit to function?

Yes, this kit requires a motherboard that accepts 288-pin DDR5 ECC Registered RDIMMs at 4800 MT/s with CL40 timing and 1.1 V operation.

Can the two 16 GB modules in this kit run in the same server as other RDIMMs of different capacities or speeds?

The motherboard and CPU memory controller determine mixed-DIMM rules; the EPYC 9004 platform generally allows mixed capacities per channel if all modules are registered ECC DDR5, but speeds will drop to the slowest installed DIMM.

After installation, how can I verify the system recognises both 16 GB modules at the rated 4800 MT/s with ECC active?

Check the BIOS memory information screen or run a tool such as dmidecode to confirm 32 GB total, 4800 MT/s speed, CL40 latency, 1.1 V voltage and ECC enabled on each DIMM.
