64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for the ASUS K14PA-U12 server motherboard supporting 128-core AMD EPYC 9004 processors. IT teams upgrading memory in that specific platform will find the modules validated for the workload.

Tool-free DIMM installation

Installation follows the standard 288-pin DDR5 RDIMM procedure: open the socket latches, align the module key, press until the latches click, and repeat for all four slots. The most common issue is mixing registered ECC modules with unbuffered or non-ECC DIMMs, which prevents the system from posting.

Verify motherboard and CPU first

Confirm the board is the exact ASUS K14PA-U12 model and that the installed processors are AMD EPYC 9004 series. The platform requires registered ECC DDR5 at 1.1V; any other memory type will not be recognised. Check the server manual for the supported population order across the 12 memory channels.
