Capacity and configuration

This 256 GB kit contains eight 32 GB DDR5 4800 ECC registered DIMMs built for the ASUS K14PA-U12 motherboard and AMD EPYC 9004 processors. The modules run at 1.1 V with CL40 latency and use a 1Rx4 organisation on 288-pin DDR5 RDIMM form factor.

Who this suits

IT teams deploying memory in the validated ASUS K14PA-U12 platform for 128-core EPYC 9004 servers will find a tested, compatible solution. Buyers who need a different motherboard, a non-ECC configuration, lower capacity per module, or a different speed grade should look elsewhere.

Deciding specification

The registered ECC DDR5 4800 1Rx4 288-pin design at 1.1 V is the single parameter that determines whether this kit matches the memory controller and slot requirements of the target server.

Questions about this item

Does the 8×32 GB kit include everything needed for the ASUS K14PA-U12, or are additional parts required?

The kit supplies eight 288-pin DDR5 RDIMM modules totalling 256 GB; no extra memory components are needed for the listed server board.

How do I choose between the 1Rx4 CL40 1.1 V modules and other DDR5 variants for this platform?

The EPYC 9004 memory controller on the K14PA-U12 is validated for 4800 MT/s registered ECC RDIMMs at 1.1 V with CL40 timing; this kit matches that specification exactly.

What does the 4800 MT/s rating mean once the modules are installed in the 128-core EPYC 9004 system?

Each module runs at 4800 MT/s with CL40 latency, providing the rated DDR5 throughput for the server's twelve memory channels.
