256GB DDR5 ECC RDIMM kit for ASUS EPYC 9004 servers

This NEMIX RAM kit provides 256GB of registered DDR5 memory across four 64GB modules. It is built for the ASUS K14PA-U12 motherboard running AMD EPYC 9004 processors. The ECC registered design targets data integrity in mission-critical server workloads.

DDR5 4800 CL40 registered DIMM constraints

The modules operate at DDR5 4800 with a CAS latency of 40 and 1.10V voltage. The 2Rx4 organisation and registered buffer add latency versus unbuffered memory. Maximum capacity and speed depend on the motherboard memory controller and populated slot count.

Four-module installation on a 128-core platform

Installing four 288-pin RDIMMs follows standard server DIMM seating procedure. The K14PA-U12 board for 128-core EPYC 9004 CPUs has specific population rules; incorrect slot order will prevent boot or reduce performance. Always consult the motherboard manual for the validated sequence.

Questions sur cet article

Should I choose the 4×64 GB kit or a different capacity for the ASUS K14PA-U12?

The 4×64 GB kit delivers 256 GB total, matching the 12-channel design of the EPYC 9004 platform for full bandwidth.

What does the 4800 MT/s rating mean once the modules are installed in the server?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, providing the rated throughput when populated across all 12 memory channels.

How does the 288-pin RDIMM interface limit performance on this motherboard?

The registered 288-pin DDR5 RDIMM interface supports ECC and 2Rx4 organisation, capping each module at the JEDEC-standard 4800 MT/s data rate.
