1TB DDR5 ECC RDIMM kit for ASUS EPYC 9004 servers

This 1 TB kit contains eight 128 GB DDR5 4800 registered DIMMs built for the ASUS K14PA-U12 motherboard and AMD EPYC 9004 processors. It targets administrators who need maximum registered ECC capacity in a single qualified package. The modules are validated for mission-critical server workloads that demand registered memory with error correction.

Registered DDR5 at 1.1 V with CL40 latency

Each module operates at the standard 1.10 V DDR5 voltage and runs at 4800 MT/s with a CAS latency of 40. The registered 4Rx4 organisation adds a buffer that reduces electrical load on the memory controller, supporting stable operation across all twelve channels of the EPYC 9004 platform. No heat spreader is fitted, so airflow in the server chassis handles thermal management.

Eight-module kit validated for twelve-channel

The package delivers eight matched 288-pin RDIMMs, allowing balanced population across the processor's memory channels. Rigorous stress testing under load is performed before shipment to verify compatibility and reliability in the target ASUS system. Major OEM DRAM from Samsung, Micron or Hynix is used depending on supply.

Questions about this item

How do I install the 8 DDR5 4800 RDIMM modules into the ASUS K14PA-U12 and which slot order does the manual require?

Populate all twelve DDR5 slots following the ASUS K14PA-U12 manual's channel sequence; seat each 288-pin RDIMM until the ejector tabs click, then verify 1 TB detected at POST.

What maintenance or replacement will the 128 GB 4Rx4 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers a direct swap of the defective 128 GB stick.

What limit appears first when the 1 TB DDR5 4800 CL40 kit runs sustained workloads on EPYC 9004?

The CL40 latency at 4800 MT/s sets the throughput ceiling; sustained loads will hit that timing boundary before voltage or thermal limits.
