1.5TB DDR5 ECC RDIMM kit for ASUS servers

This 1.5TB kit contains twelve 128GB DDR5 registered DIMMs built for ASUS 2U4N high-density immersion-cooling servers. It targets IT professionals who need maximum memory capacity in a validated server configuration. The modules operate at 1.1V with CL40 latency and include on-die ECC for data integrity. Buyers needing non-ECC memory or consumer desktop DIMMs should look elsewhere.

4800MT/s PC5-38400 registered DDR5

The decisive specification is the DDR5 4800 registered ECC RDIMM format with 4Rx4 rank architecture. This combination determines compatibility with the ASUS RS720Q-E11-IM platform and similar qualified server boards. The 288-pin registered interface and on-die error correction are mandatory for the target system; unbuffered or non-ECC modules will not function in this environment.

128GB modules provide 1.5TB total across twelve

Twelve 128GB modules fill every available DIMM slot on the compatible ASUS server, delivering 1.5TB of addressable memory for virtualisation, in-memory databases and high-performance computing workloads. Capacity headroom ends when all twelve sockets are populated; further expansion requires a platform with additional memory channels or higher-density modules not included in this kit.

Questions about this item

What does the 4800 MT/s speed mean for actual throughput in this server?

The DDR5 4800 rating sets the maximum data rate each module can sustain; real-world throughput depends on the memory controller and workload.

How does the PC5-38400 designation limit performance in practice?

PC5-38400 confirms the 4800 MT/s transfer rate and defines the peak bandwidth envelope the platform cannot exceed.

Will the 288-pin 4Rx4 RDIMMs fit the ASUS RS720Q-E11-IM slots without clearance issues?

These 288-pin DDR5 RDIMMs match the server's DIMM sockets; the 4Rx4 organisation is supported by the platform.
