System-specific DDR5 ECC RDIMM kit

This 256 GB kit contains two 128 GB registered DDR5 modules built for the ASUS RS700-E11-RS12U 1U dual-socket server. Each module runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.10 V. The 4Rx4 organisation and on-die ECC protect data integrity in mission-critical workloads.

Thermals power and acoustics

The modules have no heat spreader, relying on the server’s directed airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep system power draw predictable under sustained load. Silent operation is inherent because no active cooling is attached to the DIMMs themselves.

What the kit changes

Installing the matched pair populates two slots with validated capacity, eliminating guesswork about rank interleaving or voltage compatibility. The pre-tested 288-pin RDIMM format ensures the server recognises the full 256 GB at POST without manual timing adjustments.

Perguntas sobre este artigo

How do I install the 288-pin DDR5 RDIMM modules in the ASUS RS700-E11-RS12U server, and what step is often missed?

Power down the server, open the chassis, align each 128GB module with the DDR5 slot key, press firmly until the ejector clips lock, then verify in BIOS that both 4Rx4 modules are detected at 4800 MT/s.

What maintenance or replacement will the registered ECC DDR5 kit need during its service life?

The modules have no heat spreaders and no moving parts; run periodic memory diagnostics and keep firmware current — no scheduled replacement is required unless a module fails ECC correction.

What limit appears first when the 256GB kit runs sustained workloads at 1.1V CL40?

The CAS 40 latency and 4Rx4 rank density set the throughput ceiling; sustained bandwidth is capped by the DDR5 4800 MT/s rating and the server memory controller.
