Compatible ASUS 1U Server Memory Kit

This 384GB DDR5 4800 ECC RDIMM kit is built for the ASUS RS700-E11-RS12U dual-socket 1U server. It supplies twelve 32GB registered modules that run at 1.10V with a CL40 latency. The memory is validated for the specific platform to ensure stable operation in mission-critical environments.

Suited for Maximum-Capacity 1U Deployments

The kit targets administrators who need the full 384GB capacity supported by the RS700-E11-RS12U chassis. It is not intended for systems that cannot accept twelve 288-pin RDIMMs or that require unbuffered memory. Buyers who need a smaller footprint or lower total capacity should select a different configuration.

12x32GB Registered DDR5 at 4800 MT/s

The single specification that determines fit is the twelve-module, 1Rx4 registered DDR5 4800 layout. Only motherboards qualified for this exact population and speed will recognise the full 384GB without down-clocking or slot limitations. Verify the server memory QVL before purchase.

Questions about this item

How do I install the 12 DDR5 RDIMMs into the ASUS RS700-E11-RS12U and what step is often missed?

Power off the server, open the chassis, and seat each 288-pin module fully until the ejector clips lock; the step most often missed is populating all twelve slots in the exact channel order shown in the ASUS service guide so the 384 GB kit runs at 4800 MT/s.

What maintenance or replacement will the 1Rx4 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so routine maintenance is limited to keeping server airflow clean; replacement is only required if a module fails ECC correction, which the lifetime warranty covers.

What limit appears first when the 384 GB kit runs sustained workloads at 4800 MT/s?

The 1.10 V operating voltage and CL40 latency are fixed by JEDEC DDR5 spec, so the first limit under sustained load is the memory controller’s thermal throttle point, not the RDIMMs themselves.
