System-Specific DDR5 Kit

This 256GB kit contains two 128GB DDR5 4800 registered ECC RDIMMs built for the ASUS RS720-E11-RS24U 2U dual-socket server. It targets administrators who need maximum capacity per slot in that platform. The modules are not compatible with consumer motherboards or systems that require unbuffered memory.

Thermals and Power

Each module operates at 1.10V with a CL40 latency and a 4Rx4 organisation. The registered buffer and on-die ECC add negligible latency overhead while correcting single-bit errors in flight. No heat spreader is fitted, so airflow across the DIMM slots must follow the server chassis design.

What the Kit Changes

The matched pair populates two slots with 256GB total, letting the RS720-E11-RS24U reach higher memory ceilings for virtualisation or in-memory databases. Registered signalling and ECC protect data integrity under sustained load. No additional software or accessories are included beyond the two modules.

商品問答

How do I install these 288-pin DDR5 RDIMMs in the ASUS RS720-E11-RS24U server, and what step is often missed?

Power down the server, open the chassis, and seat each 128 GB module firmly until the ejector clips lock; the step often missed is confirming the BIOS recognises both 4Rx4 ranks at 4800 MT/s before closing the case.

What maintenance or replacement will this 256 GB ECC registered kit need over its service life?

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

What limit appears first when the memory runs sustained workloads at 1.1 V?

The primary limit is the CL40 latency at 4800 MT/s; sustained throughput is bounded by the DDR5 38400 transfer rate and the registered buffer, not by thermal throttling, since the RDIMMs operate without heat spreaders.
