System-specific DDR5 kit

This NEMIX RAM kit delivers 256 GB of DDR5 4800 registered ECC memory across four 64 GB modules. It is built for the ASUS RS720-E11-RS24U 2U dual-socket server where system-specific validation is required.

Registered ECC with 2Rx4 organisation

The modules run at 1.10 V with CL40 latency and a 2Rx4 rank layout, providing error correction and signal buffering that the platform’s memory controller expects. This specification determines whether the server will POST and operate stably.

Four-slot population in a 2U chassis

Populating four DIMM slots with this kit leaves remaining slots free for future expansion while the registered design reduces electrical load on the memory bus. Buyers needing higher capacity per module or non-ECC memory for desktop platforms should look elsewhere.

Questions about this item

What does 4800 MT/s DDR5 actually deliver inside an ASUS RS720-E11-RS24U server?

The kit runs at the JEDEC-standard DDR5 4800 speed with CL40 latency, giving the maximum baseline bandwidth the platform supports without overclocking.

How does the registered ECC RDIMM interface affect usable capacity and stability?

Registered buffering and on-die ECC let the memory controller address all 256 GB reliably, correcting single-bit errors and reducing electrical load on the CPU memory bus.

Will the 288-pin DDR5 modules fit the RS720-E11-RS24U's DIMM slots without a heat-spreader clearance issue?

Yes, the bare 288-pin RDIMMs match the server's DDR5 slots exactly and have no heat spreader to interfere with the 2U chassis airflow path.
