16 GB DDR5 ECC RDIMM for ASUS 2U server

This 16 GB DDR5 4800 module is a registered ECC RDIMM built for the ASUS RS720-E11-RS12U 2U dual-socket server. It runs at 1.1 V with CL40 latency and a 1Rx8 organisation. The 288-pin form factor fits the platform's memory slots directly.

Who this suits and who it does not

It suits administrators upgrading or repairing the named ASUS 2U server where registered ECC DDR5 is required. It is not for desktop or consumer motherboards that accept only unbuffered non-ECC memory, nor for systems that need a different speed, voltage or pin layout.

Deciding specification: registered ECC DDR5 RDIMM

The module is a registered ECC DDR5 RDIMM, so it will only work in platforms that explicitly support registered ECC DDR5 memory. Verify the server's qualified vendor list before purchase.

Questions about this item

Will the 1Rx8 registered ECC module need replacement if a memory channel fails?

The module is a single 16 GB DDR5 4800 CL40 1Rx8 registered ECC RDIMM. ECC corrects single-bit errors on the fly, and registered signalling reduces electrical load on the memory controller. No scheduled replacement is required; the module runs at 1.1 V for its service life.

What limit appears first when the RDIMM runs continuously at DDR5 4800?

Sustained operation at 4800 MT/s is bounded by the CL40 latency and 1.1 V supply. The registered buffer and on-die ECC keep signal integrity within spec, so the first ceiling is the rated speed and timing rather than thermal or voltage headroom.

How much heat and noise does the 288-pin DDR5 RDIMM produce in a 2U server running all day?

The module has no heat spreader and draws 1.1 V at 4800 MT/s. Power stays within standard DDR5 RDIMM limits, so it adds minimal heat to the server airflow and generates no audible noise of its own.
