16GB DDR5 ECC RDIMM for ASUS S14NA-U12

This registered DDR5 module delivers 16GB of error-correcting memory at 4800MT/s with CL40 latency. It is built for the ASUS S14NA-U12 server board and uses 1Rx8 organisation on a 288-pin form factor. The 1.10V operating voltage matches the platform specification.

Thermals and power in normal use

The module runs at the standard 1.10V DDR5 voltage without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained workloads. ECC circuitry adds minimal overhead while correcting single-bit errors transparently.

Build integration and requirements

The single 288-pin RDIMM occupies one DIMM slot and requires a motherboard that supports registered ECC DDR5 at 4800MT/s. It frees remaining slots for identical modules to scale capacity in matched sets. Compatibility is validated for the ASUS S14NA-U12; other platforms need separate verification.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my ASUS S14NA-U12 server, and what step is often missed?

Power down the server, open the chassis, align the module key with the slot, press firmly until both retention clips click, then verify in BIOS that the 16 GB module is detected at 4800 MT/s with ECC active.

What maintenance or replacement will this 1.1 V registered ECC module need over its service life?

No scheduled maintenance is required; the module either runs indefinitely or is replaced if ECC correctable-error counters rise or a hard failure occurs.

What limit appears first when this CL40 1Rx8 module runs sustained workloads?

The DDR5 4800 MT/s data rate and CL40 latency set the throughput ceiling; the memory controller will throttle before the 1.1 V DRAM hits a thermal limit.
