768GB DDR5 ECC RDIMM kit for ASUS S14NA-U12

This 768GB kit contains six 128GB DDR5 4800 ECC registered DIMMs built for the ASUS S14NA-U12 server board. It targets administrators expanding memory capacity in compatible enterprise systems.

4Rx4 quad-rank organisation

Each module uses a 4Rx4 layout with CL40 latency at 1.1V. The quad-rank density decides whether the board’s memory controller can address the full 768GB across all twelve slots.

Standard 288-pin DDR5 installation

Modules insert vertically into the board’s 288-pin DDR5 slots without tools. The most common issue is populating slots in the wrong sequence, which prevents the system from recognising the full capacity.

Highlights

  • 768 GB total capacity for large-scale workloads
  • DDR5 4800 speed with PC5-38400 bandwidth
  • ECC registered design protects data integrity
  • 1 V operation reduces power draw

Questions about this item

What does 4800 MT/s mean once the modules are installed in the ASUS S14NA-U12?

The kit runs at DDR5 4800 (PC5 38400) with CL40 latency, delivering the rated speed when populated in supported slots on the ASUS S14NA-U12 board.

How does the ECC RDIMM interface affect usable bandwidth?

Registered ECC RDIMMs add a clock cycle for command buffering and provide error correction, so sustained throughput is slightly below the raw 38400 MB/s rating but gains data integrity.

Will the 288-pin DDR5 RDIMM modules fit the server board without clearance issues?

Yes, the 288-pin DDR5 RDIMM form factor matches the ASUS S14NA-U12 memory slots; the modules have no heat spreader, keeping height to the standard RDIMM profile.
