768GB DDR5 ECC RDIMM kit

This 768GB kit contains twelve 64GB DDR5 4800 registered ECC modules built for the ASUS S14NA-U12 server board. It targets administrators who need maximum memory capacity for virtualization, databases or high-performance computing workloads. The registered design and error-correcting code protect data integrity in mission-critical environments.

Registered ECC with 2Rx4 organisation

Each module uses a 2Rx4 configuration and operates at 1.1V with CL40 latency at the DDR5 4800 (PC5-38400) data rate. The registered buffer reduces electrical load on the memory controller, allowing all twelve DIMMs to run simultaneously without signal degradation. ECC detects and corrects single-bit errors to maintain system stability under sustained load.

288-pin RDIMM form factor, no heat spreader

The bare 288-pin modules fit standard DDR5 RDIMM slots and rely on server chassis airflow for cooling. Absence of a heat spreader keeps the stack height low, easing installation in dense 1U or 2U enclosures where adjacent DIMM slots are tightly spaced. Compatibility is validated specifically for the ASUS S14NA-U12 platform.

Questions about this item

Will the 12 modules in this 768GB kit ever need replacement under normal server operation?

Registered ECC DDR5 modules have no moving parts and are rated for continuous duty; replacement is only needed if a module fails validation or a capacity upgrade is required.

What limit appears first when all 12 DIMMs run at DDR5 4800 CL40 under sustained load?

The memory controller’s maximum supported rank count per channel is reached before bandwidth or thermal limits become a factor.

How much heat and power does the 1.1V registered kit produce when the server runs all day?

Each 64GB 2Rx4 RDIMM operates at 1.1V without a heat spreader, so total power draw scales with the 12-module population and airflow handles the resulting heat.
