  • Validated for ASUS S14NA-U12 server boards

Capacity and Compatibility

This 64 GB DDR5 module is built for ASUS server boards such as the S14NA-U12. It delivers registered ECC operation at 4800 MT/s with a CL40 latency and runs at the standard 1.10 V. The 2Rx4 organisation and 288-pin RDIMM form factor suit enterprise workloads that require error correction and signal buffering.

Sustained Load Behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous throughput. The module uses major OEM chips from Samsung, Micron or Hynix and has been stress tested under load. The absence of a heat spreader means airflow across the DIMM slots must be adequate for prolonged high utilisation.

DDR5 Interface Limits

The PC5-38400 rating defines the peak transfer ceiling for this speed grade. Single-rank expansion beyond this module would require additional DIMM slots and motherboard support for the registered command protocol. Systems not designed for DDR5 RDIMM memory cannot accept this module.

Questions about this item

How much heat and power does this 1.1 V DDR5 4800 module generate under continuous load?

It runs at the standard DDR5 voltage of 1.1 V, which keeps power draw and heat output lower than earlier DDR generations while sustaining 4800 MT/s throughput.

What motherboard slot and chipset support are required to install this 288-pin RDIMM?

You need a server board with 288-pin DDR5 RDIMM slots and a chipset that supports registered ECC memory, such as the ASUS S14NA-U12 referenced in the compatibility list.

Can this 2Rx4 CL40 registered module share channels with other DDR5 RDIMMs of different rank or latency?

Yes, provided the motherboard's memory controller supports mixed-rank DDR5 populations; the module follows JEDEC DDR5 RDIMM specs so it will negotiate the lowest common speed and latency across populated channels.
