NEMIX RAM RS700A-E12-RS4U 1TB (8x128GB) DDR5 4800 CL40 ECC RDIMM memory upgrade

1 TB DDR5 4800 ECC RDIMM kit

This eight-module kit delivers 1 TB of registered DDR5 memory at 4800 MT/s with CL40 latency. It is built for the ASUS RS700A-E12-RS4U dual-processor 1U server and operates at 1.1 V. The 4Rx4 organisation and on-die ECC suit workloads that require data integrity and high capacity per slot.

Sustained load behaviour

Registered buffering and ECC correction maintain signal quality across all twelve channels during continuous operation. The 1.1 V operating voltage limits thermal output inside the dense 1U chassis. Modules use major OEM Samsung, Micron or Hynix chips that are stress-tested under load before shipment.

DDR5 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s per pin, so bandwidth scales with populated channels rather than higher clock speeds. Four-rank 4Rx4 modules place greater electrical load on the memory controller, restricting maximum DIMMs per channel compared to dual-rank alternatives. No heat spreaders are fitted, so chassis airflow must handle module cooling.
