NEMIX RAM 768GB (6x128GB) DDR5 4800 CL40 ECC RDIMM SuperMicro X13SET-G X13SET-GC memory upgrade

SuperMicro X13SET-G 768GB DDR5 kit

This 768GB kit contains six 128GB DDR5 4800 registered ECC RDIMMs validated for SuperMicro X13SET-G and X13SET-GC motherboards. It targets administrators who need maximum registered memory capacity in a single server or workstation platform. The modules operate at 1.1V with CL40 latency and a 4Rx4 organization. Each stick uses major OEM Samsung, Micron or Hynix components under part number MR38400-744K6.

Sustained server workload behavior

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded database, virtualization or scientific compute loads. The 4Rx4 rank structure allows the memory controller to interleave requests across all six modules without exceeding electrical loading limits. DDR5 4800 bandwidth at PC5-38400 feeds many cores simultaneously rather than relying on short burst speeds. Stability is verified through extended stress testing before shipment.

Thermals noise and power draw

Bare modules without heat spreaders rely on chassis airflow directed across the 288-pin RDIMM slots. Operating at 1.1V keeps per-module power low even when all 768GB are populated, reducing the cooling burden in dense 1U or 2U enclosures. No active cooling components are present, so acoustic output depends entirely on system fan curves. The low voltage also limits cumulative power draw across the full kit.
