NEMIX RAM 128GB (2x64GB) DDR5 5600 CL46 1.1V ECC Registered RDIMM memory upgrade

Server-grade DDR5 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 5600 registered ECC RDIMMs built for the GIGABYTE MZ23-SU0 motherboard. The modules run at 1.1V with CL46 latency and a 2Rx4 rank layout that matches the board's memory controller expectations. Registered buffering offloads the controller so every populated slot operates at full rated speed. It targets administrators who need maximum capacity with error correction for production workloads.

Verify motherboard population rules

Consult the GIGABYTE MZ23-SU0 manual for supported capacities, approved DIMM population order and installation steps before ordering. The board requires 288-pin RDIMMs; UDIMM or SODIMM modules will not fit or function. Confirm the system BIOS revision supports the full 128GB configuration across both slots. Buyers who need a different form factor or non-ECC memory cannot use this kit.

Thermals noise and power draw

The modules operate at the standard DDR5 1.1V with no heat spreader, relying on chassis airflow for cooling. Registered ECC RDIMMs draw slightly more power than unbuffered equivalents due to the register circuitry, but remain within normal DDR5 limits. No active cooling components are present, so acoustic output is zero; only system fans contribute noise. Buyers seeking lower-voltage or lower-capacity alternatives should look elsewhere.
