NEMIX RAM
128GB DDR5 6400 registered ECC RDIMM with CL52 latency and 1.1V operation
This 128GB DDR5 module delivers 6400MHz speed with CL52 latency at 1.1V. It uses a 2Rx4 registered ECC design on a 288-pin RDIMM form factor. The memory is built for servers requiring PC5-51200 bandwidth and is not compatible with standard PC computers.
Registered buffering and ECC correction maintain data integrity during continuous operation. The 2Rx4 organisation supports high-density server configurations without signal degradation. Major OEM chips from Samsung, Micron or Hynix provide consistent throughput under prolonged load.
Operating at 1.1V reduces power draw compared to higher-voltage DDR5 variants. The registered design adds minimal overhead while stabilising the memory bus. Standard server airflow is sufficient for normal thermal management.

The module operates at the standard DDR5 voltage of 1.1 V, so power draw and heat output stay within the JEDEC baseline for 6400 MT/s registered DIMMs.
A server board with a 288-pin DDR5 RDIMM slot, registered-buffer support and ECC enabled in the BIOS is required; consumer desktop platforms cannot use this module.
Mixing ranks is possible if the platform’s memory controller supports mixed-rank populations; check the server vendor’s qualified-vendor list for approved combinations.
