128GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB across two 64GB DDR5 modules rated at 5600MHz with CL46 latency. It is built for servers and workstations that require registered ECC memory for data integrity. The modules operate at 1.1V and use a 288-pin RDIMM form factor.

Fits ASRock Rack TURIND8X-2T/500W motherboards

The kit is validated for the ASRock Rack TURIND8X-2T/500W platform and installs directly into its DDR5 RDIMM slots. Registered buffering reduces electrical load on the memory controller, freeing headroom for dense configurations. No heat spreader is fitted, so airflow across the modules must be provided by the chassis.

Suited for ECC-capable server builds

This memory suits administrators upgrading the named ASRock Rack board or compatible systems needing 128GB of registered ECC DDR5. Builders requiring unbuffered UDIMMs, non-ECC modules, lower capacities, or different speeds should look elsewhere. The 2Rx4 organisation also demands a platform that supports this rank configuration.
