Server Memory Kit Overview

This NEMIX RAM kit delivers 768GB total capacity across six 128GB DDR5 RDIMM modules. It operates at 5600MHz with CL46 latency and 1.1V voltage, using registered ECC architecture for error correction. The modules are validated specifically for the ASRock Rack TURIND12M3-2Q/500W motherboard.

Target Server Builders

Suited for administrators upgrading that specific ASRock Rack board to its maximum supported capacity with a matched kit. The registered design and ECC function are required for stable operation under full population. Builders using consumer motherboards, workstations needing unbuffered UDIMMs, or systems limited to lower densities should look at other memory types.

Registered ECC Architecture

The RDIMM registered buffer reduces electrical load on the memory controller, allowing all six slots to run at the rated 5600MHz speed. ECC corrects single-bit errors automatically, preventing silent data corruption. This combination of registration and error correction is the specification that determines compatibility with the target server platform.

Questions about this item

Does the 1.1V DDR5-5600 2Rx4 registered ECC kit run cool and quiet when the server is fully populated 24/7?

The modules operate at 1.1V with no heat spreader, relying on the server's forced airflow; registered buffering reduces electrical load on the memory controller so all six slots can stay populated at rated speed continuously.

What must the motherboard already provide for this 768 GB kit to be recognised at full capacity and speed?

The ASRock Rack TURIND12M3-2Q/500W motherboard must support DDR5-5600 RDIMMs, 2Rx4 organisation, registered ECC operation and a six-DIMM population rule that allows 128 GB per slot.

Will the CL46 2Rx4 registered ECC modules work alongside older DDR5 RDIMMs I might keep in the same chassis?

Mixing ranks, voltages or timings is not supported; the board's memory controller expects identical 1.1V CL46 2Rx4 registered ECC modules in every populated slot to run at DDR5-5600 without down-clocking or errors.
