NEMIX RAM 768GB 12x64GB DDR5 6400 CL52 2Rx4 RDIMM Kit ASRock Rack GNRAP2D24G-2L+

768GB DDR5-6400 RDIMM Kit

This 768GB kit contains twelve 64GB DDR5-6400 Registered ECC RDIMMs built for the ASRock Rack GNRAP2D24G-2L+ motherboard. The modules run at 1.1V with CL52 latency and a 2Rx4 rank structure that matches the board's memory controller requirements. It is intended for administrators who need the full 768GB capacity recognised at rated speed without manual tuning.

Registered ECC Stability

The registered architecture buffers address and command signals so all twelve slots can remain fully populated at DDR5-6400 without overloading the memory controller. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during sustained workloads. This combination keeps throughput consistent across long-running server tasks.

2Rx4 Rank Configuration

Each DIMM uses a 2Rx4 organisation, a detail the memory controller expects for correct population and full-capacity operation. Using modules with a different rank layout would prevent the system from recognising the full 768GB or running at the rated 6400 MT/s. Buyers who need a different rank structure or a lower total capacity should select another kit.
