NEMIX RAM 384GB 12x32GB DDR5 4800 CL40 1Rx4 1.1V 288-pin ECC RDIMM kit for ASRock Rack GENOA2D24G-2L+

Exact-fit server memory kit

This 384GB kit contains twelve 32GB DDR5 registered ECC RDIMMs built to the precise rank, voltage and timing the ASRock Rack GENOA2D24G-2L+ memory controller expects. It installs as a matched set so the board recognises full capacity at the rated 4800MT/s speed without manual tuning. Builders who need unbuffered UDIMMs or laptop SODIMMs cannot use these modules.

Thermals and power in normal use

Each module operates at 1.1V without a heat spreader, relying on chassis airflow to keep temperatures low during typical server workloads. The registered architecture buffers address and command signals, reducing electrical load on the memory controller and helping the system run quietly under standard utilisation. No active cooling is included on the DIMMs themselves.

Behaviour under sustained load

ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption during long-running compute or database tasks. Fully populating all slots with 1Rx4 registered modules maintains stability at the rated CL40 latency because the buffer offloads the controller even at maximum population. Buyers who require higher frequencies or lower latencies than DDR5-4800 CL40 should verify motherboard support before purchasing.
