Exact-fit DDR5 ECC RDIMM for ASRock Rack servers

This 64GB kit contains two 32GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the ASRock Rack GNRD16DNO and GNRD16QM3-NL memory controllers expect. Registered ECC architecture and 1.1V operation match the board's DDR5 6400 specification so the full capacity is recognised at rated speed.

Registered ECC stability under sustained load

Registered buffering offloads the memory controller, allowing every populated slot to run at full capacity continuously. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long production workloads.

Verify DIMM population rules before ordering

Server memory support varies by model and BIOS revision. Consult the motherboard manual for approved capacities, slot population order and installation steps. This kit uses 288-pin RDIMM form factor and 1Rx4 organisation; UDIMM or SODIMM modules will not fit or function.
