  • 1 V operation matches the server memory controller specification
  • 288-pin RDIMM form factor fits ASRock Rack GNRD16DNO and GNRD16QM3-NL

Targeted server upgrade

This 512GB kit delivers four 128GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built for administrators expanding ASRock Rack GNRD16DNO or GNRD16QM3-NL systems that require registered ECC memory in a 288-pin form factor.

Thermals and power

Each module runs at the standard DDR5 voltage of 1.10V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep power draw predictable when all slots are populated.

Build integration

The 2Rx4 registered ECC design matches the motherboard's population rules so the system recognises the full capacity at rated speed. Buyers needing unbuffered UDIMMs, SODIMMs, or non-ECC modules should look elsewhere, as this kit fits only RDIMM slots with registered support.

Questions sur cet article

How do I install the four 288-pin RDIMMs in the ASRock Rack GNRD16DNO, and which slot order do people often get wrong?

Populate all four slots in the exact sequence listed in the motherboard manual; the board requires a specific DIMM population order for full 512 GB recognition at DDR5 6400.

What maintenance or replacement will the 2Rx4 registered ECC modules need over time?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and the modules are covered by a lifetime replacement warranty if a fault ever develops.

What limit appears first when the kit runs at 6400 MT/s continuously under full load?

The memory controller's maximum supported speed of DDR5 6400 (PC5-51200) is the first ceiling; the modules operate at 1.1 V and CL52 within that rated envelope.
