What this module is and who it fits

This 128GB DDR5 6400MHz PC5-51200 2Rx4 CL52 1.1V ECC Registered RDIMM is built for the ASRock Rack GENOA2D16NQM3-2Q motherboard. The 288-pin registered form factor and exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at rated speed.

What to confirm before ordering

Check your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. Server and motherboard memory support varies by model, so verify the exact configuration this board requires before purchase.

Behaviour under sustained load

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity. ECC catches and corrects single-bit errors on the fly, stopping silent data corruption and unplanned reboots before they reach production.

Questions about this item

Does the 128GB DDR5 6400MHz RDIMM ship as a single module or a multi-stick kit?

The package contains one 128GB 288-pin DDR5 RDIMM rated at 6400MHz PC5-51200 with CL52 latency, 1.10V operation and 2Rx4 registered ECC. No additional modules, cables or brackets are included.

I see only one capacity listed; is this 128GB module the only option for the ASRock Rack GENOA2D16NQM3-2Q?

This listing offers the single 128GB DDR5 6400MHz 2Rx4 CL52 1.10V registered ECC RDIMM. Other capacities or speeds are not shown here, so confirm your board's qualified-vendor list before ordering a different size.

Will the CL52 timing at 6400MHz run at that speed automatically on the GENOA2D16NQM3-2Q?

The module is spec-matched to the motherboard's DDR5 6400MHz PC5-51200 requirement, so the memory controller should recognise the 2Rx4 registered ECC DIMM at its rated 6400MHz CL52 1.10V without manual tuning.
