  • 288-pin RDIMM form factor fits the ASRock Rack GENOA2D16NQM3-2Q DIMM slots precisely

Exact-match server upgrade

This 256GB kit delivers four 64GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10V operation. Registered ECC architecture and 2Rx4 organisation match the ASRock Rack GENOA2D16NQM3-2Q memory controller requirements for full-capacity recognition at rated speed.

Build integration and capacity

The 288-pin RDIMM form factor fits only motherboards designed for registered DDR5 modules; UDIMM or SODIMM slots will not accept these sticks. Registered buffering offloads the memory controller so every slot can be populated at full density, while ECC corrects single-bit errors before they reach production workloads.

Sustained-load behaviour

Registered signalling and on-die ECC maintain signal integrity and data correctness across all four modules during continuous multi-threaded server tasks. The 1.10V operating point keeps power draw predictable under prolonged utilisation, and the CL52 timing remains stable without relying on short-burst headroom.

Questions sur cet article

Will the 1.1V operating voltage limit how many DIMMs I can populate on this board?

The kit runs at 1.1V, matching the DDR5 RDIMM standard the ASRock Rack GENOA2D16NQM3-2Q expects, so all four slots can be filled without exceeding the platform's voltage budget.

How much heat and noise should I expect from four 64GB RDIMMs running 24/7?

The modules have no heat spreader and draw 1.1V at DDR5-6400; they rely on chassis airflow, so sustained load stays quiet as long as your server fans maintain normal flow across the DIMM slots.

Does my motherboard need a specific BIOS revision or CPU stepping to recognise 256GB of 2Rx4 DDR5-6400?

The kit is validated for the ASRock Rack GENOA2D16NQM3-2Q; consult that board's manual for the exact population order and any firmware version required before installing all four 64GB RDIMMs.
