1 TB DDR5 RDIMM kit for ASRock Rack servers

This 1 TB kit contains eight 128 GB DDR5 registered ECC modules rated at 6400 MT/s with CL52 latency at 1.1 V. It is built for the ASRock Rack GENOA2D16NQM3-2Q motherboard where full population of 288-pin RDIMM slots is required for maximum capacity.

Replaces partial or mismatched DDR5 populations

Servers running with fewer than eight modules or mixed ranks will not reach the board's full 1 TB limit. The jump is worth it when workloads need every slot filled with 2Rx4 registered DIMMs so the memory controller sees a uniform, validated configuration at rated speed.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous full-population operation, while on-die ECC corrects single-bit errors in real time. This combination keeps throughput stable and prevents silent data corruption during extended compute or database tasks.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the memory slots on my ASRock Rack GENOA2D16NQM3-2Q motherboard?

Yes, the 288-pin Registered RDIMM form factor matches the slots required by the GENOA2D16NQM3-2Q, and the kit is verified for that board.

What is the correct population order for the eight 128GB modules on this board?

Consult the ASRock Rack motherboard manual for the approved DIMM population sequence; installing modules in the wrong slots will prevent the system from recognising the full 1TB capacity.

Do these ECC RDIMMs require any firmware updates or periodic maintenance after installation?

No firmware updates are needed for the memory itself; ECC error correction operates automatically, and the modules have no heat spreaders or moving parts that require servicing.
