Exact-match DDR5 server kit

This 384GB kit contains twelve 32GB DDR5 6400 RDIMMs built to the precise rank, voltage and timing the ASRock Rack GNRAPD12DNO motherboard expects. Each module is a 288-pin registered ECC DIMM rated at 1.10V with CL52 latency, so the memory controller recognises the full capacity at rated speed.

Registered ECC architecture

The registered design offloads the memory controller, allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly. This combination stops silent data corruption and unplanned reboots before they reach production workloads.

1Rx4 organisation decides fit

The 1Rx4 rank structure must match the motherboard's qualified vendor list; boards that require a different rank per DIMM will not support this kit at the rated 6400 MT/s. Consult the system manual for approved population rules before purchase.

Questions about this item

How long will the 12 registered DIMMs last before a chip or solder joint fails?

The modules carry a lifetime replacement warranty and are built with major OEM Samsung, Micron or Hynix components; individual DIMMs can be swapped without replacing the full 384 GB kit.

What limit appears first when all 12 slots run DDR5-6400 CL52 continuously?

The memory controller on the ASRock Rack GNRAPD12DNO board reaches its maximum supported population and speed before any module timing or voltage threshold is exceeded.

How much heat and power does the 1.1 V kit produce under all-day load?

At 1.10 V with no heat spreaders, each 32 GB RDIMM draws minimal power and relies on chassis airflow; registered buffering reduces electrical load on the controller during sustained operation.
