Exact-fit DDR5 ECC RDIMM kit

This 384GB kit delivers four 96GB DDR5 6400 modules built to the precise rank, voltage and timing the server memory controller expects so the system recognises full capacity and runs at rated speed. It targets administrators upgrading ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboards where registered ECC memory is required.

Registered architecture for full population

The 288-pin RDIMM form factor matches the board's memory population rules and the registered design offloads the memory controller allowing every slot to run fully populated at full capacity. No heat spreader is fitted so clearance matches the motherboard's standard DIMM spacing without extra height.

Sustained error correction under load

ECC catches and corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots during continuous operation. The 1.10V operating voltage and CL52 latency remain stable across extended workloads while the 2Rx4 organisation maintains signal integrity at the rated DDR5 6400 speed.

Questions about this item

How many DIMM slots does the 384GB kit fill on the ASRock Rack GNRD16DNO motherboard?

The kit contains four 96GB modules, occupying four 288-pin DDR5 RDIMM slots on the ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboard.

Does the registered ECC design keep thermals and power draw stable during continuous 24/7 server workloads?

Registered buffering reduces electrical load on the memory controller, while 1.10V operation and ECC error correction maintain stable thermals and power draw during sustained use.

Must the motherboard BIOS already support DDR5-6400 PC5-51200 2Rx4 registered ECC before installing this kit?

Yes, the ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboard must support DDR5-6400 PC5-51200 2Rx4 registered ECC DIMMs for the kit to be recognised at full capacity and rated speed.
