Exact-match server upgrade

This 768 GB kit contains eight 96 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for the ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards that require registered ECC modules in a 288-pin form factor.

Registered ECC stability

Each module uses a 2Rx4 organisation and registered buffering to reduce electrical load on the memory controller when all slots are populated. ECC circuitry detects and corrects single-bit errors on the fly, helping prevent silent data corruption in production workloads.

Verify population rules first

Consult your motherboard manual for the approved DIMM installation order and maximum supported capacity per channel before ordering. This kit will not fit systems that require UDIMM, SODIMM or non-ECC memory.

Questions about this item

What DDR5 speed and data rate does this kit run at?

The kit is rated for DDR5-6400, which corresponds to a PC5-51200 data rate.

What physical slot and form factor do these modules require?

Each module uses a 288-pin RDIMM form factor and must be installed in a 288-pin DDR5 RDIMM slot on the motherboard.

What is the correct population order for all eight modules?

Install the DIMMs following the exact slot sequence shown in the ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboard manual; skipping or reversing slots prevents the system from recognising the full 768 GB.
