Capacity and form factor

This is a 1TB DDR5 server memory kit containing eight 128GB registered ECC RDIMMs. It is built for administrators upgrading ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboards that require 288-pin registered modules.

Speed and timing

The kit runs at DDR5 6400 (PC5-51200) with a CAS latency of CL52 at 1.1V. The 2Rx4 rank structure matches the memory controller expectations on the target boards so the full capacity is recognised at rated speed.

Registered ECC architecture

Registered buffering reduces electrical load on the memory controller, allowing all slots to be populated at maximum capacity. On-board ECC corrects single-bit errors in flight, protecting data integrity in production workloads. This kit will not fit systems that require unbuffered UDIMMs or SODIMMs.

Questions about this item

Will the DDR5 6400 speed run at its full 6400 MT/s rate once installed in an ASRock Rack GNRD16DNO?

Yes, the kit is validated for that motherboard so the memory controller will initialise all eight modules at the rated DDR5 6400 speed without down-clocking.

Does the PC5-51200 designation limit the usable bandwidth on this platform?

PC5-51200 is the peak transfer rate that matches DDR5 6400; the registered DIMM interface lets the board sustain that bandwidth across all populated slots.

What physical slot and clearance requirements do these 288-pin RDIMMs need?

They require standard 288-pin DDR5 RDIMM sockets and have no heat spreader, so they fit in tight server chassis without extra height clearance.
