Exact-match server upgrade

This 32 GB DDR5 registered ECC RDIMM runs at 6400 MHz with CL52 latency and 1.1 V. It is built for the ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards, delivering the precise rank, voltage and timing the memory controller expects.

No extra accessories included

The package contains only the single 288-pin module. There are no heat spreaders, cables or software utilities supplied, so the component relies entirely on the server chassis airflow and the board native memory management.

Verify DIMM population rules

Check the motherboard manual for supported capacities per slot, approved population order and maximum total memory before ordering. This module is not compatible with systems that require unbuffered UDIMMs or SODIMM form factors.

Questions about this item

Will the 1Rx4 ECC RDIMM need any firmware updates or component swaps over its service life?

The module uses major OEM Samsung, Micron or Hynix DRAM with on-die ECC and a registered buffer; no user-serviceable parts or firmware updates are required after installation.

What electrical or thermal limit appears first when the DIMM runs continuously at DDR5 6400 CL52?

The JEDEC 1.10 V operating voltage and CL52 latency set the power envelope; sustained loads stay within the DDR5 6400 specification without triggering thermal throttling.

How much noise and heat does the bare 288-pin RDIMM produce in a fully populated server chassis all day?

With no heat spreader the module relies on chassis airflow; it adds no fan noise and its 1.10 V DDR5 6400 rating keeps incremental heat low in a properly ventilated rack.
