  • 32 GB capacity runs demanding server workloads at full speed
  • DDR5 6400 MHz rated frequency matches the ASRock Rack GNR2D16-2T memory controller
  • CL52 latency and 1.10 V operation meet exact JEDEC timing for stable registered performance
  • ECC and registered architecture correct single-bit errors while offloading the controller for full-slot population
  • 288-pin RDIMM form factor fits the board's DDR5 slots without adapters or mismatched modules

System-specific DDR5 RDIMM for ASRock Rack servers

This 32 GB registered ECC module is built to the exact electrical and mechanical requirements of the ASRock Rack GNR2D16-2T motherboard. It delivers DDR5 6400 speed with CL52 latency at 1.10 V in a 288-pin RDIMM form factor.

Registered DDR5 architecture limits

The registered buffer reduces electrical load on the memory controller, allowing every slot to be populated at full rated speed, while on-die ECC corrects single-bit errors before they affect data integrity. Your motherboard manual defines the supported capacities, approved population order and any slot-specific constraints that must be followed for stable operation.

Upgrade from lower-capacity or non-ECC DDR5 RDIMMs

Replacing smaller registered ECC modules with this 32 GB kit increases total memory bandwidth and capacity for virtualisation, database or compute workloads. The jump is worthwhile when your current configuration leaves slots empty or runs unbuffered memory that cannot scale to full population.

Questions about this item

Should I choose the 32GB DDR5-6400 CL52 1Rx4 module or a different capacity for the ASRock Rack GNR2D16-2T?

This kit provides a single 32GB registered ECC DDR5 DIMM at 6400MHz CL52. Consult the motherboard manual for supported total capacities and the required population order before adding more modules.

What does the 6400MHz rating deliver once the module is installed in the ASRock Rack GNR2D16-2T?

The module runs at DDR5-6400 (PC5-51200) with CL52 latency at 1.1V, giving the memory controller the exact speed and timing it expects for full-capacity operation in every populated slot.

How does the 288-pin RDIMM interface and registered ECC design affect real-world use?

The 288-pin registered DDR5 form factor offloads the memory controller, allowing full-speed operation with all slots populated, while on-die ECC corrects single-bit errors to prevent silent data corruption.
