Exact-match server kit

This 256 GB kit contains eight 32 GB DDR5 6400 RDIMMs rated at CL52 and 1.10 V. Each module is a 1Rx4 registered ECC part built with major OEM DRAM and uses the 288-pin form factor required by the target platform.

Verify motherboard rules

The ASRock Rack GNR2D16-2T motherboard dictates supported capacities, DIMM population order and installation steps. Consult the system or motherboard manual before ordering to confirm that eight registered DIMMs can be installed and will run at the rated 6400 MT/s speed.

Replaces mixed or smaller RDIMMs

Swapping out a partial population or lower-capacity registered ECC modules for this matched eight-module kit lets the memory controller run every slot at full rated speed with ECC protection. The jump is worth it when the workload needs the full 256 GB at DDR5 6400 without downclocking.

Questions about this item

Does the kit include all eight 32GB modules, or do I need to buy extra sticks to reach 256GB?

The package contains the full 256GB kit as eight matched 32GB DDR5 RDIMMs, so no additional modules are required for that capacity.

The listing shows a single 256GB 8x32GB kit — are there alternative capacities or speeds I should consider?

This specific part number MR51200-314K8 is offered only as an 8-module 256GB kit at DDR5 6400 CL52 1.1V; other capacities or speeds would carry different part numbers.

What does the DDR5 6400 CL52 rating mean once the kit is installed in the ASRock Rack GNR2D16-2T motherboard?

The modules will run at the rated 6400MT/s with CL52 timings at 1.1V, delivering the exact speed and latency the motherboard's memory controller expects for full-capacity operation.
