512GB DDR5 ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR5 6400 modules with CL52 latency, 1.1V operation and 2Rx4 registered ECC architecture. It is built for servers that require registered DIMMs and error-correcting memory at full population.

Suited for ASRock Rack GNR2D16-2T

The kit matches the motherboard's DDR5 6400 registered DIMM requirements and population rules. It is not for systems that accept only unbuffered UDIMMs, SODIMMs or non-ECC memory, nor for boards limited to lower capacities or slower speeds.

Eight Slots Fully Populated

Eight 64GB modules fill every slot on the supported board, delivering 512GB at the rated 6400 transfer rate with registered buffering and ECC active. Headroom ends when the platform's maximum DIMM count or total capacity is reached, or if a workload demands speeds beyond DDR5 6400.

Highlights

  • 512 GB total capacity from eight 64 GB modules
  • DDR5-6400 speed with CL52 latency at 1.10 V
  • Registered ECC design corrects single-bit errors automatically
  • 2Rx4 rank layout matches ASRock Rack GNR2D16-2T requirements
  • 288-pin RDIMM form factor fits server memory slots

Questions about this item

What motherboard must I already have for this 512GB DDR5 6400 CL52 ECC RDIMM kit to work?

The kit is verified for the ASRock Rack GNR2D16-2T motherboard that requires 288-pin registered DDR5 DIMMs at 1.1V.

How will these 2Rx4 registered ECC modules behave if I keep older DDR5 RDIMMs in the same server?

Mixing ranks or speeds can prevent the board from running at 6400 MT/s; populate all eight slots with this matched kit for full 512GB capacity and rated performance.

How can I confirm the kit is running at DDR5 6400 with CL52 after installation?

Check the BIOS memory information or OS tools such as dmidecode to see 6400 MT/s, CL52, 1.1V and ECC active across all 512GB.
