  • 2Rx4 organisation enables full population without memory-controller overload

Server Memory Kit

This 512GB kit contains eight 64GB DDR5 RDIMM modules rated at 6400MT/s with CL52 latency and 1.1V operation. It is built for ASRock Rack GNRD16DNO and GNRD16QM3-NL motherboards that require registered ECC memory. The 2Rx4 organisation and exact voltage match the platform's memory controller expectations.

Registered ECC Limits

Registered buffering reduces electrical load on the memory controller so all eight slots can run populated at the rated 6400MT/s speed. ECC corrects single-bit errors automatically to prevent silent data corruption. The DDR5 288-pin RDIMM form factor is physically and electrically incompatible with UDIMM or SODIMM slots.

Pre-Purchase Checks

Confirm your motherboard manual lists 64GB 2Rx4 RDIMMs in an eight-module population at DDR5 6400. Verify the approved DIMM installation order for full 512GB capacity. Ensure the system BIOS is updated to a version that supports this density and speed combination before installation.

Questions about this item

Should I pick the 512GB kit with eight 64GB modules or a different capacity for my ASRock Rack GNRD16DNO?

This kit provides 512GB total using eight 64GB RDIMMs, matching the exact population the board expects for full-capacity operation at DDR5-6400.

What does the DDR5-6400 rating mean when the memory is installed in a GNRD16QM3-NL?

The modules run at 6400 MT/s with CL52 latency at 1.10V, delivering the PC5-51200 bandwidth the motherboard's memory controller is designed for.

How does the 288-pin registered ECC interface affect real-world stability?

Registered buffering reduces electrical load on the controller so all eight slots stay stable at full speed, while ECC corrects single-bit errors on the fly.
