Exact-match server upgrade

This NEMIX RAM kit delivers 128GB of DDR5 memory in a two-module configuration built for the ASRock Rack GNR2D16-2T motherboard. Each 64GB module is a 288-pin registered DIMM with ECC and a 2Rx4 organisation. The kit operates at 6400 MT/s with CL52 latency at 1.1V, matching the board's qualified specifications exactly.

Sustained-load stability

Registered architecture buffers the address and command signals so the memory controller remains stable when all slots are populated at full capacity. ECC detects and corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. The 1.1V operating voltage keeps power draw consistent under continuous server duty cycles.

When the jump is worth it

This kit replaces smaller-capacity or slower DDR5 RDIMMs when the platform requires the full 128GB at 6400 MT/s with registered ECC. It is not for systems that accept only unbuffered UDIMMs, SODIMM form factors, or lower-density modules. Builders needing a different capacity, rank structure, or voltage should verify the motherboard's qualified-vendor list before purchasing.

Perguntas sobre este artigo

How much power does each 64 GB DDR5 6400 RDIMM draw at the rated 1.1 V?

Each module operates at 1.10 V; total kit capacity is 128 GB across two 64 GB RDIMMs, so power scales with the number of populated slots.

What motherboard and memory slots are required to install this 288-pin DDR5 RDIMM kit?

The kit is verified for the ASRock Rack GNR2D16-2T motherboard and requires DDR5 RDIMM slots; it will not fit UDIMM or SODIMM sockets.

Will the registered ECC design let me fill every DDR5 slot on the ASRock Rack board without downclocking?

Yes, the 2Rx4 registered architecture offloads the memory controller so all slots can run at the rated 6400 MT/s with ECC active.
