NEMIX RAM DDR5 6400 CL52 128GB (2x64GB) ECC Registered RDIMM 2Rx4 1.1V ASRock Rack GNR2D16-2T memory upgrade

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.
