NEMIX RAM 64GB (4x16GB) DDR5 6400MHz CL52 ECC RDIMM for ASRock Rack W890D8-2L2T

Server-grade DDR5 ECC kit

This 64 GB kit contains four 16 GB registered DIMMs built for the ASRock Rack W890D8-2L2T motherboard. Each module runs at 6400 MHz with a CAS latency of 52 at 1.10 V. The registered design adds a buffer that stabilises heavy multi-module loads in enterprise environments.

RDIMM capacity ceiling

Registered DIMMs let the memory controller address more ranks per channel than unbuffered modules, so larger kits remain stable. The four-module population fills every slot on the target board, leaving no room for further expansion without replacing the entire kit. Buyers who want more storage must choose a different platform.

Bare-module practicality

Without heat spreaders the modules sit at standard height, fitting tight server chassis and multi-GPU workstation builds. Gold-plated 288-pin edges resist oxidation during long uptime cycles. The 1Rx8 organisation keeps electrical loading low per rank, helping signal integrity when all four slots are populated.
