NEMIX RAM 64GB (2x32GB) DDR5 6400MHz CL52 2Rx8 ECC RDIMM ASRock Rack W890D8-2L2T memory upgrade

64GB DDR5 ECC RDIMM kit for ASRock Rack W890D8-2L2T

This 64GB kit contains two 32GB registered DDR5 modules built for the ASRock Rack W890D8-2L2T motherboard. Each module runs at 6400MHz with a CAS latency of CL52 and operates at 1.1V. The ECC RDIMM design targets servers and workstations that require error correction and signal integrity.

288-pin DDR5 installation with registered buffering

The 288-pin DDR5 RDIMMs install into the board's standard memory slots in minutes. Registered buffering adds a clock cycle, so the memory controller must support registered DIMMs; otherwise the system will not post. No heat spreader is fitted, so airflow across the modules must be adequate for sustained server workloads.

64GB capacity with 2Rx8 organisation

The 64GB total capacity handles virtualisation, database caching and large dataset processing comfortably. Dual-rank 2Rx8 organisation increases density per channel but can limit maximum populated speed on some platforms. Workloads exceeding 64GB or requiring higher frequencies than 6400MHz will need a larger or faster kit.
