NEMIX RAM 256GB (8×32GB) DDR5 6400 CL52 ECC RDIMM for ASRock Rack W890D8-2L2T memory upgrade

Capacity and kit layout

This 256GB kit contains eight 32GB DDR5 ECC RDIMM modules for the ASRock Rack W890D8-2L2T motherboard. It is aimed at server and workstation builds that need registered memory with error correction. The kit delivers 256GB total capacity across all populated slots.

Build integration and slot use

Each module uses the 288-pin DDR5 RDIMM form factor and runs at 1.10V. Registered buffering reduces electrical load on the memory controller when all eight slots are filled. The kit occupies every DIMM socket on the board, so no further memory can be added without removing modules.

Headroom and limits

Rated at 6400MHz with CL52 latency, the memory operates at the platform's supported DDR5 speed. The 2Rx8 organisation provides density within each module. Builds requiring more than 256GB or lower latency than CL52 will need a different memory configuration.
