NEMIX RAM 256GB (4x64GB) DDR5 6400 CL52 4Rx4 ECC RDIMM Supermicro X14SDW-36C-SP9F memory upgrade

Exact-Match DDR5 Upgrade

This 256 GB kit contains four 64 GB DDR5 6400 RDIMMs built to the precise rank, voltage, and timing the Supermicro X14SDW-36C-SP9F expects. Registered ECC modules let the board recognise the full capacity and run at the rated speed without manual tuning. It is intended for administrators who need guaranteed compatibility in that specific platform.

Capacity and Headroom

Four 4Rx4 modules fill four slots at 1.1 V and CL52, delivering 256 GB of registered ECC memory for virtualisation, databases, or large datasets. The buffered architecture keeps every slot stable when fully populated, while ECC corrects single-bit errors before they affect production workloads. Systems requiring more than four DIMMs or higher frequencies will exceed what this kit provides.

Replaces Smaller RDIMM Sets

The kit replaces lower-capacity DDR5 RDIMM kits or mixed-rank configurations that limit total memory or prevent full-speed operation. The upgrade is worthwhile when the workload demands the full 256 GB at DDR5 6400 and the board's population rules call for four 4Rx4 registered modules. Boards that only accept UDIMMs or SODIMMs cannot use this memory.
