Exact-match server upgrade

This NEMIX RAM kit delivers 512 GB of DDR5-5600 registered ECC memory in four 128 GB modules built to the Supermicro X14SDW-40C-SP9F motherboard's exact specifications. The 288-pin RDIMM form factor, 4Rx4 rank structure, 1.1 V operating voltage and CL46 latency match the board's memory-controller expectations so the full capacity is recognised at rated speed.

Registered ECC architecture

Registered buffering offloads the memory controller, allowing every slot to run fully populated at 5600 MT/s while on-die ECC corrects single-bit errors before they cause data corruption or unplanned reboots. The kit contains only the four RDIMMs; no heat spreaders, cables or software are included.

For maximising X14SDW-40C-SP9F capacity

Administrators populating all available DIMM slots on this specific Supermicro board with validated DDR5-5600 registered ECC modules will achieve the full 512 GB. Builders needing unbuffered UDIMMs, SODIMMs, lower capacities, different speeds or non-ECC memory should look elsewhere.
