System-specific DDR4 ECC module

This is a single 32GB DDR4 2400 ECC registered DIMM built for Supermicro SuperBlade servers. It runs at CL17 latency with 1.2V power draw and uses a 2Rx4 rank layout on a 288-pin VLP form factor. The module replaces several Supermicro part numbers and is validated for the listed blade models only.

Verify blade model and memory population rules

Confirm your chassis is one of the five SuperBlade models named in the compatibility list before ordering. The registered ECC design will not work in standard desktop boards and must not be mixed with unbuffered or load-reduced DIMMs. Check the system manual for maximum supported capacity per slot and any required population order across channels.

Suits operators upgrading listed SuperBlade units

This module fits technicians extending the life of the specified 6429 and 7128 SuperBlade servers with a validated 32GB upgrade. It is not for desktop builders, laptops, or any platform that requires unbuffered or non-ECC memory. Buyers needing different capacities, speeds, or form factors should look at other OWC system-specific kits.
