Targeted Server Memory Upgrade

This 128GB DDR5 RDIMM module is built for the Supermicro X14SDW-72C-SP9F motherboard. It delivers registered ECC operation at 5600MHz with a CL46 latency and 1.1V requirement. The 4Rx4 organisation matches the board's memory controller expectations exactly. It suits administrators who need maximum capacity per slot in a validated configuration.

Build Integration Requirements

The 288-pin registered form factor fits only DDR5 RDIMM slots; it will not work in UDIMM or SODIMM sockets. Because the module is registered, it reduces electrical load on the memory controller, allowing full population of available slots. ECC functionality requires a platform that supports error-correcting code operation. No heat spreader is included, so chassis airflow must handle thermal management.

Included Module Benefits

The single 128GB kit provides an exact-match upgrade using major OEM DRAM components. Registered architecture enables stable operation when all supported slots are filled. ECC corrects single-bit errors automatically, protecting data integrity in production workloads. The package contains only the memory module itself; no additional cables, software licences or mounting hardware are supplied.

Questions about this item

How much power does each module draw at 1.10V under continuous load?

Each module operates at 1.10V, the standard DDR5 RDIMM voltage, so power draw scales with the 5600 MT/s data rate and 4Rx4 density rather than exceeding the platform's registered DIMM budget.

Will the lack of a heat spreader raise temperatures in a fully populated Supermicro X14SDW-72C-SP9F chassis?

The modules ship without a heat spreader; registered ECC DDR5 at 5600 MT/s relies on the server's directed airflow across the 288-pin slots to keep DRAM temperatures within spec.

Does my Supermicro X14SDW-72C-SP9F need a specific BIOS revision to recognise 128GB 4Rx4 RDIMMs?

The board's memory-population rules determine supported capacities and slot order; consult the motherboard manual for the required BIOS version and approved DIMM configuration before installing.
