Exact-match 512 GB kit for Supermicro

This 512 GB kit contains four 128 GB DDR5 5600 RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDW-64C-SP9F memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly, so every slot runs fully populated at rated speed without silent data corruption. It is designed for administrators who need maximum registered ECC capacity on this specific platform.

Verify motherboard population rules before ordering

Consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Ensure the BIOS is current enough to recognise 4Rx4 modules at full 512 GB capacity and that your chassis airflow can cool fully populated banks.

Registered ECC RDIMMs with major OEM chips

Each module uses Samsung, Micron or Hynix components on a 288-pin RDIMM PCB without a heat spreader, relying on server-grade airflow for cooling. Registered buffering reduces electrical load on the memory controller, allowing all four slots to operate at 5600 MT/s and 1.1 V. ECC protection catches and corrects single-bit errors in real time, preventing unplanned reboots in production workloads.

Questions about this item

What comes in the 512GB kit and is any extra hardware needed for installation?

The kit contains four 128GB DDR5-5600 CL46 4Rx4 registered ECC RDIMMs. No additional parts are required; the modules plug directly into the 288-pin DIMM slots on the Supermicro X14SDW-64C-SP9F motherboard.

Should I choose a different capacity or speed grade for this motherboard?

This 512GB (4x128GB) kit matches the exact DDR5-5600 PC5-44800 4Rx4 registered ECC specification the X14SDW-64C-SP9F expects. Other capacities or speeds may not be recognised or could run at reduced rates.

Will the system actually run at 5600 MT/s with all four slots populated?

Yes. The registered 4Rx4 design offloads the memory controller so the board can run all four DIMMs at the rated 5600 MT/s (PC5-44800) with CL46 timing and 1.10V, provided the BIOS is configured for the validated population order.
