Exact-match DDR5 ECC RDIMM kit

This 128GB kit comprises four 32GB DDR5 6400 modules built to the 288-pin Registered ECC form factor. It targets administrators upgrading a Supermicro X14SDW-64CM-SP9F motherboard that requires registered DIMMs with 2Rx4 organisation and 1.10V operation.

Capacity headroom and limits

The four-module population delivers 128GB of registered ECC capacity, allowing every slot to run fully populated at the rated 6400MT/s speed. Systems needing more than 128GB or a different rank configuration will not be served by this kit.

Thermals and power in normal use

Operating at 1.10V with CL52 timings, the modules draw minimal power and run without heat spreaders in typical server airflow. Registered buffering reduces electrical load on the memory controller, keeping thermals stable during sustained workloads.

Questions about this item

Will the 1.10V DDR5 6400 2Rx4 modules work with the existing DIMMs in my Supermicro X14SDW-64CM-SP9F?

The kit is spec-matched to the X14SDW-64CM-SP9F memory population rules. Mixing with existing DIMMs requires identical speed, voltage, rank, and ECC type; otherwise the system may downclock or fail to boot. Check the manual for approved population order.

How do I verify the 128GB DDR5 6400 CL52 kit is running at its rated speed after installation?

Enter the BIOS and confirm the memory reports DDR5 6400 (PC5-51200) with CL52 timings at 1.10V across all four slots. The registered ECC design ensures the controller recognises the full 128GB capacity when populated per the board's guide.

Does the 4x32GB NEMIX RAM kit include a heat spreader, or do I need to buy cooling separately?

The modules ship without a heat spreader. The 288-pin RDIMMs rely on standard server chassis airflow for cooling; no additional cooling accessory is included or required for typical rackmount operation.
