Exact-match server upgrade

This NEMIX RAM module provides 128GB of DDR5 registered ECC memory rated at 5600MHz with CL46 latency. It is built for the Supermicro X14SDW-64C-SP9F motherboard and delivers the precise rank, voltage and timing that platform expects.

Registered RDIMM with ECC

The 288-pin RDIMM uses a registered architecture that buffers address and command signals, allowing every slot to run fully populated at full capacity. On-die ECC detects and corrects single-bit errors automatically, protecting data integrity in production workloads.

Replaces mismatched or undersized DIMMs

Install this kit when your current memory falls short of the board's supported capacity or when mixed ranks prevent full-speed operation. The jump is worth it when you need guaranteed compatibility at 5600MHz without manual tuning.

Questions about this item

What DDR5 speed and PC5 rating does this 128GB RDIMM run at?

This module operates at DDR5 5600 with a PC5-44800 data rate, the exact speed the Supermicro X14SDW-64C-SP9F memory controller expects for full-capacity operation.

What physical slot and form factor does this 288-pin Registered DIMM require?

It fits a standard 288-pin DDR5 RDIMM socket; the board needs a Registered DIMM slot, not a UDIMM or SODIMM socket, and the module has no heat spreader.

How do I install this 4Rx4 ECC Registered kit in the Supermicro X14SDW-64C-SP9F, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector, press firmly until both retention clips click, then consult the motherboard manual for the approved DIMM population order before powering on.
