Exact-match 128 GB DDR5 ECC RDIMM

This 128 GB DDR5 5600 CL46 4Rx4 registered ECC RDIMM is built for the Supermicro X14SDW-42C-SP9F motherboard. It delivers the precise rank, voltage and timing the server's memory controller expects for full-capacity recognition at rated speed.

Straightforward 288-pin RDIMM install

The module uses the standard 288-pin registered DIMM form factor required by the board — not UDIMM or SODIMM. Follow the motherboard manual for supported capacities, approved population order and installation steps; mismatched population rules are the most common cause of non-recognition.

4Rx4 registered ECC at 1.1 V

The single specification that decides fit is the 4Rx4 registered ECC organisation running at 1.1 V with CL46 timing. If your configuration demands a different rank, voltage or unbuffered DIMM, this module will not meet the requirement.

Questions about this item

How do I verify the 128GB DDR5 5600 CL46 RDIMM is running at its rated 5600MT/s and 1.10V after installation?

Enter the server BIOS or UEFI and confirm the memory frequency shows 5600MT/s (PC5-44800) with 1.10V applied. The POST memory count should report the full 128GB and ECC status as active.

What ships in the box and is anything else required to complete the upgrade?

The package contains one 128GB 288-pin DDR5 5600 CL46 4Rx4 ECC Registered RDIMM. No extra cables, brackets or cooling parts are needed; the module installs directly into the motherboard DIMM slots.

Which capacity or rank option should I choose for the Supermicro X14SDW-42C-SP9F?

This kit is a single 128GB 4Rx4 Registered ECC module matched to the board's DDR5 5600 specification. Select this exact part number when your configuration calls for a 128GB RDIMM of this rank and voltage.
