Exact-Match DDR5 RDIMM for Supermicro X14SDW

This 64GB DDR5-6400 registered ECC module is built to the precise rank, voltage, and timing the Supermicro X14SDW-64CM-SP9F memory controller expects. It delivers 64GB in a single 288-pin RDIMM so the board recognises full capacity at rated speed.

Straightforward 288-pin RDIMM installation

The module seats in the standard DDR5 RDIMM slots using the board's documented population order. Registered buffering offloads the controller, so every slot runs fully populated; the only common issue is ignoring the manual's slot sequence, which can prevent the system from posting at full capacity.

64GB single-module capacity with ECC headroom

One module provides 64GB of registered ECC memory, correcting single-bit errors on the fly to stop silent data corruption. Capacity scales by adding identical modules per the motherboard's supported configuration; the limit is the board's maximum supported memory and approved population rules.

Questions about this item

How do I confirm the module runs at DDR5 6400 with CL52 after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s and the CAS latency reads 52. The registered ECC design ensures the controller recognises the 4Rx4 rank at 1.1 V, so the POST screen should report the full 64 GB capacity without errors.

What ships in the package and do I need extra parts for the Supermicro X14SDW-64CM-SP9F?

The box contains one 64 GB DDR5 6400 PC5-51200 4Rx4 1.1 V CL52 288-pin ECC registered RDIMM. No additional cables, brackets or cooling are required; the motherboard’s 288-pin RDIMM slots accept the module directly.

Which version should I choose if my manual lists 4Rx4 registered ECC at 1.1 V?

Select this exact MR51200-944K1 kit. It matches the 4Rx4 registered ECC layout, 1.1 V operation and CL52 timing your board expects, ensuring full-capacity recognition and rated-speed operation.
