  • Built with major OEM Samsung, Micron or Hynix chips for enterprise-grade reliability

Exact-match upgrade kit

This 384GB kit contains four 96GB DDR5 6400 RDIMM modules built to the Supermicro X14SDW-64C-SP9F memory-population rules. Each module is a 2Rx4 registered ECC DIMM running at 1.1V with CL52 timing. The 288-pin form factor matches the board's DDR5 slots exactly.

Who this suits and who it does not

Server builders populating all four channels of an X14SDW-64C-SP9F with the maximum validated capacity will use this kit. Buyers who need a different capacity, speed, rank configuration or unbuffered UDIMM modules cannot use this kit. Systems that require SODIMM or a non-ECC memory type are also incompatible.

Deciding specification

The motherboard requires registered DDR5 RDIMMs at 6400 MT/s with 2Rx4 organisation and 1.1V operation; this kit matches that exact combination. If your platform demands a different speed, voltage, rank or form factor, the modules will not be recognised or will not run at rated performance.

Questions about this item

Will this 384GB kit work in my Supermicro X14SDW-64C-SP9F without adding other modules?

Yes, the kit provides four 96GB DDR5 6400 RDIMMs that match the board's required 288-pin registered ECC form factor, 1.1V voltage, and CL52 timing for full-capacity recognition.

Can I keep my existing DDR5 RDIMMs and add this 4x96GB kit to the same server?

Only if the current modules are also DDR5 6400 registered ECC 2Rx4 at 1.1V with identical CL52 timing; otherwise the memory controller will downclock or reject the mixed population.

How do I confirm the server sees all 384GB at the rated 6400 MT/s after installation?

Enter the BIOS or use a tool like dmidecode to verify each slot shows 96GB, speed reads 6400 MT/s (PC5-51200), and ECC registered mode is active.
