Exact-fit DDR5-5600 server kit

This 128GB kit comprises four 32GB DDR5-5600 ECC RDIMMs built to the Supermicro X14SDW-72C-SP9F memory specification. Registered 2Rx8 modules at 1.1V and CL46 match the board's controller expectations so the full capacity is recognised at rated speed without manual tuning.

Upgrade from smaller or slower DIMMs

Replacing partial populations or lower-frequency modules lets every slot run fully populated at the rated 5600MT/s data rate. The jump is worthwhile when workloads need the full 128GB address space and the registered architecture that keeps the memory controller stable under sustained load.

DDR5 platform constraints

The 288-pin RDIMM form factor fits only DDR5 server platforms wired for registered ECC memory; it will not seat in UDIMM or SODIMM sockets. Population rules differ by motherboard revision, so the system manual must be consulted for approved slot order and maximum supported capacity before installation.

Questions about this item

Does this kit use the 288-pin RDIMM form factor required by the Supermicro X14SDW-72C-SP9F?

Yes, every module is a 288-pin DDR5 RDIMM, which is the exact registered form factor the X14SDW-72C-SP9F memory slots accept.

What population order should I follow when installing the four 32 GB sticks?

Install the four 2Rx8 modules in the sequence the Supermicro manual specifies for full 128 GB capacity; skipping a slot or mixing ranks will prevent the system from recognising all memory.

How long are these modules covered for replacement if a failure occurs?

The kit carries a lifetime replacement warranty, so any defective DIMM can be exchanged for as long as you own it.
