Exact-match DDR5-6400 kit for Supermicro

This 64GB kit contains two 32GB DDR5-6400 ECC Registered RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDW-36CE-SP9F memory controller expects. It is intended for administrators upgrading that specific server platform with validated modules that populate every slot at full rated speed.

Registered DDR5 RDIMM limits and population rules

Registered (buffered) architecture offloads the memory controller so all slots can run fully populated at 6400 MT/s while ECC corrects single-bit errors on the fly. The motherboard manual defines supported capacities, approved DIMM population order and any per-channel limits; exceeding those rules will prevent the system from posting at the rated speed.

Bare modules with 288-pin RDIMM connectors

The sticks ship without heat spreaders, relying on server chassis airflow for cooling. Their 288-pin Registered form factor fits only DDR5 RDIMM slots — not UDIMM or SODIMM sockets — so they cannot be used in workstations or laptops that require unbuffered or small-outline modules.

Questions about this item

Should I choose the 64GB kit or a different capacity for the Supermicro X14SDW-36CE-SP9F?

This kit provides 64GB as two 32GB modules (2Rx4). The motherboard manual lists supported capacities and the required population order; follow that guide to select the correct total capacity for your configuration.

What does the DDR5-6400 (PC5-51200) speed rating mean once the modules are installed?

The memory controller will run the kit at 6400 MT/s with CL52 latency at 1.1V, delivering the rated bandwidth when the board is populated according to its validated rules.

Is the 288-pin RDIMM interface compatible with the Supermicro X14SDW-36CE-SP9F?

Yes. The board requires 288-pin Registered DDR5 RDIMMs; this kit matches that form factor, voltage, and ECC specification so every slot can be fully populated.
