64GB DDR5 6400MHz ECC RDIMM for Supermicro X14SBW-TF

This 64GB DDR5 6400MHz registered DIMM delivers ECC protection and 4Rx4 organisation for the Supermicro X14SBW-TF platform. It operates at 1.1V with CL52 latency and uses 288-pin DDR5 RDIMM form factor. Major OEM Samsung, Micron or Hynix chips provide server-grade reliability.

Server and workstation builders needing registered

This module suits administrators upgrading Supermicro X14SBW-TF systems that require registered ECC DDR5. Builders of consumer desktops, laptops or non-ECC platforms cannot use this registered DIMM. Systems limited to unbuffered memory or lower speeds should select a different kit.

4Rx4 rank configuration decides compatibility

The 4Rx4 organisation determines whether the motherboard memory controller can address the full 64GB capacity. Supermicro X14SBW-TF documentation must confirm support for this rank structure before purchase.

Questions about this item

What does 6400MHz mean for actual throughput in a Supermicro X14SBW-TF?

The module runs at 6400 MT/s, delivering up to PC5-51200 bandwidth when the platform’s memory controller operates at that data rate.

How does the DDR5 RDIMM interface limit usable speed on this board?

The registered DDR5 DIMM connects through the 288-pin slot; the X14SBW-TF’s memory controller caps the final transfer rate, so the kit will run at the highest speed the board officially supports.

Will the 288-pin 4Rx4 registered DIMM fit the X14SBW-TF memory slots?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor with 4Rx4 organisation, matching the slot layout and electrical requirements of the Supermicro X14SBW-TF.
