Supermicro X14SBW-F DDR5 RDIMM Kit

This 256GB kit delivers two 128GB registered DDR5 modules built for the Supermicro X14SBW-F platform. ECC and registered buffering provide the data integrity and signal stability required in enterprise server workloads. The kit operates at 6400MHz with a CAS latency of 52 at 1.1V.

IT Teams Running Memory-Intensive Server Roles

Suits administrators scaling virtualisation hosts, in-memory databases or AI inference nodes on the validated Supermicro platform. Builders needing unbuffered UDIMMs, non-ECC modules or consumer desktop memory should look elsewhere as this kit is registered ECC RDIMM only.

256GB Registered Capacity With DDR5 6400MHz Headroom

The dual 128GB 4Rx4 modules fill two slots for large dataset caching and multi-tenant VM density. Headroom exists for workloads that benefit from high bandwidth at 6400MHz. Systems requiring more than 256GB per channel or lower latency than CL52 will need a different configuration.

Questions about this item

What motherboard slot and memory type are required for these 288-PIN DDR5 RDIMMs?

A Supermicro X14SBW-F motherboard with DDR5 RDIMM slots is required; the kit uses 288-PIN DDR5 registered modules that only fit DDR5 RDIMM sockets.

Will these CL52 6400MHz modules downclock automatically if the board only supports lower DDR5 speeds?

Yes, DDR5 RDIMMs negotiate speed with the memory controller, so they will run at the highest speed the Supermicro platform allows.

How can I confirm the kit is running at 6400MHz with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode to verify 6400MHz data rate, CL52 timings and ECC enabled on both 128GB modules.
