System-specific DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 ECC RDIMM memory in a matched pair of 64GB modules. It is built for the Supermicro X14SBW-TF server motherboard and operates at 6400MHz with a CAS latency of 52. The registered 4Rx4 modules run at 1.1V and use 288-pin DDR5 form factor.

Suited for registered-memory servers.

IT administrators expanding a Supermicro X14SBW-TF system gain error-correcting registered memory qualified for that platform. Builders whose boards require unbuffered UDIMMs or non-ECC modules cannot use this kit. The 4Rx4 organisation also demands a memory controller that supports quad-rank registered DIMMs.

128GB (2 x 64GB) DDR5 6400MHz ECC RDIMM capacity

The decisive specification is the 128GB total capacity provided as two 64GB DDR5 6400MHz ECC RDIMM modules. This exact capacity, speed, voltage and registered 4Rx4 configuration determines whether the kit matches the Supermicro X14SBW-TF memory requirements.

Questions about this item

Should I pick the 2x64GB kit or a different capacity for my Supermicro X14SBW-TF?

The kit supplies 128GB total across two 64GB modules, matching the board's DDR5 RDIMM slots and registered ECC requirements for stable server operation.

What does the 6400MHz rating deliver once installed in the X14SBW-TF?

The modules run at DDR5-6400 with CL52 latency at 1.1V, giving the maximum supported throughput for this platform's registered memory controller.

How does the 288-pin DDR5 RDIMM interface limit performance on this motherboard?

The registered 288-pin DDR5 interface caps speed at 6400MHz and requires ECC 4Rx4 modules, so bandwidth is fixed by the board's memory controller specification.
