SuperMicro X14SBW-F DDR5 RDIMM kit

This 64GB kit contains two 32GB DDR5 6400 CL52 ECC registered DIMMs built for the SuperMicro X14SBW-F motherboard. It targets administrators and integrators who need validated, server-grade memory for that specific platform.

ECC registered modules with 1.1V operation

The registered design and on-die ECC protect data integrity under sustained workloads while the 1.10V voltage reduces power draw per module. No heat spreaders are included, so airflow in the chassis must handle thermal management.

64GB total capacity across two slots

Dual-rank 2Rx4 organisation fills two 288-pin slots and suits virtualization, database or AI inference tasks that fit within 64GB. Workloads requiring more memory or non-registered DIMMs will need a different configuration.

Questions about this item

Will the 2Rx4 DDR5 RDIMMs need any firmware updates or heat-spreader maintenance over time?

No firmware updates are required for the modules themselves, and the kit ships without heat spreaders so there is no spreader maintenance.

What sustained-throughput ceiling appears first when the memory runs at 6400 MT/s CL52 in a SuperMicro X14SBW-F?

The CL52 latency at 6400 MT/s sets the primary timing ceiling; bandwidth is capped by the PC5-51200 data rate of each 32 GB module.

How much power and heat does the 1.10 V 64 GB kit generate during all-day server workloads?

At 1.10 V the two 32 GB RDIMMs draw minimal power and produce low heat, aided by the registered buffer and lack of heat spreaders.
