Capacity and configuration

This kit provides 256GB of DDR5 memory in eight 32GB RDIMM modules rated at 6400 MT/s with CL52 latency. It is built for Supermicro servers and workstations that require registered ECC memory for data-integrity workloads.

Compatibility checks

Verify that your Supermicro X14SBI-F or other target platform supports 2Rx4 registered DDR5 RDIMMs at 1.1V and can populate all eight slots with this capacity. Confirm the BIOS revision accepts PC5-51200 speeds and that the memory controller handles the full 256GB kit without downclocking.

Sustained-load behaviour

Registered ECC modules maintain error correction and signal integrity during continuous server workloads such as virtualization, database processing and AI inference. The 1.1V operating voltage helps limit thermal output while the 2Rx4 organization supports stable throughput across all populated channels.

Questions about this item

Does the 256GB kit include eight 32GB modules or do I need to buy additional sticks?

The kit contains eight 32GB DDR5 RDIMM modules for a total of 256GB; no extra sticks are required.

Should I pick this CL52 6400 kit or a lower-latency alternative for my Supermicro X14SBI-F?

This CL52 kit matches the validated speed and timing for the X14SBI-F; a lower-latency set may not be supported by the platform.

What does the 6400 MT/s rating deliver once the modules are installed in the server?

The memory runs at 6400 MT/s (PC5-51200) with ECC and registered buffering, providing the bandwidth and error correction the X14SBI-F platform expects.
