384GB DDR5-6400 ECC RDIMM Kit

This 384GB kit contains four 96GB DDR5-6400 registered ECC RDIMMs built for the Supermicro X14SRA-T motherboard. Each module runs at 1.1V with CL52 latency and a 2Rx4 rank structure. The registered design buffers address and command signals so the memory controller stays stable when all slots are populated. It targets administrators who need maximum supported capacity on this specific platform.

Upgrading from lower-capacity DDR5 RDIMMs

If the board currently runs smaller registered DIMMs at the same 6400 MT/s speed and 1.1V voltage, this kit replaces them to reach the full 384GB limit in a matched set. The jump is worthwhile when workloads such as virtualisation, in-memory databases or large dataset processing exceed the existing memory ceiling. It does not apply to systems using unbuffered UDIMMs or a different DDR generation.

Check motherboard manual for population rules

Before ordering, confirm the X14SRA-T supports 96GB dual-rank modules in all four slots and note the required installation sequence. Verify the BIOS version listed in the manual for full capacity recognition. Ensure the platform uses 288-pin DDR5 RDIMM sockets and that no UDIMM or SODIMM variants are installed. Power and cooling headroom for fully populated registered memory should also be reviewed.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro X14SRA-T motherboard?

Yes, the kit is built as an exact-match upgrade for the Supermicro X14SRA-T. The 288-pin registered form factor matches the board's DDR5 RDIMM slots, and the 2Rx4 rank, 1.1V voltage and CL52 timing meet the controller's expectations for full-capacity recognition.

What is the correct installation order for the four 96GB modules on the X14SRA-T?

Install the modules in the sequence specified in the Supermicro X14SRA-T manual for a four-DIMM population. The board's population rules dictate which slots must be filled first; skipping this step can prevent the system from booting or from seeing the full 384GB.

Do the modules require any ongoing maintenance such as firmware updates or thermal-pad replacement?

No. The RDIMMs have no heat spreaders and no user-serviceable firmware. ECC error correction runs automatically in hardware, and the registered architecture handles signal integrity without intervention. The only future action would be replacing a module if a hardware fault develops.
