256GB DDR5-6400 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5-6400 (PC5-51200) registered ECC RDIMMs built for the Supermicro X14QBH+ motherboard. It delivers the exact 4Rx4 rank structure, 1.10V operating voltage and CL52 latency the platform expects for full-capacity recognition at rated speed.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all four slots remain stable when fully populated under continuous server workloads. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption during long-running compute or database tasks.

Pre-installation checklist

Verify the motherboard manual for approved DIMM population order, maximum supported capacity per slot and any BIOS version requirements before ordering. Confirm the system accepts 288-pin DDR5 RDIMMs with 4Rx4 organisation and 1.10V operation, as UDIMM or SODIMM modules will not fit or function.
