Eight 96 GB registered DDR5 ECC modules at 6400 MT/s CL52, 1.1 V, built for SuperMicro X14SBI-F servers
This 768GB kit contains eight 96GB DDR5 6400 ECC RDIMM modules built for the SuperMicro X14SBI-F platform. Registered buffering and on-die ECC protect data integrity in continuous server workloads. IT teams specify this density when virtualisation hosts or database nodes demand maximum capacity per channel. The CL52 latency and 1.10V operation match the board's qualified memory profile.
DDR5 6400 (PC5-51200) sets the peak transfer rate; actual throughput depends on the memory controller and populated slot count. Registered RDIMMs add one cycle of command buffering, which stabilises heavy loads but does not reduce the CAS latency of 52 cycles. The 288-pin form factor fits only DDR5 server sockets; it cannot be used in desktop or laptop platforms. Mixing ranks or speeds will force the controller to downclock the entire array.
Each 96GB 2Rx4 module occupies a single DIMM slot, so eight slots are required to reach 768GB. Systems with fewer than eight DDR5 RDIMM slots cannot use this kit at full capacity. Boards that support only 1Rx8 or 2Rx8 organisations may not recognise the 2Rx4 density. Verify the X14SBI-F memory population rules before ordering to avoid a configuration that will not POST.

The kit provides 768GB total using eight 96GB modules, filling eight slots on the X14SBI-F. Choose this when the workload needs maximum registered ECC capacity; a smaller kit leaves slots open for later expansion.
The modules run at DDR5 6400 with CL52 latency at 1.1V, delivering the rated transfer rate when the platform memory controller supports that speed.
The 288-pin DDR5 RDIMM form factor with registered buffering reduces electrical load on the memory controller, allowing all eight 2Rx4 modules to operate at the specified 6400 speed.
