Capacity and platform fit

This kit provides 64GB of DDR5 memory in two 32GB modules built for the SuperMicro X14SBI-TF server board. It targets administrators who need registered ECC capacity for stable operation in virtualization or database workloads.

Registered ECC design and daily handling

Each module uses a 288-pin RDIMM form factor with a 2Rx4 organisation and runs at 1.1V without a heat spreader. The registered buffer reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors to protect data integrity during continuous uptime.

DDR5 6400 bandwidth ceiling

The PC5-51200 rating sets a maximum transfer rate of 6400 MT/s with CL52 latency. Real-world throughput will depend on the platform's memory controller and the number of populated slots, so sustained bandwidth may fall below the peak specification.

Questions about this item

What speed does the DDR5 6400 interface run at in this kit?

The modules are rated for DDR5 6400 (PC5-51200) with a CAS latency of CL52 and operate at 1.10V.

What physical slot and form factor do these modules require?

Each module uses a 288-pin DDR5 RDIMM form factor and fits standard registered DIMM slots on the SuperMicro X14SBI-TF motherboard.

How do I install the 2Rx4 registered DIMMs and what step is often missed?

Power down the server, open the chassis, align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that both 32GB modules are detected at 6400 MT/s.
