System-specific DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB registered DDR5 modules rated at 6400MT/s with CL52 latency. It is built for the SuperMicro X14SBI-TF server motherboard and uses 2Rx4 ECC chips that operate at 1.10V. The modules are unbuffered by a heat spreader.

Verify registered ECC support and slot count

Your motherboard must accept 288-pin DDR5 RDIMM modules with on-die ECC and registered buffering. Confirm the X14SBI-TF has at least four available DIMM slots and that the BIOS is current enough to initialise 6400MT/s speeds. Registered memory will not function in consumer boards that require unbuffered DIMMs.

Major OEM chips tested under load

Samsung, Micron or Hynix ICs are assembled into a standard-height 288-pin form factor without a heat spreader, allowing tight spacing in dense server chassis. The registered design adds a clock cycle for signal integrity across all four modules. Lifetime replacement warranty backs the validated compatibility.

Questions about this item

Does the 128GB kit include all four 32GB modules or do I need to buy extra sticks?

The package contains four 32GB RDIMM modules for a total of 128GB; no additional sticks are required.

Should I choose the CL52 6400MHz version or a different latency kit for my SuperMicro X14SBI-TF?

This kit is validated for the X14SBI-TF at DDR5 6400 with CL52 latency; select this version to match the board's qualified speed.

What does the 6400MHz rating mean once the memory is installed in the server?

The modules will run at DDR5 6400 (PC5-51200) with 1.10V voltage and CL52 timings when the motherboard applies its default profile.
