128GB DDR5 6400MHz ECC RDIMM Kit

This 128GB kit contains two 64GB DDR5 6400MHz CL52 modules built for registered ECC server platforms. The 4Rx4 organisation and 1.1V operation match the Supermicro X14SBI-TF memory specification.

Suited for Supermicro X14SBI-TF upgrades

Administrators expanding a Supermicro X14SBI-TF system gain 128GB of registered ECC capacity in two slots. Builders targeting consumer motherboards, non-ECC workstations or platforms that require unbuffered DIMMs should select a different kit.

4Rx4 registered ECC at 6400MHz

The 4Rx4 registered ECC design at DDR5 6400MHz CL52 determines whether the motherboard memory controller can initialise the modules. Verify the platform qualification list before purchase.

Questions about this item

How do I install these 288-pin DDR5 RDIMMs in my Supermicro X14SBI-TF, and what step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 128GB are detected at 6400MHz with ECC active.

What maintenance or replacement will this 4Rx4 registered ECC kit need over time?

No routine maintenance is required; the modules have no heat spreaders and run at 1.1V. If a DIMM fails, replace the faulty 64GB stick — NEMIX RAM offers a lifetime replacement warranty.

What limit appears first when this memory runs sustained workloads on the X14SBI-TF?

The CAS latency of CL52 at 6400MHz sets the timing ceiling; sustained throughput will be bound by that latency before voltage or thermal limits are reached.
