  • ECC registered design protects data integrity
  • 1V operation reduces power draw
  • Validated for Supermicro X14SBI-F compatibility

Capacity and purpose

This 128 GB DDR5 kit contains two 64 GB ECC RDIMM modules rated at 6400 MHz CL52 and 1.1 V. It is built for the Supermicro X14SBI-F platform and targets administrators who need registered, error-correcting memory for server or workstation workloads.

Fit and limits

The kit suits IT teams deploying memory in the validated Supermicro X14SBI-F system where 4Rx4 registered DIMMs are required. Buyers who need unbuffered UDIMMs, non-ECC modules, a different pin count, or capacities outside the 2 x 64 GB configuration should look at other products.

Installation notes

Installation follows the standard 288-pin DDR5 RDIMM procedure and typically takes minutes per the manufacturer guidance. Common issues include failing to seat both modules fully in the correct slots, mixing ranks or speeds with existing DIMMs, and skipping the BIOS memory training step that registered memory often requires.

商品問答

Does the Supermicro X14SBI-F motherboard need a specific BIOS version to recognise the 6400MHz CL52 4Rx4 RDIMM kit?

The kit is designed for the Supermicro X14SBI-F and uses standard DDR5 JEDEC 6400MHz timings, so the board will detect it at supported speeds with a current BIOS.

Can I mix these 4Rx4 registered ECC modules with older 2Rx8 DDR5 RDIMMs already installed in the server?

Mixing different rank organisations (4Rx4 vs 2Rx8) on the same channel is not recommended; populate each channel with identical modules for stable operation.

How do I confirm the 128GB kit is running at 6400MHz with ECC active after installation?

Check the POST memory summary or the BIOS memory information screen — it will show 128GB total, 6400MHz speed, and ECC enabled for each DIMM.
