Exact-match DDR5 kit for Supermicro X14SDI-36C-SP3F

This 128GB kit (4 x 32GB) delivers DDR5 6400 (PC5-51200) with CL52 latency at 1.1V. Registered ECC RDIMM modules use 2Rx4 organisation and 288-pin form factor. Built for the Supermicro X14SDI-36C-SP3F motherboard where precise rank, voltage and timing are required for full-capacity recognition.

Fits the board's memory population rules

The 288-pin RDIMM form factor matches the slots this motherboard requires — not UDIMM or SODIMM. Registered architecture offloads the memory controller so every slot runs fully populated at rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

Kit contains four matched 32GB modules

Packaged as a single 128GB kit with four 32GB RDIMMs tested together for consistent timing and voltage. No heat spreaders are included, relying on server chassis airflow. Verify your system manual for supported capacities, approved DIMM population order and installation steps before adding this kit.

Questions about this item

What is the CAS latency of these DDR5-6400 modules?

The kit runs at CL52 timing as specified for the DDR5-6400 speed grade.

How much power do the 1.1 V registered DIMMs draw under continuous load?

Each module operates at 1.1 V; registered buffering reduces electrical load on the memory controller when all four slots are populated.

Which motherboard must I already have for this kit to function?

The memory is validated for the Supermicro X14SDI-36C-SP3F motherboard that requires 288-pin DDR5 RDIMMs.
