Exact-match DDR5 kit for Supermicro H14DSG-OD

This 384 GB kit contains four 96 GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. It is intended for administrators who need to populate every slot with validated modules that the firmware recognises at full capacity and rated speed.

384 GB capacity with registered ECC headroom

The four 2Rx4 modules deliver 384 GB of addressable memory while the registered architecture offloads the memory controller so every slot runs fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The kit stops at the board's maximum supported population; systems requiring more memory need a different platform.

288-pin RDIMM form factor for direct installation

Each module uses the 288-pin RDIMM form factor this motherboard requires, not UDIMM or SODIMM, and operates at 1.1 V with CL52 latency. Installation follows the board's specific population order, so the manual must be consulted before purchase. No heat spreader is included, leaving clearance for dense server chassis airflow.

Questions about this item

Will this 384GB DDR5 6400 kit work with the Supermicro H14DSG-OD board I already have?

The kit is an exact-match upgrade verified for the Supermicro H14DSG-OD motherboard. It uses the 288-pin RDIMM form factor, 1.1V voltage, 2Rx4 rank and CL52 timing that the board's memory controller expects.

How can I confirm the DDR5 6400 modules are running at full speed after installation?

Enter the BIOS and verify the memory speed shows 6400 MT/s (PC5-51200) with CL52 latency and 1.1V applied. The registered ECC design lets every slot run fully populated at the rated specification.

What comes in the box and do I need anything else to install it?

The box contains four 96GB DDR5 6400 RDIMM modules for a total of 384GB. No heat spreaders or extra cables are included; install directly into the motherboard's DIMM slots following the population order in your system manual.
