  • ECC and registered architecture corrects single-bit errors and offloads the memory controller
  • Verified fitment for Supermicro H14DSG-OM motherboard with 288-pin RDIMM form factor
  • Built with major OEM Samsung, Micron, or Hynix chips for enterprise-grade reliability

Capacity and fit

This 768GB kit contains twelve 64GB DDR5 RDIMMs rated at 5600MHz with CL46 latency and 1.1V operation. The modules use 2Rx4 registered ECC architecture and are validated for the Supermicro H14DSG-OM motherboard.

Suited workloads and limits

The registered ECC design suits servers that need full-slot population with error correction and controller offload. It is not suited for desktop boards that accept only unbuffered UDIMMs, nor for laptops or compact systems requiring SODIMM form factors.

Package contents and effect

The box delivers twelve 288-pin RDIMMs pre-configured as a matched kit, so the memory controller sees identical rank, voltage and timing across every channel. No heat spreaders or software utilities are included.

Questions about this item

Does the Supermicro H14DSG-OM motherboard support a full 12-DIMM population of these 64GB RDIMMs?

The kit is verified for the H14DSG-OM and matches its 288-pin RDIMM requirement, 1.1V operation, 2Rx4 rank structure and DDR5-5600 speed, so all 12 modules can run at rated capacity when installed in the correct slots.

Can I mix these 1.1V DDR5-5600 modules with slower DDR5 RDIMMs already in the system?

The memory controller will down-clock all installed DIMMs to the lowest common speed and adjust timings, but registered ECC modules of different ranks or voltages may prevent the full 768GB from being recognised.

How can I confirm the kit is running at 5600MHz with ECC active after installation?

Check the BIOS memory information screen for DDR5-5600 (PC5-44800) speed, CL46 latency, 1.1V voltage and ECC-enabled status across all 12 DIMMs, then run a memory diagnostic to verify error correction.
