Capacity and fit

This is a 1.5TB DDR5 ECC Registered RDIMM kit built as twelve 128GB modules for the Supermicro H14DSG-OM motherboard. It delivers PC5-44800 speed at CL46 latency and runs at 1.1V using a 2Rx4 organisation.

Who it suits and who it does not

The kit is intended for administrators expanding a compatible Supermicro server to its full memory population with registered ECC modules. It will not work in systems that require unbuffered UDIMMs, SODIMM form factors, or non-ECC memory, and it cannot be used in platforms limited to lower capacities or different DDR generations.

Installation notes

Each module uses the standard 288-pin RDIMM connector and seats like any registered DIMM, but the board’s population rules must be followed exactly to reach full capacity and rated speed. Common issues include mixing ranks, skipping required slot order, or omitting a BIOS update that the motherboard manual specifies for 128GB DIMMs.

Questions about this item

Does my Supermicro H14DSG-OM motherboard need all 12 DDR5 RDIMM slots filled for this 1.5TB kit to work?

The kit contains 12 modules of 128GB each. Consult the motherboard manual for supported capacities and the required DIMM population order before installation.

Will these 2Rx4 registered ECC DDR5 modules run at 5600MHz alongside any older DDR5 RDIMMs I keep in the system?

Mixing modules with different ranks, timings or voltages can prevent the memory controller from running at the rated 5600MHz CL46 1.1V. Use identical kits for full-speed operation.

How can I verify the kit is running at the rated 5600MHz CL46 1.1V after setup?

Check the memory speed, CAS latency and voltage in the BIOS or UEFI; they should show DDR5-5600 (PC5-44800), CL46 and 1.1V when the system is fully populated.
