Exact-Match DDR5 RDIMM Kit for Supermicro H14DSG-OM

This 1.5TB kit delivers twelve 128GB DDR5 4800 Registered ECC modules built to the precise rank, voltage and timing the motherboard expects. It is designed for server administrators who need full-capacity population across every slot without manual tuning.

Sustained Enterprise Stability

Registered architecture offloads the memory controller so all twelve slots run fully populated at rated speed, while on-die ECC corrects single-bit errors in real time. The 1.1V operation keeps thermal output consistent under continuous multi-threaded workloads typical of virtualisation and database tiers.

Guided Installation and Population Rules

The 288-pin RDIMM form factor fits only the correct DIMM slots; UDIMM or SODIMM modules will not seat. Consult the board manual for the approved population sequence and maximum supported capacity per channel before installing, as incorrect order prevents boot.

Questions about this item

How much heat does a fully populated 12-module kit generate at the rated 1.10V and 4800 speed?

Each DDR5 RDIMM runs at 1.10V with a CL40 timing, and the registered buffer reduces electrical load on the memory controller, helping keep thermals manageable even when all 12 slots are filled.

Does the Supermicro H14DSG-OM require a specific CPU generation or BIOS revision to recognise the full 1.5TB capacity?

The kit is spec-matched to the H14DSG-OM motherboard's 288-pin RDIMM slots and population rules; consult the board manual for supported CPU generations, approved DIMM order and any BIOS updates needed.

Can I add this 12x128GB 2Rx4 kit alongside smaller capacity RDIMMs already installed in the same server?

The board's memory-population rules dictate which slot combinations are allowed; mixing ranks and capacities is only supported when the manual's approved configurations are followed.
