Exact-match 576GB DDR5 kit

This 576GB kit contains twelve 48GB DDR5-4800 RDIMM modules rated at CL40 and 1.1V. It is built for the Supermicro H14DSG-OM motherboard and delivers the precise rank, voltage and timing the platform expects for full-capacity recognition.

Registered ECC stability

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The modules operate at the standard 1.1V DDR5 voltage without a heat spreader.

Twelve-module population kit

The package supplies exactly twelve 288-pin RDIMMs in a single kit, enabling a complete memory upgrade in one purchase. No additional software or accessories are included beyond the modules themselves.

Questions about this item

How do I install the 12 DDR5 288-pin RDIMMs in the Supermicro H14DSG-OM, and which slot-population step is commonly missed?

Populate all 12 slots following the exact order in the Supermicro H14DSG-OM manual; the step most often missed is using the board-specific population sequence instead of simply filling slots sequentially.

What maintenance or replacement will this 576GB DDR5 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; the modules carry a lifetime replacement warranty, so any failed DIMM is swapped rather than serviced.

What limit appears first when the 12x48GB DDR5-4800 CL40 kit runs sustained workloads on the H14DSG-OM?

The memory controller's maximum supported capacity and ranked-population ceiling for the H14DSG-OM is reached before thermal or bandwidth limits become binding.
