System-specific DDR5 kit for Supermicro H14DSG-OM

This 128 GB kit contains eight 16 GB DDR5-4800 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. It is intended for administrators who need to populate every slot with validated modules so the server recognises the full capacity at rated speed.

Registered ECC RDIMM with 1Rx8 organisation

The modules use a 1Rx8 layout at 1.1 V with CL40 latency, matching the board's requirement for registered error-correcting memory. Builders who need unbuffered UDIMMs or non-ECC DIMMs cannot use this kit, and systems that demand a different rank structure or voltage will not post with these installed.

Eight-module kit enables full-channel population

The package supplies eight matched 16 GB sticks, allowing all supported channels to be filled in a single purchase. No additional accessories, software or heat spreaders are included, so installers must follow the motherboard manual for correct population order and thermal management.

Questions about this item

What does 4800 MHz mean for my Supermicro H14DSG-OM server?

The modules run at DDR5-4800 (PC5-38400), so each of the eight 16 GB sticks delivers that data rate when the board's memory controller is fully populated.

How does the 288-pin RDIMM interface affect installation?

The kit uses 288-pin DDR5 RDIMM modules; they fit only the registered DIMM slots on the H14DSG-OM and cannot be used in UDIMM or SODIMM sockets.

What physical clearance do the 1Rx8 modules need?

Each 16 GB stick is a standard-height 288-pin RDIMM without a heat spreader, so it fits the regular DIMM spacing defined by the Supermicro H14DSG-OM layout.
