Exact-match DDR5 server kit

This 256 GB kit ships as two 128 GB DDR5-4800 RDIMMs built to the CL40 1.1 V 2Rx4 specification your Supermicro H14DSG-OM memory controller expects. Registered ECC architecture corrects single-bit errors on the fly and keeps every slot stable at full capacity.

288-pin registered form factor

The modules use the 288-pin RDIMM layout this board requires; UDIMM or SODIMM modules will not fit or function. Major OEM Samsung, Micron or Hynix components are mounted without heat spreaders, so clearance inside dense server chassis is maximised and airflow is unrestricted.

Lifetime replacement and US support

The package contains only the two matched RDIMMs; no cables, drivers or management software are included. A lifetime replacement warranty and free US-based technical support cover compatibility verification and installation guidance before deployment.

Questions about this item

Does the DDR5 4800 PC5-38400 interface run at its rated speed on the Supermicro H14DSG-OM?

Yes, the kit is spec-matched to the board's memory controller so the 4800 MT/s data rate is recognised and runs at full speed.

What physical slot and form factor does this 288-pin RDIMM kit require?

It fits standard 288-pin DDR5 RDIMM slots; the motherboard uses registered DIMM sockets, not UDIMM or SODIMM.

What is the correct population order when installing both 128 GB modules?

Follow the Supermicro H14DSG-OM manual's DIMM population sequence; installing in the wrong slots can prevent the system from recognising the full 256 GB capacity.
