256GB DDR5-4800 ECC RDIMM Kit

This kit delivers 256GB of DDR5-4800 registered ECC memory in eight 32GB modules. It is built for the Supermicro H13DSG-O-CPU motherboard and matches the exact rank, voltage, and timing the memory controller expects. Each 288-pin RDIMM runs at 1.1V with CL40 latency and 2Rx8 organization. The registered buffer lets every slot run fully populated at rated speed.

Server builds needing maximum capacity per slot

Administrators upgrading a Supermicro H13DSG-O-CPU platform to its full memory limit will use this exact-match kit. Workstations that require unbuffered UDIMMs or SODIMM form factors cannot accept these registered RDIMMs. Systems limited to lower densities per DIMM or a different DDR generation should look elsewhere.

DDR5-4800 2Rx8 Registered ECC spec

The DDR5-4800 (PC5-38400) 2Rx8 registered ECC specification at 1.1V and CL40 decides compatibility. The motherboard must support this speed, rank, voltage, latency, and registered buffering for the kit to be recognized at full capacity and run at its rated frequency.

Questions about this item

Does DDR5 4800 (PC5-38400) run at its rated speed on the Supermicro H13DSG-O-CPU?

Yes, the kit is spec-matched to the board's memory controller so all 256GB are recognized and run at DDR5 4800 with CL40 timings.

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

The modules are 288-pin Registered RDIMMs; they only fit DDR5 RDIMM slots on the Supermicro H13DSG-O-CPU and will not work in UDIMM or SODIMM sockets.

How do I install the 8x32GB kit in the correct population order?

Consult the Supermicro H13DSG-O-CPU manual for the approved DIMM population sequence, then seat each 32GB RDIMM firmly until the ejector clips click.
