Supermicro H13DSG-OM DDR5 upgrade kit

This 768GB kit contains six 128GB DDR5-4800 RDIMMs built for the Supermicro H13DSG-OM motherboard. Each module is a 288-pin registered ECC DIMM running at 1.1V with CL40 latency, matching the board's memory controller requirements exactly.

Registered ECC design for full population

The registered architecture buffers address and command signals so all six slots can run fully populated at rated speed without overloading the memory controller. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unexpected reboots in production workloads.

Replaces partial or slower DDR5 configurations

Install this kit when your current H13DSG-OM system has fewer than six modules, lower-capacity DIMMs, or mixed-speed memory that forces the controller to downclock. The jump is worth it when workloads need the full 768GB address space at DDR5-4800 with consistent ECC protection.

Highlights

  • 768 GB total capacity from six 128 GB modules
  • DDR5-4800 speed with CL40 latency for rated throughput
  • Registered ECC architecture corrects single-bit errors on the fly
  • 1 V operation matches the server memory controller specification
  • 288-pin RDIMM form factor verified for Supermicro H13DSG-OM

Questions about this item

Does the DDR5-4800 (PC5-38400) interface run at its full rated speed on the Supermicro H13DSG-OM?

Yes, the kit is spec-matched to the board's memory controller so the 4800 MT/s data rate and CL40 timing are recognised and used at full capacity across all populated slots.

What physical slot and form factor do these 128 GB modules require on the H13DSG-OM?

They are 288-pin DDR5 RDIMMs, the registered form factor the board requires; UDIMM or SODIMM modules will not fit or function.

What is the critical installation step for this 6-module kit on the H13DSG-OM?

Follow the motherboard manual's exact DIMM population order for six registered DIMMs; skipping the prescribed sequence is the most common cause of the kit not being recognised at 768 GB.
