System-specific DDR5 kit for Supermicro H13DSG-OM

This 512GB kit contains four 128GB DDR5 4800MHz Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13DSG-OM memory controller expects. It targets administrators who need maximum registered capacity on this platform.

Verify DIMM population rules in the manual

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase to ensure correct configuration.

Registered ECC design reduces controller load

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity. ECC catches and corrects single-bit errors on the fly, stopping silent data corruption and unplanned reboots during production workloads.

Questions about this item

Does the 512GB kit include four 128GB modules or do I need to buy them separately?

The kit ships with four 128GB DDR5 RDIMMs pre-packaged together, so no additional modules are required to reach the 512GB total.

Should I choose this 4x128GB 2Rx4 kit or a different capacity for the Supermicro H13DSG-OM?

This 4x128GB 2Rx4 kit matches the motherboard's validated population rules and delivers the full 512GB capacity at the rated 4800MHz speed.

What does the 4800MHz PC5-38400 rating mean once the modules are installed in the server?

The memory controller will recognise each 128GB 2Rx4 RDIMM at 1.1V CL40 and run all four slots at the full 4800MHz data rate with ECC active.
