Exact-Match DDR5 ECC RDIMM for Supermicro H13DSG-OM

This 32GB DDR5-4800 Registered ECC module uses a 2Rx8 organisation at 1.1V and CL40 latency. It matches the precise rank, voltage and timing the motherboard's memory controller expects so the system recognises the full capacity and runs at the rated PC5-38400 speed without manual tuning.

Registered Architecture for Full-Population

The Registered (buffered) design offloads the memory controller, allowing every slot to operate fully populated at full capacity under sustained workloads. On-die ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running production tasks.

Direct Replacement for Missing or Smaller DIMMs

This module replaces an absent or lower-capacity stick in a Supermicro H13DSG-OM platform, adding 32GB of DDR5-4800 Registered ECC memory in a single 288-pin RDIMM. The upgrade is worthwhile when the board's population rules allow the target configuration and the workload needs the extra registered ECC capacity at the native 4800MHz data rate.

Questions about this item

How much power does this 32GB DDR5-4800 RDIMM draw at its rated 1.1V?

The module operates at 1.10V, the standard DDR5 RDIMM voltage, so power draw stays within the server platform's registered-DIMM budget even when all slots are populated.

What motherboard slot and memory controller features are required for this 288-pin ECC Registered DIMM?

It needs a DDR5 RDIMM slot on a board that supports registered, 2Rx8 ECC modules — the Supermicro H13DSG-OM is validated for this exact configuration.

Will this DDR5-4800 RDIMM down-clock reliably if installed beside older DDR5 modules running at a lower speed?

Yes, registered ECC DDR5 DIMMs negotiate a common speed with the memory controller, so the kit will run at the highest rate all installed modules and the platform support.
