Speed 4800MHz

  • 768 GB total capacity from twelve 64 GB modules for maximum server density
  • DDR5 4800 speed with CL40 latency runs at rated performance on the memory controller
  • Registered ECC architecture corrects single-bit errors and supports full population stability
  • 10 V operating voltage matches the board's DDR5 power specification exactly
  • 288-pin RDIMM form factor fits the Supermicro H13DSG-OM motherboard slots directly

Exact-Match DDR5 Kit for Supermicro H13DSG-OM

This 768GB kit contains twelve 64GB DDR5 4800 RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSG-OM motherboard expects. Registered ECC architecture allows every slot to run fully populated at rated speed while correcting single-bit errors on the fly. It is intended for administrators upgrading that specific platform.

Thermals Noise and Power Draw

Modules operate at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable across all twelve slots. No active cooling components are present so acoustic output depends entirely on the system fans.

Upgrade Path and When It Makes Sense

The kit replaces smaller-capacity DDR5 RDIMM sets or fills empty slots on the H13DSG-OM to reach the board's maximum supported density. The jump is worth it when workloads demand the full 768GB at native 4800 MT/s with ECC protection. Buyers needing a different form factor, speed or non-ECC memory cannot use this product.

Questions about this item

How do I install the 12 288-pin RDIMM modules in the Supermicro H13DSG-OM and which population step is most often missed?

Follow the motherboard manual for the exact slot-filling sequence; the step most often missed is populating all twelve slots in the prescribed order so the memory controller recognises the full 768 GB at DDR5 4800.

What maintenance or replacement will the 2Rx4 registered ECC kit need over its service life?

The modules have no moving parts and require no scheduled maintenance; replacement is only necessary if a DIMM fails, at which point the lifetime warranty covers a swap.

What limit appears first when the 768 GB kit runs sustained workloads at 1.1 V?

The registered buffer and ECC logic keep every slot stable at the rated DDR5 4800 speed, so the first limit encountered is the motherboard's maximum supported capacity rather than a memory thermal or voltage ceiling.
