Exact-match server upgrade

This 2TB kit supplies sixteen 128GB DDR5 RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSG-O-CPU-D memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly. The modules ship new and ready for immediate installation.

DDR5-4800 CL40 1.1V 2Rx4 spec

Each module operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V in a 2Rx4 registered layout on 288 pins. This exact combination of speed, voltage, rank structure and error correction is the single specification that determines whether the board recognises full capacity and sustains rated throughput without down-clocking or training failures.

Sixteen-module kit population

The package delivers all sixteen DIMMs required to fill every slot on the target motherboard in one matched set, eliminating mixed-rank or mixed-vendor populations that can prevent boot or force reduced speeds. Buyers who need a different total capacity or a partial population for a smaller chassis cannot use this kit as sold.

Questions about this item

What does the 4800 MHz speed mean once this kit is installed in the Supermicro H13DSG-O-CPU-D?

The modules run at DDR5-4800 (PC5-38400) with CL40 latency at 1.1 V, delivering the exact data rate and timing the motherboard's memory controller expects for full 2 TB capacity across all populated slots.

How does the 288-pin RDIMM registered ECC interface affect what the system can do?

Registered buffering offloads the memory controller so all 16 slots operate at the rated 4800 MHz, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

What physical space and slot layout does this 16-module kit require?

Each 128 GB module is a standard 288-pin DDR5 RDIMM without a heat spreader; the kit fills 16 DIMM slots, so the board must support that population order and the chassis must provide clearance for full-height modules.
