Exact DDR5-4800 upgrade for Supermicro

This 96GB kit delivers two 48GB DDR5-4800 Registered ECC RDIMMs built to the board's required 288-pin form factor. The CL40 1.1V 2Rx8 specification matches the memory controller so the system recognises full capacity at rated speed. It is intended for administrators who need a validated, single-SKU memory expansion for this specific Supermicro server platform.

Registered ECC stability under sustained load

Registered buffering offloads the memory controller so every slot runs fully populated without signal degradation during continuous operation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots that would interrupt production workloads. The 1.1V operating voltage maintains consistent power draw across extended duty cycles.

Guided installation with population rules

The 288-pin RDIMMs seat in the motherboard's DDR5 DIMM slots, but the Supermicro H13DSG-O-CPU-D enforces a strict population order that must be followed from the system manual. Installing modules in the wrong sequence or mixing ranks will cause the board to halt at POST or report reduced capacity. Verify the approved slot layout and maximum supported density per channel before fitting the kit.

Questions about this item

Does the 1.1 V DDR5-4800 kit generate noticeably more heat when the server runs at full load all day?

The modules operate at the standard DDR5 voltage of 1.1 V and have no heat spreader, so thermal output matches typical registered DDR5 DIMMs; ensure your chassis airflow follows Supermicro's population guidelines.

What must the Supermicro H13DSG-O-CPU-D motherboard already provide for this 2Rx8 RDIMM kit to function?

The board needs DDR5 RDIMM slots that support registered ECC memory at 4800 MT/s, 1.1 V operation, and the correct population sequence for 2Rx8 modules as detailed in the motherboard manual.

Will the CL40 DDR5-4800 modules run at rated speed alongside other DDR5 RDIMMs I keep in the remaining slots?

All installed DDR5 RDIMMs must share the same voltage, registered ECC design, and supported speed; the motherboard will train every slot to the lowest common timing, so matching CL40 4800 MT/s modules is recommended.
