Exact DDR5-4800 ECC RDIMM kit for Supermicro

This 128GB kit delivers four 32GB DDR5-4800 Registered ECC modules built to the board's required 2Rx8 rank, 1.10V voltage and CL40 timing. The 288-pin RDIMM form factor matches the server's memory slots precisely. System integrators upgrading this specific Supermicro platform receive the exact density and electrical profile the memory controller expects.

Registered buffer and on-die ECC protect

The registered architecture reduces electrical load on the memory controller so all four slots run fully populated at rated speed. ECC corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots. Major OEM Samsung, Micron or Hynix DRAM underpins the modules. No heat spreader is included, relying on server chassis airflow.

Motherboard population rules decide if 128GB works

The Supermicro H13DSG-O-CPU-D manual defines supported capacities per channel, approved DIMM order and maximum rank count per processor. If the board limits total capacity or rank population below what this 4x32GB kit provides, the modules will not train at DDR5-4800. Verify the manual before purchase.

Questions about this item

Will the 4x32GB DDR5 4800 kit need any firmware updates or module swaps over its service life?

No firmware updates or module swaps are required; the registered ECC DDR5 modules run at the rated 4800 MT/s speed and 1.10 V voltage for the lifetime of the server.

What is the first limit reached when the Supermicro H13DSG-O-CPU-D runs this 128 GB kit at full load continuously?

The memory controller’s maximum supported DDR5 4800 speed and the four-slot population rule are the limiting factors; all four 32 GB RDIMMs operate at CL40 without downclocking.

How much heat and power does the 2Rx8 registered DDR5 kit produce when the server runs all day?

Each module draws 1.1 V with no heat spreader, so total power stays within the DDR5 4800 specification and airflow from the chassis fans is sufficient for continuous operation.
