Exact DDR5-4800 RDIMM for Supermicro H13SST-G

This 16 GB registered ECC module runs at 4800 MHz with CL40 latency at 1.10 V. It is built for administrators who need a single 1Rx8 DIMM that matches the server's memory controller requirements exactly. The registered design allows full-slot population without signal loading issues.

Verify DIMM population rules before ordering

Consult the Supermicro H13SST-G manual for supported capacities per channel, approved slot-filling order and any BIOS version requirements. The board accepts only 288-pin registered DDR5 RDIMMs; unbuffered or SODIMM modules will not fit or function. Ensure your configuration matches the 1Rx8 rank structure.

Bare DRAM with no heat spreader

Major OEM Samsung, Micron or Hynix chips are exposed for direct airflow cooling inside a server chassis. The 288-pin RDIMM connector keys only into registered DDR5 slots, preventing accidental mis-installation. Registered buffering reduces electrical load on the memory controller during continuous operation.

Questions about this item

Does the kit include only the 16GB DDR5 4800MHz RDIMM or are extra parts needed?

The package contains one 16GB DDR5 4800MHz CL40 1Rx8 1.1V 288-pin ECC Registered RDIMM; no additional components are required for installation.

Should I choose this 16GB 1Rx8 CL40 module or a different capacity for my Supermicro H13SST-G?

Select this 16GB 1Rx8 CL40 RDIMM when your board's memory-population rules call for a single-rank registered ECC DIMM at 4800MHz; consult the motherboard manual for approved capacities and slot order.

What does the 4800MHz rating mean once the module is installed in the server?

The module will operate at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V, delivering the exact speed and timing the memory controller expects for full-capacity recognition.
