SuperMicro DDR5 4800 ECC RDIMM

This 16 GB registered DDR5 module is built for SuperMicro servers and workstations that require ECC error correction. It runs at 4800 MT/s with CL40 latency at 1.1 V and uses a 1Rx8 chip arrangement on a 288-pin RDIMM form factor. The part is validated for SuperMicro system compatibility.

Tool-less DIMM slot insertion

Installation follows the standard DDR5 RDIMM procedure: align the key notch, press firmly until the retention clips engage, and confirm seating. Common issues arise when mixing registered and unbuffered DIMMs or populating slots in an order the motherboard manual does not support, which can prevent the system from posting.

Verify registered ECC support

Before ordering, confirm that your SuperMicro motherboard accepts registered ECC DDR5 RDIMMs and check the qualified vendor list for 1Rx8 modules at 4800 MT/s. Ensure the BIOS version supports the target speed and that the planned slot configuration matches the platform's population guidelines.

Questions about this item

How can I confirm the 16GB DDR5 4800 module is running at CL40 after installation?

Enter the system BIOS or UEFI and check the memory timing table; it should show CAS latency 40 at 4800 MT/s for the installed DIMM.

What comes in the package and what must I source separately?

The box contains one 16GB 288-pin DDR5 RDIMM; no heat spreader or extra cables are included, so nothing else is required for a standard server DIMM slot.

Which capacity and rank should I choose for a SuperMicro system needing registered ECC memory?

This part is a single 16GB 1Rx8 registered ECC RDIMM; select it when your configuration calls for one 16GB module per channel at 1.1V.
