Exact DDR5 ECC kit for Supermicro X14SAE

This 128 GB kit delivers four 32 GB DDR5 4800 UDIMMs built to the board's 2Rx8, 1.1 V, CL40 specification. It targets administrators upgrading a Supermicro X14SAE platform that requires unbuffered ECC memory.

Four ranks per module at DDR5 4800

Each 32 GB module uses a 2Rx8 organisation, giving the memory controller the rank density it expects for full-speed operation. Workloads that exceed 128 GB or need registered DIMMs will not be supported by this kit.

No heat spreaders or software included

The package supplies only the four UDIMMs in a protective tray. Thermal management relies on chassis airflow, and no configuration utilities or monitoring tools are bundled.

Questions about this item

Will this DDR5-4800 2Rx8 ECC kit run correctly with older DDR5 modules I keep in the Supermicro X14SAE?

Mixing ranks, speeds or voltages can prevent the board from training at 4800 MT/s; the manufacturer recommends populating all slots with identical 2Rx8 1.1 V CL40 modules for guaranteed operation.

How can I verify the 128 GB kit is detected at full speed after installation?

Enter the BIOS and confirm all four DIMMs show 32 GB each, total 128 GB, running at DDR5-4800 with ECC enabled and CL40 timings.

What exactly ships in the box and what must I source separately?

The package contains four 32 GB DDR5-4800 ECC UDIMMs; no heat spreaders, cables, tools or additional components are included.
