Exact-match DDR5 upgrade for Supermicro H14SST-G

This 32GB kit contains two 16GB DDR5-4800 Registered ECC RDIMMs built to the board's precise rank, voltage and timing requirements. The modules install as a matched pair so the server recognises the full capacity and runs at the rated 4800 MT/s speed without manual tuning.

32GB capacity with registered ECC headroom

Two 1Rx8 modules deliver 32GB total while the registered architecture offloads the memory controller, allowing every populated slot to operate at full rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

288-pin RDIMM form factor decides fit

The kit uses the 288-pin Registered DIMM layout this motherboard requires; it will not work in boards that accept only UDIMM or SODIMM modules. Verify your system manual for supported capacities and population order before ordering.

Questions about this item

Will these DDR5-4800 RDIMMs work with the memory already installed in my Supermicro H14SST-G?

The H14SST-G uses DDR5 slots; this kit matches the board's required DDR5-4800 PC5-38400 1Rx8 Registered ECC spec, so it will run at the rated speed when populated per the manual.

How do I verify the kit is running at DDR5-4800 CL40 1.1V after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 4800 MT/s, CAS 40 and 1.10 V for each 16 GB module.

What comes in the box and is anything else needed to use it?

The package contains the two 16 GB DDR5-4800 ECC RDIMMs; no extra parts are required beyond a compatible Supermicro H14SST-G motherboard and its documentation.
