  • 288-pin RDIMM form factor fits the Supermicro H14SST-G motherboard

Exact-match server upgrade

This 768 GB kit contains sixteen 48 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.10 V operation. It is built for the Supermicro H14SST-G motherboard and will only work in systems that accept 288-pin registered ECC modules.

Thermals noise and power

Registered buffering reduces electrical load on the memory controller when all slots are populated, allowing the full 768 GB to run at the rated 4800 MT/s without extra voltage. The modules operate at the standard 1.10 V DDR5 level and have no heat spreaders, so airflow across the DIMM slots handles cooling.

Registered ECC requirement

The motherboard must support 2Rx8 registered ECC RDIMMs; unbuffered or non-ECC memory will not function in this configuration. Verify the system manual for approved population order and maximum supported capacity before installation.

Questions about this item

How do I install the 16 DDR5 RDIMMs on the Supermicro H14SST-G without violating the board's population order?

Consult the motherboard manual for the exact slot sequence; populate all 16 slots with the 2Rx8 registered modules so the memory controller sees the full 768 GB at DDR5 4800.

What maintenance or replacement will the 768 GB DDR5 ECC kit need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors automatically, and the lifetime replacement warranty covers any module that fails.

What limit appears first when the 16 2Rx8 modules run sustained workloads at 4800 MT/s?

The memory controller's maximum supported capacity and rank-per-channel limit govern sustained operation; the board's population rules define the practical ceiling.
