Exact-match server memory kit

This 128GB kit contains four 32GB DDR5-6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14SHM expects. Each module runs at 1.1V with CL52 latency and a 2Rx8 organisation so the memory controller recognises the full capacity at rated speed.

Registered RDIMM form factor for full population

The 288-pin Registered design is the only form factor the H14SHM accepts, not UDIMM or SODIMM. Registered architecture offloads the memory controller, allowing every slot to be populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Sustained enterprise stability

ECC protection operates continuously under sustained workloads, catching and correcting errors before they reach production. Registered buffering keeps electrical loading stable across all four slots during extended operation, maintaining rated DDR5-6400 throughput without the signal degradation seen in unbuffered configurations.

Questions about this item

What thermal or noise impact should I expect from this 128 GB DDR5-6400 kit running continuously in a Supermicro H14SHM?

The modules operate at 1.1 V with no heat spreader, so they rely on chassis airflow; registered ECC RDIMMs have no moving parts and add negligible acoustic load.

Which components must already be installed for this 4×32 GB DDR5 RDIMM kit to function?

A Supermicro H14SHM motherboard with four free 288-pin DDR5 RDIMM slots and a BIOS that supports 2Rx8 registered ECC modules at 6400 MT/s.
