Exact-fit DDR5 kit for Supermicro H14SHM

This 1.5 TB kit contains twelve 128 GB DDR5-5600 registered ECC RDIMMs built to the Supermicro H14SHM motherboard's qualified-vendor list. The 288‑pin modules operate at 1.1 V with CL46 latency and a 2Rx4 rank structure, so the memory controller recognises every slot at full capacity without manual tuning. It is intended for administrators who need the precise part-number match rather than a generic server DIMM.

Registered buffer and ECC under full population

Because each module is registered, the memory controller sees only one electrical load per slot even with all twelve DIMMs installed, allowing sustained throughput at the rated 5600 MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualised workloads. The 1.1 V operating voltage keeps power draw predictable across the fully populated chassis.

Twelve-module 1.5 TB capacity gate

The kit delivers exactly 1.5 TB only when all twelve 128 GB RDIMMs are populated; any empty slot reduces total capacity proportionally and may change the supported memory-channel topology. Buyers who need a smaller footprint or a different rank configuration should verify the motherboard's population rules before ordering.

Questions about this item

How much power does the 1.5 TB kit draw when the server runs continuously?

Each 128 GB module operates at 1.10 V; the DDR5 standard moves voltage regulation onto the DIMM, so total draw depends on how many of the 12 slots the H14SHM populates and the workload intensity.

What must the motherboard provide for these 288-pin RDIMMs to function?

The Supermicro H14SHM must support DDR5 Registered ECC memory, accept 2Rx4 modules at 5600 MT/s, and follow its documented population rules for up to 1.5 TB.

Will these 5600 CL46 2Rx4 registered DIMMs run at rated speed beside slower DDR5 modules already installed?

The memory controller will clock all populated slots to the lowest common speed and latency; mixing ranks or timings can prevent the kit from reaching 5600 MT/s CL46.
