Exact-match DDR5 kit for Supermicro H14SHM

This 768GB kit contains six 128GB DDR5 6400 RDIMMs built to the memory controller's precise rank, voltage and timing requirements. Each module is a 288-pin registered ECC DIMM operating at 1.1V with CL52 latency, so the server recognises the full capacity at rated speed.

Registered ECC limits and population rules

Registered architecture buffers the address and command bus, allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. The motherboard manual defines the supported capacities, approved DIMM population order and any maximum per-channel limits that govern installation.

6x128GB 2Rx4 CL52 at 1.1V

The combination of six dual-rank 2Rx4 modules at CL52 and 1.1V is the single specification that determines whether this kit matches the board's validated configuration. Buyers who need a different capacity per module, rank structure or latency should verify the manual before ordering.

Questions about this item

Should I choose the 6 x 128 GB kit or a different capacity for my Supermicro H14SHM?

The 768 GB kit provides six 128 GB RDIMMs; populate all six slots to reach the full capacity your board supports.

What does the DDR5 6400 speed mean once the modules are installed in the server?

The memory controller will run the kit at 6400 MT/s with CL52 latency at 1.1 V, delivering the rated bandwidth when all slots are filled.

How does the 288-pin RDIMM interface and registered design affect real-world limits?

Registered buffering lets every slot run fully populated at 6400 MT/s while ECC corrects single-bit errors on the fly.
