16 GB DDR5-6400 ECC RDIMM for Supermicro H14SHM

This 16 GB DDR5 module runs at 6400 MT/s with CL52 latency and 1.1 V operation. It uses a 1Rx8 registered ECC layout on a 288-pin RDIMM form factor. The part is built as an exact-match upgrade for the Supermicro H14SHM motherboard.

Registered buffer and ECC keep full-speed

The registered architecture offloads the memory controller so every slot can run fully populated at the rated 6400 speed. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during sustained workloads.

Verify DIMM population rules

Server memory support varies by model and BIOS revision. Consult the Supermicro H14SHM manual for supported capacities, required population order, and installation steps to ensure the module is recognised at full capacity and speed.

Questions about this item

How much power does this 1.1 V DDR5 6400 RDIMM draw when the server runs continuously?

The module operates at 1.10 V, the standard DDR5 voltage, so power draw stays within the platform's registered DIMM budget even with every slot populated.

What motherboard slot and population rules must my Supermicro H14SHM already follow to accept this 288-pin registered ECC DIMM?

The board requires 288-pin DDR5 RDIMMs and has a specific population order; consult the H14SHM manual for approved slot sequence and maximum capacity per channel.

Can I mix this 1Rx8 CL52 registered ECC module with other DDR5 RDIMMs of different rank or latency in the same H14SHM system?

Mixing ranks or timings is not recommended; the memory controller expects identical 1Rx8 CL52 modules in each populated channel for stable operation at 6400 MT/s.
