  • 288-pin RDIMM form factor fits the Supermicro H14SHM memory slots precisely

Exact-match DDR5 server upgrade

This 768 GB kit contains eight 96 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10 V operation. Registered ECC architecture and 2Rx4 organization match the Supermicro H14SHM motherboard requirements so every slot runs at full capacity.

Suited for fully populated H14SHM builds

Ideal for administrators expanding a Supermicro H14SHM server to its maximum supported memory with validated rank, voltage and timing parameters. Not intended for boards that require unbuffered UDIMMs, SODIMM form factors or lower-density modules.

Fits registered DDR5 slots on H14SHM

The 288-pin RDIMMs install directly into the motherboard's registered DDR5 channels, offloading the memory controller and enabling ECC error correction across all eight modules. No heat spreaders are included, so chassis airflow must handle thermal management.

Questions about this item

Does this kit require a Supermicro H14SHM motherboard with 288-pin DDR5 RDIMM slots to operate?

Yes, the 8-module kit is built for the Supermicro H14SHM and uses the 288-pin RDIMM form factor that board expects.

Will the registered ECC design and 2Rx4 organisation work with other registered DDR5 modules already installed in the server?

The modules are registered ECC 2Rx4 at 1.1 V and CL52; mixing different ranks or timings can prevent full-speed operation, so populate all eight slots with this kit for guaranteed stability.

How can I confirm the system sees the full 768 GB at DDR5-6400 with ECC active after installation?

Check the BIOS memory information screen — it should report 768 GB total, 6400 MT/s speed, and ECC enabled for each of the eight 96 GB DIMMs.
