Exact-fit DDR5-5600 kit for Supermicro H14SHM

This 768GB kit contains six 128GB DDR5 Registered DIMMs rated at 5600MHz PC5-44800 with CL46 latency and 1.1V operation. Each module uses a 2Rx4 organization and ECC to protect data integrity in multi-socket server workloads. The 288-pin RDIMM form factor matches the board's registered memory slots exactly.

Replaces partial or slower memory populations

Swapping a mixed-capacity or lower-speed configuration for this full 6x128GB kit lets the memory controller run every channel at the rated 5600MHz without down-clocking. The jump is worth it when your current DIMMs force a reduced frequency, limit total addressable capacity, or lack the registered buffering required for full-slot stability.

Verify DIMM population rules before ordering

Supermicro H14SHM memory support varies by BIOS revision and CPU SKU; the manual lists approved slot sequences and maximum per-channel capacity. Confirm that your firmware revision supports 128GB Registered modules in all six slots and that the installation order matches the vendor's population table.

Questions about this item

Will the 288-pin RDIMM modules fit the DIMM slots on the Supermicro H14SHM motherboard?

Yes, the 288-pin RDIMM form factor matches the slot type required by the H14SHM, so the modules seat correctly without adapters.

What is the correct installation sequence for the six 128GB modules on the H14SHM?

Populate the slots in the exact order listed in the motherboard manual; the most common mistake is skipping a required channel or mixing population rules.

When should I expect to replace the 1.10V DDR5 ECC RDIMM kit?

The kit is covered by a lifetime replacement warranty, so replacement is only needed if a module fails or capacity requirements change.
