Exact-match DDR5-5600 ECC RDIMM kit

This 256GB kit contains eight 32GB registered DDR5 modules rated at 5600 MT/s with CL46 latency and 1.1V operation. It is built for the Supermicro H14SHM motherboard and targets administrators who need the precise rank, voltage and timing the platform expects for full-capacity recognition.

Registered 288-pin form factor with ECC

Each module uses a 288-pin RDIMM layout without a heat spreader, matching the board's required registered architecture. The buffered design offloads the memory controller so all slots run fully populated, while on-die ECC corrects single-bit errors to prevent silent data corruption and unplanned reboots.

Replaces mismatched or partial DDR5 configurations

The eight-module kit eliminates the risk of mixing ranks, speeds or vendors that can limit capacity or disable ECC. The jump is worth it when the server must run every DIMM slot at the rated 5600 MT/s with registered ECC stability. It is not for systems that require UDIMM, SODIMM or non-ECC memory.

Questions about this item

Does DDR5 5600 (PC5-44800) run at 5600 MT/s on the Supermicro H14SHM?

Yes, the kit is rated DDR5 5600 (PC5-44800) and the modules operate at 5600 MT/s when the board's memory controller is configured for that speed.

What physical slot and form factor do these 288-pin RDIMMs require?

They require standard 288-pin DDR5 RDIMM slots on the Supermicro H14SHM; UDIMM or SODIMM slots will not accept the registered form factor.

In what order should the eight 32 GB modules be populated on the H14SHM?

Follow the motherboard manual's approved DIMM population sequence for eight 2Rx8 RDIMMs to ensure full 256 GB capacity and correct channel interleaving.
