384GB DDR5 ECC RDIMM Kit for Supermicro H14SST-GE

This 384GB kit contains eight 48GB DDR5 6400 RDIMM modules built for the Supermicro H14SST-GE motherboard. Registered ECC architecture delivers the stability required by production servers and workstations handling critical data workloads.

Registered 288-pin form factor with 1.1V operation

Each module uses a 288-pin RDIMM connector that matches the board's memory slots exactly. Registered buffering reduces electrical load on the memory controller when all eight slots are populated, while on-die ECC corrects single-bit errors without interrupting service.

DDR5 6400 CL52 2Rx8 specification determines

The kit runs at DDR5 6400 (PC5-51200) with CL52 latency and a 2Rx8 rank organisation at 1.10V. Verify your system manual for supported capacities, approved population order, and maximum DIMM speed before installation.

Questions about this item

Does this kit run at DDR5-6400 on the Supermicro H14SST-GE, or is the speed capped by the platform?

The modules are rated DDR5-6400 (PC5-51200) with CL52 at 1.10 V. The board's memory controller and population rules determine the final operating speed.

Will these 288-pin RDIMMs fit the Supermicro H14SST-GE DIMM slots, and how many modules does the kit contain?

The kit includes eight 48 GB modules, each a 288-pin registered RDIMM. The H14SST-GE requires registered DIMMs, not UDIMMs or SODIMMs.

What is the correct installation order for all eight modules on the H14SST-GE, and which step is commonly missed?

Consult the motherboard manual for the approved population sequence; the step often missed is following the exact slot order for full 384 GB recognition.
