Exact-match DDR5-6400 kit for Supermicro H14DSG-OM

This 256GB kit contains four 64GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 timings and 1.1V operation. Registered ECC architecture with 2Rx4 organisation offloads the memory controller and corrects single-bit errors. It is built for the Supermicro H14DSG-OM motherboard and will not fit boards that require UDIMM or SODIMM modules.

Check your system documentation before ordering

Verify that your motherboard revision supports 256GB total capacity and confirm the approved DIMM population sequence for four registered modules. The board must accept 288-pin RDIMMs at 1.1V with 2Rx4 rank structure. Consult the manual for any BIOS version requirements or slot-filling rules that apply to this configuration.

Thermals noise and power in normal use

Modules run at the standard 1.1V DDR5 voltage without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable across all four slots. No active cooling is included, so adequate case ventilation is necessary for sustained operation.

Questions about this item

Does the 256GB kit arrive as four 64GB modules or must I buy additional sticks?

The kit contains four 64GB DDR5 RDIMMs, giving 256GB total; no extra modules are required.

My Supermicro H14DSG-OM manual lists both 1Rx4 and 2Rx4 options — which rank does this kit use?

This kit uses 2Rx4 organization, matching the board's qualified rank for full-capacity population.

Will the CL52 timing run at the advertised 6400MHz when all four slots are populated?

Yes, the registered ECC design and exact voltage of 1.10V let the memory controller drive all four slots at DDR5-6400 with CL52.
