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

This 768GB kit contains six 128GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10V operation. Registered ECC architecture with 2Rx4 organisation delivers the precise rank, voltage and timing the server memory controller expects for full-capacity recognition and rated-speed operation.

Registered ECC design and six-module population

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 6400 speed while ECC corrects single-bit errors on the fly. The six-module kit matches the board's population rules, eliminating guesswork about mixing capacities or ranks that can reduce bandwidth or prevent boot.

Verify manual for population order

Server and motherboard memory support varies by model, so consult the system or motherboard manual for approved DIMM population order, supported capacities and installation steps before ordering. The kit uses 288-pin DDR5 RDIMM form factor; it will not fit UDIMM or SODIMM slots.

Questions about this item

Will the 128 GB modules need any firmware updates or periodic replacement?

The modules are standard DDR5 6400 CL52 1.1 V registered ECC DIMMs with no firmware; they run for the life of the server unless a physical fault occurs.

What stops me from filling all six slots at 6400 MT/s on the H14DSG-OM?

The memory controller’s maximum supported speed with a fully populated 2Rx4 configuration is the first limit; if the board caps at a lower rate the kit will downclock automatically.

How much heat and power will the 768 GB kit add when the server runs 24/7?

Each 128 GB RDIMM operates at 1.1 V, so total DRAM power stays low and the registered design keeps signal integrity without extra cooling beyond normal chassis airflow.
