Exact-match DDR5 upgrade for Supermicro H14DSG-O-CPU

This 64GB DDR5-6400 Registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H14DSG-O-CPU motherboard expects. It installs as a single 288-pin module so the server recognises the full capacity at rated speed. Designed for administrators who need guaranteed compatibility without manual tuning.

DDR5 6400 registered ECC constraints

The registered architecture buffers address and control signals, allowing every slot to run fully populated at 6400 MT/s while ECC corrects single-bit errors on the fly. The module operates at 1.1 V with CL52 latency and a 2Rx4 organisation, so the memory controller must support registered DIMMs at this speed and voltage. UDIMM or SODIMM form factors will not fit or function in this platform.

Plain green PCB with gold-edge 288-pin connector

No heat spreader is fitted, leaving a low-profile circuit board that seats directly into the server's DIMM slots. The gold-plated edge connector ensures reliable contact through repeated thermal cycles in densely packed chassis. Builders should verify the motherboard's population order and maximum supported capacity per slot before installation.

Questions about this item

Should I choose the 64GB DDR5 6400 CL52 2Rx4 module or a different capacity for my Supermicro H14DSG-O-CPU?

This exact-match 64GB DDR5-6400 2Rx4 Registered ECC RDIMM matches the board's required rank, voltage, and timing so it is recognised at full capacity and runs at its rated speed.

What does the 6400 MT/s rating actually deliver once the module is installed in the server?

The module operates at DDR5-6400 (PC5-51200) with CL52 latency at 1.1V, giving the memory controller the precise speed and timing it expects for full-rated performance.

How does the 288-pin RDIMM interface and registered design affect maximum capacity on this motherboard?

The 288-pin Registered RDIMM form factor offloads the memory controller, allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly.
