Exact-match upgrade for Supermicro H14DSG-OD

This 64GB DDR5 module is built specifically for the Supermicro H14DSG-OD motherboard. It delivers registered ECC operation at the native DDR5 6400 speed your server expects. Server administrators and IT teams can deploy it with confidence that the memory controller will recognise the full capacity immediately.

Registered ECC with 2Rx4 organisation

The single specification that determines fitment is the registered (buffered) RDIMM architecture combined with a 2Rx4 rank structure and 1.1V operating voltage. This exact combination matches the board's memory population rules, allowing every populated slot to run at the rated CL52 latency without downclocking or capacity limits.

288-pin DDR5 RDIMM form factor

The module plugs directly into the motherboard's 288-pin DDR5 RDIMM slots and requires no heat spreader clearance. It frees the memory controller from electrical loading when all slots are filled, while on-die ECC corrects single-bit errors before they reach production workloads. Verify your system manual for approved population order before installation.

Questions about this item

Will the DDR5 6400 speed run at its rated 6400 MT/s on my Supermicro H14DSG-OD?

Yes, this kit is an exact-match upgrade verified for the H14DSG-OD. The board's memory controller will recognise the 2Rx4 registered ECC modules at 1.10 V and CL52, allowing full 6400 MT/s operation when populated per the manual.

What does the 288-pin registered ECC RDIMM form factor mean for installation?

The 288-pin RDIMM is the only DIMM type the H14DSG-OD accepts; it will not fit UDIMM or SODIMM slots. Registered buffering lets every slot run fully populated at 64 GB per module while ECC corrects single-bit errors on the fly.

Does the module need a heatsink or extra clearance in a 1U chassis?

No heatsink is fitted, so the bare PCB sits at standard RDIMM height. This keeps it compatible with tight 1U air baffles, but always verify your specific chassis airflow guide before installing.
