Supermicro H14DSG-OD DDR5 upgrade

This 256GB kit contains four 64GB DDR5 6400 CL52 registered ECC RDIMMs built for the Supermicro H14DSG-OD motherboard. It targets administrators who need maximum memory capacity on that specific platform.

Installation notes

The modules use the 288-pin RDIMM form factor required by the board, not UDIMM or SODIMM, and run at the specified 1.1V. Consult the motherboard manual for the approved population order and seating procedure before installing all four slots.

DDR5 registered ECC limits

Registered buffering lets every slot run fully populated at the rated 6400 speed while ECC corrects single-bit errors on the fly. The kit is validated only for the H14DSG-OD; other Supermicro boards or platforms may have different population rules or voltage requirements.

Questions about this item

How can I confirm the kit is running at DDR5-6400 CL52 after installation?

Check the BIOS or OS memory report; it should show 6400 MT/s with CAS latency 52 across all four slots.

What exactly ships in the box and is anything else required?

The box contains four 64 GB DDR5 288-pin ECC RDIMMs totalling 256 GB; no extra parts are needed for the Supermicro H14DSG-OD.

Should I choose this 256 GB kit or a different capacity for my H14DSG-OD?

Select this 256 GB (4×64 GB) kit when your workload needs the full 256 GB at DDR5-6400 with 2Rx4 registered ECC; pick a smaller kit only if your memory budget is lower.
