Exact DDR5-6400 ECC RDIMM for Supermicro H14SSF

This 32GB registered DIMM is built for administrators upgrading or populating the Supermicro H14SSF motherboard. It delivers the precise 2Rx8 rank structure, 1.1V operating voltage and CL52 latency the board's memory controller expects for full-capacity recognition at rated speed.

DDR5 registered ECC limits full-slot population

The DDR5 registered architecture offloads the memory controller so every supported slot can run fully populated at 6400 MT/s while ECC corrects single-bit errors on the fly. Maximum capacity and slot-count rules are defined by the motherboard manual, not by the module itself.

Replaces non-ECC or slower DDR5 that cannot

The jump is worth it when replacing unbuffered or lower-speed DDR5 that forces the controller to downclock or limits population. It is not for systems that require UDIMM or SODIMM form factors or that lack registered-ECC support in the BIOS.

Questions about this item

Should I choose the 32GB single module or a different capacity kit for my Supermicro H14SSF?

This listing is a single 32GB DDR5-6400 RDIMM; add multiple modules to reach your target capacity following the motherboard's population rules.

Will the DDR5-6400 CL52 rating run at full speed once installed in the H14SSF?

The module is spec-matched to the board's memory controller so it is recognised at 6400 MT/s with CL52 timing at 1.1V when populated correctly.

Does the 288-pin RDIMM interface limit how many modules I can install per channel?

The registered RDIMM design offloads the memory controller, allowing every supported slot to run fully populated at the rated 6400 MT/s.
