64GB DDR5 ECC RDIMM for Supermicro H14SHM

This 64GB DDR5 4800 registered ECC module is built for the Supermicro H14SHM motherboard. It delivers the exact rank, voltage and timing the server's memory controller expects so the full capacity is recognised at rated speed.

DDR5 RDIMM population rules and registered buffering

The H14SHM requires 288-pin registered DIMMs and follows specific population rules that vary by configuration. Registered buffering offloads the memory controller, allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly. Buyers who need unbuffered UDIMMs or SODIMMs cannot use this module.

2Rx4 CL40 1.1V specification match

The 2Rx4 organisation, CL40 latency and 1.1V operating voltage must match the board's qualified-vendor list for the memory to train at DDR5 4800. If your system requires a different rank structure, timing or voltage this kit will not operate as intended.

Questions about this item

Should I choose a single 64GB module or a kit for my Supermicro H14SHM?

This listing is a single 64GB DDR5 4800 CL40 2Rx4 1.1V ECC RDIMM. Add the quantity your motherboard manual specifies per channel to reach the desired total capacity.

Will this DDR5 4800 module actually run at 4800 MT/s in my H14SHM?

Yes. The module is spec-matched to the Supermicro H14SHM memory controller, so it is recognised at full capacity and operates at its rated DDR5 4800 speed with CL40 timing.

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

The registered 288-pin RDIMM design offloads the memory controller, allowing every supported slot on the H14SHM to be fully populated at 64GB per module without signal degradation.
