  • 128 GB total capacity lets you fully populate the Supermicro H14SHM
  • DDR5 4800 MT/s speed matches the motherboard's rated memory frequency
  • Registered ECC RDIMM design offloads the memory controller and corrects single-bit errors
  • 1 V operating voltage aligns with the platform's DDR5 power spec
  • 4 x 32 GB 2Rx8 modules follow the board's population rules for full recognition

Exact-match DDR5-4800 kit for Supermicro H14SHM

This 128GB kit contains four 32GB DDR5 4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14SHM memory controller expects. Each module is a 288-pin 2Rx8 part operating at 1.10V with CL40 latency, so the board recognises the full capacity and runs at its rated speed without manual tuning.

Sustained-load behaviour with registered ECC

Registered architecture offloads the memory controller, allowing every slot to stay fully populated at full capacity during continuous workloads. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots that would otherwise interrupt production services running for hours or days.

Verify population rules and manual before ordering

Server and motherboard memory support varies by model, so consult the Supermicro H14SHM manual for supported capacities, approved DIMM population order and installation steps. This kit is not for systems that require UDIMM or SODIMM form factors, nor for builds that cannot use Registered ECC DDR5 modules.
