  • 48 GB capacity scales Supermicro H14DSG-OD memory to full rated speed
  • DDR5-6400 CL52 timing matches controller spec so modules run at rated frequency
  • Registered ECC architecture offloads memory controller and corrects single-bit errors on the fly
  • 10 V operation with 2Rx8 288-pin RDIMM form factor fits board population rules exactly
  • Lifetime replacement warranty with free US-based technical support backs every module

Exact-match server upgrade

This 48 GB DDR5 6400 CL52 module is built for administrators expanding a Supermicro H14DSG-OD system. The 288-pin RDIMM form factor, 1.1 V operating voltage and registered ECC design match the board's memory-controller requirements so the full capacity is recognised at rated speed.

Build integration

Registered architecture buffers each command, allowing every populated slot to run at 48 GB without overloading the controller. ECC corrects single-bit errors in flight, protecting production workloads from silent corruption and unplanned restarts. Verify the motherboard manual for approved population order before installation.

Sustained-load behaviour

Enterprise-grade Samsung, Micron or Hynix DRAM maintains CL52 timing under continuous throughput. The 1.1 V baseline keeps power draw predictable during long-running database or virtualization tasks, while registered signalling preserves signal integrity across fully populated channels.

Questions about this item

Will the 1.1V operating voltage stay stable when all slots are populated on the H14DSG-OD?

The module is spec'd at 1.10V and uses registered buffering, which reduces electrical load on the memory controller so every populated slot can run at the rated voltage and speed.

How much heat does a 48GB 2Rx8 RDIMM produce without a heat spreader during continuous operation?

Registered ECC modules run at standard 1.1V DDR5 power levels; without a spreader they rely on chassis airflow, so ensure your server's cooling design moves air across the DIMM slots.

Does the Supermicro H14DSG-OD require any specific BIOS setting or DIMM population order for this 48GB kit?

The board's manual defines supported capacities and the exact slot population sequence; follow that guide before installing the 288-pin RDIMMs to guarantee recognition at 6400 MT/s.
