  • 32 GB kit lets your Supermicro H14DST-F run fully populated at rated speed
  • DDR5-4800 CL40 1Rx8 registered ECC matches the memory controller's exact timing and voltage needs
  • Registered buffer offloads the controller so every slot stays stable at full capacity
  • ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots
  • 288-pin RDIMM form factor fits the board's required DIMM slots not UDIMM or SODIMM

Capacity and speed match

This 32 GB kit delivers two 16 GB DDR5 modules rated at 4800 MT/s with CL40 latency. Registered ECC architecture offloads the memory controller and corrects single-bit errors, so fully populated channels remain stable under sustained server workloads. The 1.1 V operating voltage matches the platform specification exactly.

Headroom and limits

Dual-rank 1Rx8 organisation fills two slots at full rated frequency without downclocking, giving 32 GB of error-correcting capacity for virtualisation, databases or compute nodes. Workloads that exceed 32 GB or need higher bandwidth than PC5-38400 will require additional DIMMs or a faster memory tier.

Build fit and freedom

The 288-pin RDIMM form factor is keyed for the Supermicro H14DST-F motherboard and will not fit UDIMM or SODIMM slots. No heat spreader is present, so airflow across the PCB must be provided by the chassis. Verify the board's population rules before installation to ensure the kit is recognised at full capacity.

Questions about this item

Will this DDR5 4800 CL40 1Rx8 ECC RDIMM kit run at its rated speed alongside existing DDR5 4800 modules in my Supermicro H14DST-F?

The kit matches the board's required DDR5 4800 (PC5 38400), 1Rx8 registered ECC, 1.1V and CL40 specifications, so it will be recognised at full capacity and run at its rated speed when populated per the motherboard manual.

How can I confirm the 32GB 2x16GB DDR5 4800 ECC RDIMM kit is operating correctly after installation?

Enter the BIOS or UEFI and verify the memory reports 32GB total, DDR5 4800 speed, CL40 timings, 1.1V voltage, registered ECC mode and 1Rx8 organisation for each DIMM slot populated.

What is included in the NEMIX RAM MR38400-618K2 box and do I need any extra parts for the Supermicro H14DST-F?

The box contains the 32GB 2x16GB DDR5 4800 CL40 1.1V 288-pin ECC registered RDIMM kit only; no heat spreaders, cables or additional hardware are included or required for installation.
