  • 384 GB total capacity from six 64 GB modules for dense server workloads
  • DDR5 5600 speed with CL46 latency delivers rated throughput on the H14DSH
  • Registered ECC RDIMM architecture offloads the memory controller and corrects single-bit errors
  • 1 V operation matches the motherboard's voltage requirement for stable full-population runs
  • 288-pin 2Rx4 form factor fits the H14DSH DIMM slots and population rules

Exact-Match DDR5 Server Upgrade

This NEMIX RAM kit delivers 384GB across six 64GB DDR5 5600 RDIMMs built to the Supermicro H14DSH motherboard's exact specifications. Registered ECC modules with 2Rx4 organisation and CL46 timing at 1.1V ensure the memory controller recognises full capacity at rated speed without manual tuning. It targets administrators who need maximum supported density in a validated configuration.

Replacing Smaller or Mixed Kits

The kit replaces partial populations or mixed-capacity DIMMs that force the server to run at reduced speeds or disable ranks. A full six-module matched set avoids population-rule conflicts and lets every channel operate at DDR5 5600 (PC5 44800) with ECC protection active. The jump is worth it when workloads demand the full 384GB address space and registered buffering for sustained throughput.

Verify Manual Population Rules

Before ordering, consult the H14DSH manual for the approved DIMM installation sequence and maximum supported capacity per processor. Confirm the board revision accepts 2Rx4 Registered ECC RDIMMs at 1.1V and that your BIOS version enables the target speed. Installing outside the documented order can prevent boot or limit usable memory.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DSH motherboard?

Yes, the kit uses the 288-pin Registered DDR5 RDIMM form factor that the H14DSH requires; it is not a UDIMM or SODIMM and matches the board's physical slot layout.

What is the correct population order for the six 64GB modules on the H14DSH?

The H14DSH manual defines a specific DIMM population sequence for full-capacity operation; follow that exact slot order so the memory controller recognises all 384GB at DDR5-5600 CL46.

Do the modules need active cooling or heat-spreader maintenance over time?

The modules have no heat spreader and run at the standard 1.1V DDR5 voltage; normal server airflow is sufficient and no periodic cooler maintenance is required.
