Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM MR38400-724K16 2TB 16x128GB DDR5 4800MHz CL40 1.1V ECC Registered RDIMM memory upgrade

SKU CH-98N7-MZHRA

A 2 TB DDR5 server memory kit of sixteen 128 GB registered ECC RDIMMs running at 4800 MHz with CL40 latency and 1.1 V operation, validated for the Supermicro H14DSG-O-CPU motherboard

Show 30 more configurations
  • 2TB capacity with 16 matched 128GB modules for full server population
  • DDR5 4800 speed and CL40 latency deliver rated bandwidth for demanding workloads
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1V operation reduces power draw across all 16 DIMMs in dense configurations
  • Verified fit for Supermicro H14DSG-O-CPU with 288-pin RDIMM form factor

Exact-match DDR5 upgrade

This 2 TB kit contains 16 modules of 128 GB DDR5-4800 ECC Registered RDIMM. It is built for the Supermicro H14DSG-O-CPU motherboard and matches the rank, voltage and timing that board expects. Every stick runs at the rated 4800 MT/s speed when fully populated.

Replaces partial or mismatched kits

When a server runs with fewer than 16 modules or mixes ranks and speeds the memory controller often down-clocks or limits capacity. Installing this matched 16-piece kit restores full 2 TB capacity at CL40 and 1.1 V across all slots without manual tuning.

Suits admins scaling one H14DSG-O-CPU system

The kit is designed for administrators who need maximum registered ECC capacity on this specific Supermicro platform. Builders targeting other motherboards, consumer platforms or unbuffered memory should verify their manual first because population rules and form factor differ.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H14DSG-O-CPU motherboard slots?

Yes, the 288-pin Registered DDR5 form factor matches the H14DSG-O-CPU DIMM sockets exactly; the kit is verified for that board.

What population order should I follow when installing all 16 modules on the H14DSG-O-CPU?

Fill the slots in the sequence shown in the Supermicro H14DSG-O-CPU manual — typically one DIMM per channel per CPU first, then the second rank — to ensure the board trains at 4800 MHz.

Do the Samsung, Micron or Hynix chips on these RDIMMs require any firmware updates or periodic maintenance?

No firmware updates are needed for the DRAM; the modules are sealed with no heat spreader, so only standard server dust cleaning and ECC error-log monitoring apply.
