Eight green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 4800 128GB 8x16GB CL40 1.1V ECC RDIMM memory upgrade

SKU CH-1H2B-2Q1N2

Eight 16 GB DDR5 RDIMMs deliver 128 GB of registered ECC memory at 4800 MT/s with CL40 latency and 1.1 V operation, validated for the Supermicro H14SSL-NT motherboard

  • Capacity128GB (8 x 16GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCYes

Size 128GB 8X16GB

Show 24 more configurations
  • Full 128 GB capacity in an 8 x 16 GB kit for dense server deployments
  • DDR5 4800 speed with CL40 timing for rated bandwidth and low latency
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation reduces power draw across all populated slots
  • Verified fitment for Supermicro H14SSL-NT with 288-pin RDIMM form factor

Exact-match DDR5-4800 server kit

This 128GB kit contains eight 16GB DDR5 RDIMMs rated at 4800 MT/s with CL40 timing and 1.1V operation. Registered ECC architecture and 1Rx8 organisation let the memory controller address every slot at full capacity without signal degradation.

For Supermicro H14SSL-NT upgrades only

It suits administrators expanding that specific motherboard to its maximum supported DIMM count with validated rank, voltage and timing parameters. Builders using consumer boards, unbuffered DIMM slots or systems that require a different speed grade should look elsewhere.

Registered ECC RDIMM form factor

The 288-pin registered design is mandatory for the target platform; UDIMM or SODIMM modules will not fit or function. Verify your manual's population rules before installation.

Questions about this item

Will the eight 16 GB modules need individual replacement if one fails?

The kit is sold as a matched 128 GB set; a single faulty module typically means returning the full kit under the lifetime replacement warranty.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s transfer rate sets the peak bandwidth ceiling; CL40 timing determines access delay within that bandwidth envelope.

How much heat and power do the 1.1 V registered DIMMs produce running all day in a fully populated server?

At 1.1 V the modules draw minimal power and have no heat spreader, so they rely on chassis airflow to stay cool during continuous operation.
