Four green DDR5 UDIMM modules in anti-static packaging

NEMIX RAM

NEMIX RAM 128GB (4 x 32GB) DDR5 5600 ECC UDIMM memory upgrade

SKU CH-MCCC-KA01Q

A 128GB DDR5 ECC UDIMM kit running at 5600MHz with CL46 latency and 1.1V for Supermicro H14SRV-HLN4F motherboards

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeUnbuffered

Size 128GB 4X32GB

  • 128 GB capacity across four 32 GB modules for large workloads
  • DDR5 5600 speed rated at PC5-44800 for high bandwidth
  • ECC protection corrects single-bit errors to prevent data corruption
  • 1 V operation at CL46 latency for efficient timing
  • Verified fit for Supermicro H14SRV-HLN4F motherboard with 288-pin UDIMM form factor

Exact-match DDR5 ECC UDIMM kit

This 128GB kit contains four 32GB DDR5 5600 modules built to the 288-pin UDIMM form factor with ECC and a 1.10V operating voltage. The CL46 2Rx8 layout matches the memory controller expectations of the Supermicro H14SRV-HLN4F motherboard so the full capacity is recognised at the rated PC5-44800 speed.

Builders who need ECC on this board

The kit suits anyone upgrading the named Supermicro motherboard with verified unbuffered ECC DIMMs that follow its population rules. It will not fit systems that require registered RDIMMs, SODIMM modules or a different DDR generation, and buyers without that specific board should verify their platform’s approved DIMM list first.

Steady throughput with error correction

Under sustained load the on-die ECC corrects single-bit errors continuously, preventing silent data corruption that can accumulate during long compute or storage tasks. The unbuffered design keeps latency consistent while the 1.10V operation maintains thermal stability across extended sessions.

Questions about this item

My Supermicro H14SRV-HLN4F motherboard has four DDR5 slots — will this 128GB kit fill all of them at once?

Yes, the kit contains four 32GB modules for a total of 128GB, so it occupies every DDR5 UDIMM slot on that board.

I plan to keep my existing 32GB DDR5 ECC UDIMM sticks — can I mix them with these new 32GB modules?

Mixing different ranks or timings can prevent the system from training at 5600MHz; the board manual should be checked for approved population rules before adding these 2Rx8 CL46 modules.

After installing the kit, how do I confirm the memory is running at DDR5 5600 with ECC active?

Enter the BIOS or use a Linux command such as dmidecode to verify the speed shows 5600MHz and the ECC status reads enabled for each 288-pin DIMM.
